Hewlett-Packard to Agilent Technologies Transition
This documentation supports a product that previously shipped under the Hewlett-
Packard company brand name. The brand name has now been changed to Agilent
Technologies. The two products are functionally identical, only our name has changed. The
document still includes references to Hewlett-Packard products, some of which have been
transitioned to Agilent Technologies.

Safety Symbols
The following safety symbols are used throughout this manual. Familiarize yourself with each
of the symbols and its meaning before operating this instrument.
Caution The caution sign denotes a hazard. It calls attention to a procedure which, if
not correctly performed or adhered to, could result in damage to or destruction
of the instrument. Do not proceed beyond acaution sign until the indicated
conditions are fully understood and met.
Warning The warning sign denotes a hazard. It calls attention to a procedure
which, if not correctly performed or adhered to, could result in injury
or loss of life. Do not proceed beyond a warning sign until the indicated
conditions are fully understood and met.
General Safety Considerations
Warning Before this instrument is switched on, make sure it has been properly
grounded through the protective conductor of the ac power cable to a
socket outlet provided with protective earth contact.
Any interruption of the protective (grounding) conductor, inside or
outside the instrument, or disconnection of the protective earth terminal
can result in personal injury.
Warning There are many points in the instrument which can, if contacted, cause
personal injury. Be extremely careful.
Any adjustments or service procedures that require operation of the
instrument with protective covers removed should be performed only by
trained service personnel.
Caution Before this instrument is switched on, make sure its primary power circuitry
has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause damage to
the instrument when the ac power cable is plugged in.

How to Use This Guide
Where to Start
If you have just received your spectrum analyzer and want to get ready for use for the first
time, do the following:
n Read Chapters 1 and 2 of the HP 8590 Series Spectrum Analyzer User's Guide.
n Perform the initial self-calibration routines described in Chapter 2 of the HP 8590 Series
Spectrum Analyzer User's Guide (these are automatic self-checks and require no test
equipment).
n If you need to verify the unit is operating within its specifications, perform the performance
verification tests in Chapter 1 of this guide.
After completing the performance verification, use the HP 8590 Series Spectrum Analyzer
User's Guide to learn how to use the spectrum analyzer and to find more detailed information
about the spectrum analyzer, its applications, and key descriptions.
This guide uses the following conventions:

Calibrating
This chapter contains performance test procedures which test the electrical performance of the
spectrum analyzer.
Allow the spectrum analyzer to warm up in accordance with the Temperature Stability
specification in Chapter 2 before performing the tests in this chapter.
None of the test procedures involve removing the cover of the spectrum analyzer.
Calibration
Calibration verifies that the spectrum analyzer performance is within all specifications listed in
Chapter 2. It is time consuming and requires extensive test equipment. Calibration consists of
all the performance tests. See `Ihble l-l for a complete listing of the performance tests.
Operation Verification
Operation verification consists of a subset of the performance tests. See Table l-l. Operation
verification tests only the most critical specifications of the spectrum analyzer. These tests are
recommended for incoming inspection, troubleshooting, or after repair. Operation verification
requires less time and equipment than the calibration.
HP 859013 Spectrum Analyzer Calibrating l-l
The following table lists the performance tests included in this chapter. Select the spectrum
analyzer option being calibrated and perform the tests marked in the option column. Note that
some of the tests are used for both calibration and operation verification (marked with 0).

Safety
Familiarize yourself with the safety symbols marked on the pulse generator, and read the
general safety instructions and the symbol definitions given in the front of this manual before
you begin verifying performance of the pulse generator.
Before You Start
There are four things you should do before starting a performance verification test:
n Switch the spectrum analyzer on and let it warm up in accordance with the Temperature
Stability specification in Chapter 2.
n Read "Making a Measurement" in Chapter 2 of the HP 8590 Series Spectrum Analyzer User's
Guide.
n After the spectrum analyzer has warmed up as specified, perform the Self-Calibration
Procedure documented in "Improving Accuracy With Self-Calibration Routines" in
Chapter 2 of the HP 8590 Series Spectrum Anulyzer User's Guide. The performance of the
spectrum analyzer is only specified after the spectrum analyzer calibration routines have
been run and if the spectrum analyzer is autocoupled.
n Read the rest of this section before you start any of the tests, and make a copy of the
Performance Test Record described in "Recording the Test Results."
Test equipment you will need
Tables l-2 through l-4 lists the recommended test equipment for the performance tests. The
tables also lists recommended equipment for the spectrum analyzer adjustment procedures
which are located in the HP 85900 Spectrum Anulyzer Service Guide. Any equipment that
meets the critical specifications given in the table can be substituted for the recommended
model.
Recording the test results
A performance test record is provided at the end of this chapter.
Each test result is identified as a TR Entry in the performance tests and on the performance
test record. We recommend that you make a copy of the performance test record, record the
test results on the copy, and keep the copy for your calibration test record. This record could
prove valuable in tracking gradual changes in test results over long periods of time.
If the spectrum analyzer doesn't meet specifications
If the spectrum analyzer fails a test, rerun the frequency calibration and amplitude calibration
routines by pressing CAL FREQ B AMPTD . Press CAL STORE , then repeat the verification test.
If the spectrum analyzer still fails one or more specifications, complete any remaining tests and
record all test results on a copy of the test record. Then refer to Chapter 3, "If You Have a
Problem," for instructions on how to solve the problem.
HP 8590D Spectrum Analyzer Calibrating 1-3
Periodically verifying operation
The spectrum analyzer requires periodic verification of operation. Under most conditions
of use, you should test the spectrum analyzer at least once a year with either operation
verification or the complete set of performance verification tests.

Option 013
This procedure is only for spectrum analyzers equipped with Option 013.
The frequency readout accuracy of the spectrum analyzer is tested with an input signal of
known frequency. By using the same frequency standard for the spectrum analyzer and the
synthesized sweeper, the frequency reference error is eliminated.
The related adjustment for this performance test is the "Sampler Match Adjustment."

n Record the Noise Sideband Suppression in the performance test record as TR Entry 3-l.
The suppression should be L-65 dBc.
