Introduction to the System
This chapter introduces the analyzer's HP instrument BASIC (IBASIC) and describes how to
connect and use a keyboard. Read this chapter before using HP instrument BASIC with the
analyzer for the rst time. The topics covered in this chapter are:
Overview of HP instrument BASIC
Connecting the keyboard
Using HP instrument BASIC for the rst time
Using the keyboard
Entering BASIC Statements from the front panel keys

Overview of HP instrument BASIC
HP instrument BASIC (IBASIC) can be used for a wide range of applications from simple
recording and playback of measurement sequences to remote control of other instruments.
HP instrument BASIC is a complete system controller residing inside your analyzer. It
communicates with your analyzer via GPIB commands and can also communicate with other
instruments, computers, and peripherals over the GPIB interface.

Introduction to the System 2-1
Figure 2-1. Conguration Example of the HP instrument BASIC System
The HP instrument BASIC's programming interface includes an editor and a set of programming
utilities. The utilities allow you to perform disk I/O, renumber, secure, or delete all or part of
your program.
The HP instrument BASIC command set is similar to the command set of HP 9000 Series
200/300 BASIC. Therefore, HP instrument BASIC programs can be run on any HP BASIC
workstation with few if any changes. Porting information can be found in the HP instrument
BASIC Programming Techniques of the HP instrument BASIC Users Handbook.

Connecting the Keyboard
Note Turn OFF the analyzer before inserting or removing the keyboard connector.

When you use HP instrument BASIC, connect the furnished keyboard to the mini-DIN
connector on the rear panel.

2-2 Introduction to the System
Using HP instrument BASIC for the First Time
Allocating Screen Area for HP instrument BASIC

The total screen area is reallocated as the analyzer display.
4. Press the following softkey:
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

HALF INSTR HALF BASIC
The screen area is allocated so that the upper half of the screen is used for the analyzer
operation and the lower half is used for HP instrument BASIC.
5. Press the following softkey:
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

BASIC STATUS
Three blank lines appear at the display line (lower area of the screen). This area is used by
HP instrument BASIC to input commands and to display messages.
More information on the display allocations for the HP instrument BASIC area is described in
\4Display5" in Appendix D.

Setting the Size of Memory Area for HP instrument BASIC

The size of the memory areas for the RAM disk memory and the variable of HP instrument
BASIC (excluding common variables) can be changed according to your application.
Caution When the memory partition is recongured, the analyzer goes to the initial
settings. That is, the RAM disk memory is initialized and all the data saved in
the RAM disk memory is destroyed, and the program on the BASIC editor is
destroyed.

Controlling the Analyzer

HP instrument BASIC can control the analyzer (itself) through the \internal" GPIB bus. This
means that an analyzer with HP instrument BASIC includes both a controller and an analyzer
in the same instrument. They are connected through an internal GPIB bus.
Note The select code of the internal GPIB interface is 8, and the GPIB address of the
analyzer can be any number from 0 to 30. In this manual, we use \800" for the
device selector of the analyzer.
For more information on GPIB addresses and device selectors, see \Device
Selectors" in the HP instrument BASIC Interfacing Techniques of the HP
instrument BASIC Users Handbook and \Available I/O Interfaces and Select
Codes" in Chapter 8.

Saving and Getting Programs
This chapter describes how to save and get programs to or from the built-in exible disk drive
and RAM disk memory. Topics of this chapter are:
Saving programs (SAVE)
Listing le names (CAT)
Getting programs (GET)
If you are using the disk drive for the rst time, see \To Save and Recall" in Chapter 6 of the
Task Reference.
Note HP instrument BASIC on the analyzer cannot communicate with an external
disk drive.

Note The analyzer can use either LIF (Logical Interchange Format) or DOS (Disk
Operating System) formatted disks. The instrument automatically detects the
disk format. It can use most of the same operations for either disk format.

Saving Programs (SAVE)
1. To use the built-in disk drive, insert a 2DD disk or 2HD disk into the disk drive.
2. If you are using a exible disk for the rst time, set the disk format to LIF or DOS and
initialize the disk.
Note Floppy disks can be initialized in the 2HD format only.

Note When the analyzer is turned on, the RAM disk memory is automatically
initialized by the format that is set by FORMAT [ ] under FILE UTILITY
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

under 4Save5. If you want to change the disk format, initialize it.

