Service Handling Precautions
Service work or calibration should only be carried out by skilled engineers. Please note the following points before commencing work. The tracks on the printed circuit board are very fine and may lift if subjected to excessive heat. Use only a miniature temperature controlled soldering iron and remove all solder (on both sides of the joint) with solder wick or suction before attempting to remove a component. Many of the integrated circuits are CMOS devices and care should be taken when handling to avoid damage by static discharge.
Dismantling the instrument
1. 2. 3. Invert the instrument and remove the 4 screws next to the rubber feet. Lift off the case lower ensuring the front and rear panels stay with the case upper. To remove the pcbs and front panel assembly, remove the 6 screws securing the main pcb to the case upper. The 2 central screws are accessible through holes in the control and sweep pcbs. Reassemble in the reverse order.

IMPORTANT NOTE
From February 1999 IC1 on TG215/TG230 becomes a PIC microcontroller, replacing the TSC821 measurement IC which had become obsolete. In addition to a completely new Display pcb the circuitry on the Main pcb associated with measurement and display also changed and some component values on the Control board changed too. In the following sections the original design is referred to as VERSION 1 and the new microcontroller design as VERSION 2; full schematics are given for both versions. The changes apply from Serial No. 109136 for TG215 and from No. 109198 for TG230. TG210 descriptions, Parts Lists, etc. remain unchanged whether built on the original or new Main pcb.

Functional Description
The relationships between the major circuit elements are shown in the block diagram. The summing amplifier sums the voltages from the dial, sweep input and the sweep board and its output controls the magnitude of the complimentary current source and current sink. This current varies from approximately 1.7uA to 1.7mA for a 1000:1 frequency change (.002 - 2.0). The symmetry control adjusts the ratio between the current source and current sink. The diode gate steers current into and out of the range multiplier capacitor and is controlled by the comparator output. When the comparator output is high the charge on the capacitor will rise, linearly, producing the positive going triangle slope. When the comparator output is low the charge on the capacitor will fall linearly producing the negative going triangle slope. The triangle amplifier has unity gain and buffers the triangle wave on the multiplier capacitor to drive the comparator and output circuits. The comparator operates as a window detector with fixed limit points set to the triangle peaks. One of its two outputs drives the TTL/CMOS output. The other output is level shifted to drive the diode gate and squarewave shaper. When the comparator output to the diode gate is high the triangle wave is positive going until this reaches approximately +1V, when the comparator output switches low. When the comparator output is low the triangle wave is negative going until it reaches approximately -1V, when the comparator goes high , and the cycle is repeated. This basic function generator loop is shown by the double arrows in the block diagram. Triangle and squarewave are generated simultaneously as shown. To achieve the 20Hz and 2Hz ranges, the currents into the diode gate are divided by 10 and 100 respectively. The sinewave converter uses the non-linear characteristics of a transistor pair to convert the triangle wave into a sinewave. The selected function is amplified by the pre-amp and applied to the amplitude control directly or via the amplitude modulator. The signal is summed with the voltage from the DC offset control at the output amplifier, which amplifies the signal up to 20V peak to peak to drive the main output socket. The digital display measures frequency on the 2kHz to 2MHz ranges, and measures voltage at the summing amplifier on the 2Hz to 200Hz ranges. Amplitude and offset are measured in the voltage mode. The sweep generator provides a triangle wave with variable amplitude and speed that is summed with the dial at the summing amplifier. The power supply converts the incoming AC line voltage to the DC rails required by the instrument.

Circuit Descriptions
Power Supply - Mains Operating Voltage
The operating voltage is indicated by the orientation of the fuseholder. When the 230V marking is upwards the unit is set for operation over the range 198V to 264V. When the 115V marking is upwards the unit is set for operation over the range 99V to 132V. To change the operating voltage range, remove the AC line plug, pull out the fuse holder, replace the fuse with one of the appropriate rating (see below) and rotate the fuse holder before pushing it firmly back into place. (The transformer is also tapped at 100V for special requirements).
Fuse
The correct fuse must be fitted after an operating voltage change. Only a time-lag fuse should be fitted. For 230V operation use 125mA 250V time-lag For 115V operation use 250mA 250V time-lag. WARNING ! - THIS INSTRUMENT MUST BE EARTHED Any interruption of the protective conductor inside or outside the instrument or disconnection of the protective earth terminal is likely to make the apparatus dangerous. Intentional interruption is prohibited.