3. If the display allocation is ALL INSTRUMENT, change the allocation. For example:
NNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNN

4Display5 MORE ALL BASIC
4. Specify the system mass storage device as follows:
When you want to use the built-in disk drive, type in MSI ":INTERNAL,4" or MSI ":,4",
then press 4Return5.

Saving and Getting Programs 4-1
When you want to use the RAM disk memory, type in MSI ":MEMORY,0" or MSI ":,0",
then press 4Return5.
5. Press the following key among the 3 menus which leads to the 4Shift5 - 4F95 key. And type in
the lename to which you will store the program as follows:
NNNNNNNNNNNNNN

SAVE le name 4Return5
You can also save the le from the keyboard. Type and press as follows:
SAVE le name 4Return5
The program is stored on the disk.
Note If you get the error 0257, \File name error", a le on the disk already has the
name you are trying to use. In this case, you have three choices:
Pick a new le name that doesn't already exist. To determine which le
names are already being used, use the \CAT" command (see below).
Replace an existing le, use the \RE-SAVE" statement.
Purge the old le using the PURGE command, then save the new one.

Listing File Names (CAT)
Listing to Screen

Press the following keys and softkeys:
1. If the display allocation is ALL INSTRUMENT or BASIC STATUS, change the allocation to
either HALF INSTRument HALF BASIC or ALL BASIC. For example:
NNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNN

4Display5 MORE ALL BASIC
2. Press the following key among the 3 menus which leads to the 4Shift5 - 4F95 key:
NNNNNNNNNNN

CAT 4Return5

You can list from the keyboard as follows:
Type in CAT then press 4Return5.
The le names stored on the disk are listed on the screen.
Note Because the CAT statement outputs 80 columns to a line and the maximum
number of columns to a screen is 61, each line is wrapped at the 62th column.
If you do not want the list to wrap around, execute the following statement
before executing the CAT command.
PRINTER IS LCD;WIDTH 80
CAT will list the le names with no wrap around, but anything after the 62th
column in the output cannot be seen.

4-2 Saving and Getting Programs
Listing to Printer

Note For hard copy output, a parallel cable must connect the analyzer to the printer.

1. Set the output device to be a printer as follows:
PRINTER IS PRT;WIDTH 80 4Return5
2. Type and press as follows:
CAT 4Return5

The program is listed on the printer.
3. Get the output device back to CRT:
PRINTER IS LCD 4Return5

Getting Programs (GET)
You can retrieve a program from the disk as follows:
1. If the display allocation is ALL INSTRUMENT, change the allocation to either HALF
INSTRument HALF BASIC or ALL BASIC. For example:
NNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNN

4Display5 MORE ALL BASIC
2. Press the following key among the 3 menus which leads to the 4Shift5 - 4F95 key and type the
lename you want to retrieve:

Program I/O
This chapter describes how to write programs that use the LCD, the I/O port, the external
RUN/CONT connector in the analyzer, and the DOS le system.
Topics covered in this chapter are:
Graphics
Using the external RUN/CONT connector
File system exceptions
Using the I/O port in BASIC programs

Graphics
HP instrument BASIC adds graphics capability to the analyzer. You can draw pictures on the
LCD display independent of the grids and traces.
The analyzer has two screens, the instrument screen and the graphics screen. These two
screens are always displayed together on the LCD and are not separately selectable. The
instrument screen consists of a trace display area and a softkey label area. The HP instrument
BASIC editor is also displayed on the trace display area. The graphics screen covers the
entire instrument screen as shown in Figure 6-1. The graphics screen is like an independent
transparent overlay in front of the instrument screen. Therefore, you can draw gures in both
the trace display and softkey label areas.

Figure 6-1. Screen Structure

Program I/O 6-1
Each point on the graphics screen is addressable using a coordinate address as shown in
Figure 6-1. The bottom left corner is the origin (0,0) and the top right corner is the maximum
horizontal and vertical end points (610,420). The MOVE and DRAW statement parameters are
specied using these coordinate values. Because the aspect ratio of a graphics screen is 1, you
need not adjust the aspect ratio when drawing gures.

HP instrument BASIC Graphics Commands

The analyzer's HP instrument BASIC has three graphics commands; MOVE, DRAW, and
GCLEAR.
MOVE Moves the pen from its current position to the specied coordinates.
DRAW Draws a line from the current pen position to the specied coordinates.
GCLEAR Clears the graphics screen, moves the pen from its current position to the
origin (0,0), and selects pen 1.
Note The total times of executing the MOVE and DRAW commands is up to 1933, even
if the pen position is not changed.

Hard Copies

Graphics hard copies can be obtained with the printing function.
PRINT
under 4Copy5 prints a display image on a printer. See \Copy Menu" in Chapter 9 of the
NNNNNNNNNNNNNNNNN

PRINT
Function Reference.

Initial settings

When power is turned ON, the default settings are as follows:
MOVE 0,0

Example of Graphics Programming

This section describes an example of a simple program for drawing lines on the graphics screen.
Drawing a Straight Line
The following HP instrument BASIC program will draw a line from coordinate (50,200) to
coordinate (300,200) on the display.
GCLEAR ! INITIALIZE GRAPHICS MODE
MOVE 50,200 ! MOVE PEN TO COORDINATE (50,200)
DRAW 300,200 ! DRAW A LINE TO COORDINATE (300,200)
END
Drawing a Circle
Trying to express all graphical images using only straight lines is tedious, slow, and dicult.
This example describes a subprogram you can use to draw a circle. It can draw a circle by
passing the center coordinates and the radius as arguments to the following subroutine. This
subroutine can be used as a base for drawing arcs, setting dierent values for Theta, etc.
SUB Drawcircle(Centx,Centy,R) !

6-2 Program I/O
DEG ! USE DEGREES FOR ANGLE EXPRESSIONS
X=Centx+R !
Y=Centy !
MOVE X,Y ! MOVE PEN TO INITIAL POINT
For Theta=1 to 360 !
X=INT(COS(Theta)*R+Centx) ! NEXT X COORDINATE ON CIRCLE
Y=INT(SIN(Theta)*R+Centy) ! NEXT Y COORDINATE ON CIRCLE
DRAW X,Y ! DRAW LINE TO NEXT POINT ON CIRCLE
NEXT Theta ! UNTIL STARTING POINT IS REACHED
SUBEND !

Using the External RUN/CONT Connector
You can use the RUN or CONT commands in a program by inputting a TTL-compatible signal to
the External RUN/CONT connector on the rear panel. At the negative-going edge of a pulse
more than 20 s wide (Tp ) in the LOW state will trigger RUN or CONT.

Figure 6-2. RUN/CONT Trigger Signal

File System Exceptions
The analyzer supports both the LIF and DOS le formats. When using an LIF format disk, the
CREATE and CREATE DIR commands will generate an error.
Because the analyzer does not support an external disk drive, the MASS STORAGE IS
(MSI) statement cannot specify volumes other than the built-in disk drive (volume specier
\INTERNAL,4", the default volume) and RAM disk memory (volume specier \MEMORY,0").

Program I/O 6-3
Using the I/O Port in BASIC Programs
The HP instrument BASIC can directly control the I/O port without using GPIB commands. This
is faster than using the INP8IO? and OUTP8IO GPIB commands.
READIO(15,0) Reads the 4-bit data from the I/O Port and returns a decimal value.
WRITEIO 15,0;data Outputs the decimal value of the 8-bit data to the OUT 0 to 7 lines of
the I/O port. The OUT 0 signal is the LSB (least signicant bit), while
the OUT 7 signal is the MSB (most signicant bit).
See Appendix B for more information on READIO and WRITEIO commands.
For more information on the I/O port, see Appendix B.

Special Features and Advanced Techniques
The topics covered in this chapter are :
Autoloading and running a program automatically (AUTOST)
On Key Label function
Increasing program speed

Autoloading and Running a Program Automatically (AUTOST)
The analyzer allows you to create a special program le called AUTOST. This program is
automatically loaded and run every time the analyzer is turned ON.
When you use this capability, the disk on which you saved AUTOST must be inserted in the
disk drive before the analyzer is turned ON.
The system rst checks to see if there is an AUTOREC le on the disk. If there is, the system
reads the AUTOREC le to set up the analyzer, and then loads and runs the AUTOST program.
(For more information on AUTOREC, see \Auto Recall Function" in Appendix D of the
Function Reference.)