Power Supply - DC Regulation
Diode bridge comprising D32 to D35 rectifies the transformer output and C32 and C33 are the reservoir capacitors which supply the ±15V regulators; fine adjustment is provided by VR16 and VR17. The ±12V rails are derived from the ±15V rails with D37 and D39. IC24 is a +5V regulator and D2 generates the -5V.
Waveform Generation - Summing Amplifier and Current Sources
The dial and sweep voltages are summed by IC2D; the output range of the amplifier is approximately -4mV to -4V for a 1000:1 frequency change. Q1 gives increased current drive to drive R39 and R47. When the symmetry button is depressed R39 and R47 are increased by a factor of 10 with the symmetry control in mid-position, decreasing the output frequency by a factor of 10. This allows a symmetry range of 10:1. On the 2Hz to 200Hz ranges on TG230, Q33 and IC17B signal the voltmeter to divide by 10 in frequency mode. IC2C refers the output of IC2D to the +12V rail, IC4 and Q5 mirror this into the diode gate. IC2A inverts the output of IC2D, IC2B refers it to the -12V rail, IC9 and Q17 mirror this into the diode gate.
Waveform Generation - Range Selection and Triangle Amplifier
Ranges 200Hz to 2MHz use decade steps of range capacitor. The 20Hz range uses C11 and reduces the charging current one decade by selecting R61 and R51; the 2Hz range also uses C11 and reduces the charging current by a another decade by selecting R59 and R50. The triangle amplifier uses Q7 as a source follower and Q8 as a current source; Q7 and Q8 are Idss matched. Q9 is an emitter follower to give low output impedance. The stage has unity gain and the offset is trimmed by VR5.
Waveform Generation - Comparator and Aux Output
IC5 operates as a window detector and determines the peak to peak amplitude of the triangle wave on the range capacitor, which is approximately ±1V. Capacitors C15 to C19 compensate for comparator delay ensuring that the triangle wave amplitude remains constant with increase in frequency. The two internal NAND gates in IC5 are wired as a flip-flop to ensure positive switching of the comparator. C71 and C77 provide a small amount of positive feedback to ensure jitter-free operation. Q6 level shifts the output of IC5 to be about ground, to drive the diode gate. IC6 drives the Aux Output with a TTL/CMOS compatible signal. 7
Waveform Generation - Waveform Shaping
The sine shaper comprises a monolithic transistor array IC12 which is driven by the triangle amplifier. The circuit has two non linear stages. A pair of emitter followers A and D round the peaks of the triangle; the output of this stage is impressed across R80 and R82 in series and applied to the second stage. This comprises a differential pair B and C driven almost into cut-off and converts the clipped triangle into a sinewave. VR7 adjusts the gain of this pair to bring them close to cut off and therefore minimum sinewave distortion. VR27 adjusts the dc operating point of the sinewave converter to give symmetrical operation on both positive and negative halves of the waveform. The squarewave shaper is a diode bridge D13 to D16, driven by a level shifter Q10, which steers current into and out of R55 and C61. This gives a clean waveform which is symmetrical about ground. When square wave is not selected SW10B connects R77 to +5V turning off Q10.
Preamplifier
The selected waveform passes to the preamplifier. Q19 and Q20 form a long tailed pair and are in thermal contact. Emitter follows Q21 and Q22 give low output impedance and gain is set by feedback resistor R163. The amplifier is inverting.
Output Amplifier
The output amplifier is non-inverting. Q23 and Q24 form a long-tailed pair and are in thermal contact. Q25 operates in common base and forms a cascode stage in conjunction with Q24. The collector load for Q25 is current source Q27. Q26 and Q28 are complementary emitter followers. The gain of approximately 10 is set by R136 and R134. The DC Offset control is buffered by IC18D and applied via R133.
Amplitude Modulator (TG230)
When the AM button is depressed, the amplitude modulator is inserted between the preamplifier and the output amplifier. IC19 is a balanced modulator. Q29 to Q32 form a differential amplifier which amplifies the difference between the open collector outputs of IC19. IC18B is a 400Hz Wien Bridge oscillator; LP1 provides amplitude stabilisation. IC18A buffers the signal on the modulation depth control VR22 and also sets the dc bias for IC19.