On Key Label Function
The HP instrument BASIC allows you to dene softkeys from within a program. The softkey
labels you dene will appear when pressing the 4Shift5 - 4F105 key on the Keyboard. The labels
are displayed while running the program.
The ON KEY statement is used to dene the softkeys. For example:
......
100 ON KEY 1 GOTO 150
110 ON KEY 2 LABEL "Print" GOSUB Report
......
You can also use the KEY statement or USKEY command to automatically display the label.
This prevents you to press 4Shift5 - 4F105 keys or the ON KEY LABELS softkey while the user
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

program is running. The KEY statement is used to display the softkey labels dened. The
following set of statements is the same as the key strokes 4System5 IBASIC ON KEY LABELS :
NNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

......
200 OUTPUT @Hp4352;"KEY 47" ! SYSTEM key
210 OUTPUT @Hp4352;"KEY 0" ! IBASIC softkey
220 OUTPUT @Hp4352;"KEY 7" ! ON KEY LABELS softkey
......
Note that the same result can be obtained with the program shown below.

Special Features and Advanced Techniques 7-1
......
200 OUTPUT @Hp4352;"USKEY"
......
For more information on the ON KEY statement, see the HP instrument BASIC Language
Reference of the HP instrument BASIC Users Handbook.

Increasing Program Speed
Because the analyzer's CPU interleaves processing measurements and executing a program,
program execution speed depends on the measurement conditions. The display process also
requires processing time.
To increase program speed (increase throughput), set the analyzer to the following conditions:
If you do not need to measure the dut when executing a program, set TRIGGER MODE to
HOLD.
If you need to measure the dut but do not need to display the traces on the screen, set
DISPLAY ALLOCATION to ALL BASIC.
When you use the I/O port, use the READIO and WRITEIO commands to input or output data
to the port directly.
Turn the Display Params o.

Analyzer Specic HP instrument BASIC Features
This chapter lists and summarizes the HP instrument BASIC features specic to the analyzer.
Details of each feature are described in the previous chapters and in the appendixes.
This chapter covers the following topics:
Available I/O interfaces and select codes
Storage units
GPIB commands for HP instrument BASIC

Available I/O Interfaces and Select Codes
Available interfaces and their select codes in the analyzer's HP instrument BASIC are listed in
the following table:
Select Codes Devices
1 LCD
2 Keyboard
7 External GPIB interface
8 Internal GPIB interface
15 12 bit I/O port
16 24 bit I/O port

Storage Unit
The analyzer has two types of storage units: the built-in exible disk drive and the RAM disk
memory. Both the disk drive and RAM disk memory support the LIF and DOS formats.
To switch the system's storage units between the disk in the disk drive and the RAM disk under
control of HP instrument BASIC,
MSI ":INTERNAL,4" or MSI ":,4" for the built-in disk drive
MSI ":MEMORY,0" or MSI ":,0" for the RAM disk memory

Analyzer Specic HP instrument BASIC Features 8-1
Note When you want to manage the storage units using the following GPIB
commands, use the STODDISK command (for the built-in disk drive) or the
STODMEMO command (for the RAM disk memory) to specify the storage unit.

CHAD INID RESAVD SAVDGRA
CRED PURG SAVDASC SAVDSTA
DISF RECD SAVDDAT

To copy a le between the disk and RAM disk, use an FILC command.
Note The FILC command cannot be used to copy a le if the format (LIF or DOS) of
the disk in the built-in disk drive is dierent from that of the RAM disk.

Use the front panel key or enter an GPIB command to initialize the storage unit. When using
an GPIB command to initialize the storage unit, execute the following procedure:
d a
10 ASSIGN @Hp4352 TO 800
20 OUTPUT @Hp4352;"STODDISK" ! Selects the built-in disk drive
30 OUTPUT @Hp4352;"DISF DOS" ! Selects the DOS format
40 OUTPUT @Hp4352;"INID" ! Initializes the disk
50 END
c b
Built-in Flexible Disk Drive

The analyzer's HP instrument BASIC has the following disk drive limitations:
Disk types which can be initialized by the analyzer's HP instrument BASIC INITIALIZE
statement is 2HD (1.4 MB). 2DD disks cannot be initialized.
The only INITIALIZE format option is the default (256 byte/sector).
DOS formats supported. The DOS formats supported are:
720 Kbyte, 80 tracks, double-sided, 9 sectors/track
1.44 Mbyte, 80 tracks, double-sided, 18 sectors/track
HFS format is not supported.
External disk drives are not supported.

RAM Disk Memory

A part of the RAM of the analyzer can be used as a virtual disk drive; RAM disk memory. RAM
disk memory can be operated in the same way as the internal disk drive.
When the analyzer is turned OFF, the data saved in the RAM disk is lost, and the RAM
disk memory is automatically initialized by the format that is set by FORMAT [ ] under