Sweep (TG220/230)
RAMP GENERATOR The rate control VR20 determines the magnitude of the current source IC7A and Q18. This current is steered into and out of C54 by the operational transconductance amplifier (OTA) IC8. The voltage on C54 is buffered by IC7B to drive the stop control VR21 and the window comparator IC10A and IC10B. The thresholds of the window comparator determine the limits of the ramp which are 0V and +4V. Q13 and Q14 are level shifters to drive flip flop IC11A. the output of IC11A is level shifted by R20 and R30 and clamped by D5 and D6 to be symmetrical about 0V. When the input to IC8 is high the OTA sources current into C54; when the input is low the OTA sinks current from C54. This loop is very similar to a function generator. If either the set start or set stop buttons are depressed the loop is closed around the ramp generator forcing the ramp to be held precisely at its lower or upper limit. IC10D buffers the signal on VR21 to drive the main board directly or via the log converter. LOG CONVERTER IC3D sums the output of the ramp generator with an offset current to drive the logging transistors IC13A and IC13B. Temperature compensation of the log converter is by TDR1 which has a temperature coefficient of +0.3%/°C. The log converter itself simply uses the exponential relationship between Vbe and collector current. IC13 is a matched transistor array. The right hand transistor is the logging transistor and its emitter is driven by the input voltage via the left hand transistor which compensates for the logging transistor Vbe. The left hand transistor's collector current is defined by R33 and is held constant by IC3A; its Vbe is therefore constant and so the 8
input voltage at the junction of R36 and TDR1 is impressed across the Vbe of the logging transistor. The logarithmic change in collector current of the logging transistor is converted into a voltage by IC3B. The log converter is actually an antilog converter.
Digital Display VERSION 1 (see note on page 3)
IC1 is an A to D and a frequency counter combined and directly drives the triplexed LCD. Ring counter IC20 andIC21A is incremented each time the display select button is depressed, giving 3 display modes of frequency, amplitude and offset. The frequency mode has 2 methods of measurement; on the 2k to 2M ranges the auto-ranging frequency counter is used and on the 2 to 200Hz ranges the A to D is used to measure the dial voltage Vf. When symmetry is selected IC17B signals the A to D to divide the measured Vf voltage by 10. When IC1 is used as an A to D the decimal point is positioned by IC17D, IC17C and D25 to D28. When IC1 is used as an autoranging frequency counter the decimal point is automatically placed. Some early instruments are fitted with a 40kHz crystal and the frequency doubler IC25 is not fitted and LK4 is fitted instead. When amplitude is selected the A to D measures the voltage on VR11B. When offset is selected the A to D measures the voltage on the output of IC18C. IC14 and IC16A select the voltage to be measured. IC15 and IC16c drive the annunciators by connecting to ANN to turn it on and connecting to BP1 to turn it off. Auto-ranging of the frequency counter occurs at 1999 going up and 180 coming down. If the dial is set to between 1800 and 1999 and the frequency multiplier is then changed or the display select is cycled through, it is possible that one digit of resolution may be lost because of the counter auto-ranging down. To overcome this R25 and C72 delays the counter input, forcing it to always auto-range up. Some of IC1s inputs are dual purpose and are listed below pin 19 - range/freq. In frequency mode this is the counter input. In voltage mode, when pulled high, it divides the measured voltage by 10 (symmetry). When open the measured voltage is displayed. This pin has an internal 5uA pulldown to DGND. pin 24 - freq/volts. When pulled high frequency counting is selected. When open the A to D is selected. This pin has an internal 5uA pulldown to DGND.
pins 20 and 21 are decoded by the IC only in the voltage mode, to place the decimal point.
Digital Display (TG215/TG230) VERSION 2 (see note on page 3)
IC1 is a microcontroller that provides frequency and voltage measurement and displays the results on the LCD. In frequency measurement mode IC14-A outputs the GATE signal, which is controlled via the J (START) and K (STOP) inputs. The GATE is synchronised to the positive edges of the input signal. Whilst GATE is high IC1 counts the internal refer3nce clock, and IC14-B outputs the input signal divided by two, which is also counted by IC1. When GATE goes low the frequency is calculated and displayed. Voltage measurements are made via the A-D inputs RA0 (pin 5), RA1 (pin 6) and RA3 (pin 9). RA0 input measures the amplitude voltage (VA). RA1 input measures the Frequency Dial voltage (VR) which is used to display low frequency measurements. RA3 input measures the offset voltage (VOFT).

(+) Manufacturing Changes (VERSION 1) 1) A few early models were fitted with a 40kHz crystal instead of 80kHz (on the Display PCB Assy). In these models: R25 was 560KJ (23185-4560), IC25 (27226-0701) was omitted and LK4 (231850000) fitted. 2) Prior to Issue 3 main pcbs, VR8 was not fitted and R85 was 15KF (23202-3150). R184 in the TTL output, was not in circuit on pre-issue 3 pcbs.
