– Manual
The description and ordering information of these accessories are given in chapter XIV of this manual.
The triangle and squarewave generator produces waveforms with a mark-space ratio of 1 : 1.
The frequency of this generator is determined by an input voltage which is connected to an exponential current source.
In position MANUAL of switch SK5, the driving current is determined by the position of frequency control (frequency dial) R1.
In position AUTO of SK5, the input voltage is determined by the output voltage of the sweep generator and the position of R1.
The sweep generator delivers, via potentiometer R3 (SWEEP RANGE) and the control circuit, a triangular voltage wave to the current source in the triangle and squarewave generator, so that the frequency of the latter changes logarithmically. The position of frequency dial R1 determines the central frequency of the sweep.
The frequency of the sweep generator can be varied by means of potentiometer R3, which results in a variable sweep period of the triangle and squarewave generator.
The mark-space ratio of the output voltage wave of the sweep generator can be:
1: 1, giving equal "up" and "down" sweep times
100 : 1, giving a fast "up" sweep speed
1 : 100, giving a fast "down" sweep speed.
The sweep range can be controlled by varying the amplitude of the driving triangular voltage from the sweep generator by means of potentiometer R2.
The single sweep mode provides one single period of the driving triangular voltage, thus producing one complete sweep of the triangle and squarewave generator.
For coupling two or more modular units, refer to chapter XIV.
The instrument may be adjusted to a mains voltage of 100...130 V or 200...260 V by means of switch SK12 on the rear panel. When the instrument is used at a mains voltage of 100...130 V, fuse VL1, having a 500-mA (slow-blow) rating, should be replaced by a 1-A (slow-blow) fuse.
The instrument should be earthed in conformity with the local safety regulations,
The units of the modular system have a semi-floating circuit so that, when several units are coupled, the circuit need only be earthed at one point. Earth currents which may give rise to hum are thus avoided.
Sockets BU8 and BU12 are connected to the metal frame of the cabinet. The signal earth is connected direct to sockets BU7 and BU9, marked \frac{1}{2}, and to the cabinet via a 100-kΩ resistor.
This provides the following output possibilities:
POWER ON (SK1, LA1) Frequency dial (R1) FREQ. Hz (SK6) SWEEP RANGE (R2)
On/off switch with pilot lamp.
Continuous frequency control in position "MANUAL" of SK5.
R1 determines the central frequency of the sweep in position "AUTO" of SK5 (coarse and fine control).
Range selector. The reading of the frequency dial R1 should be multiplied by the setting of SK6.
Potentiometer for adjusting the sweep width. The extreme ends of the sweep can be read from the frequency dial at the points (marked in red around the dial) which coincide with the setting of R2. (Position "AUTO" of SK5).

Two different frequency ranges can be selected by means of switch FREQ. HZ, SK6, viz:
0.1 Hz... 1 kHz (frequency dial reading )
10 Hz...100 kHz (frequency dial reading )
In position "MANUAL" of switch SK5, the frequency can be adjusted by means of frequency dial R1.
In position "AUTO" of SK5 the setting of frequency dial R1 determines the central frequency of the sweep.
The sweep width may be controlled by means of potentiometer "SWEEP RANGE", R2.
The numbers 10 to 1 and 1 to 10 marked on the text plate around the frequency dial correspond to the different positions of R2.
Note: Compare this with the setting of a camera. In this case the reading of the depth of focus depends on the aperture setting.
SWEEP RANGE potentiometer R2 should always be set to such a value that the sweep width does not exceed the upper or lower frequency limit on the frequency dial. In this way a discontinuity of the sweep is avoided.
The period time of the sweep can be adjusted between 10 and 100 seconds by means of potentiometer "SWEEP PERIOD", R3.
In position
In position |/| of SK4 the downward sweep will take almost the whole period time set with R3, "SWEEP PERIOD". The upward sweep time is one hundred times shorter (i.e.: maximum 1 second in position 100 of R3).
In position N of SK4 the upward sweep will take almost the whole period time set with R3, while the downward sweep time is one hundred times shorter.
When switch SK5 is set to position "AUTO" and switch SK3 is set to the upper position, the sweep will continue to its highest frequency end and stop there.
One complete sweep, in the range set by SK6, R1 and R2 and with the speed set by R3 and SK4, will be obtained after depressing button SK2. A second sweep will only be produced after SK2 has been released and is depressed again.
The external generator to be used for sweeping the frequency of the PM 5162, should have a variable d.c. level.
Proceed as follows:
The d.c. level required depends on the output impedance of the external generator.
Sweep range potentiometer R2 serves as an attenuator for the output voltage of this generator. Position 10–10 of R2 gives no attenuation, position 0–0 gives maximum attenuation.
The voltage required at BU5 in position 10–10 of R2 is approx. 12 Vp+p for a full sweep (frequency dial R1 in mid position).
For this instrument four circuit diagrams have been drawn. Fig. 32 gives the overall diagram on which the functional printed wiring boards are shown as mere blocks.
The detail circuits of the printed wiring boards are given separately in Figs. 29, 30 and 31.
Fig. 29 shows the triangle and squarewave generator.
Fig. 30 shows the sweep generator, the sine shaper circuit and the power supply unit.
Figure 31 shows the control circuit.
This circuit has been described in "Electronic Engineering" of June 1967, pages 388–390.
Figure 8 shows a schematic diagram.
The object of the circuit is to produce a triangular waveform at point A, whilst the current I1 may be varied from 2 µA to 20 mA (104), in order to vary the frequency.
A symmetrical triangular waveform can only be obtained when I2 at all times is kept equal to I1.
Assume that switches 1 and 4 are closed as shown in Fig. 8. Main capacitor Cm is discharged with a current 11 and the voltage at A changes linearly in negative direction. This continues until the Schmitt trigger switches to its second stable position. This closes switches 2 and 3 and opens switches 1 and 4.
Now main capacitor Cm is charged with a current l2 and the voltage at point A changes linearly in positive direction until the Schmitt trigger switches again, and so on.
Feedback capacitor Cf serves to keep I2 equal to I1, while I1 is varied over a wide range.
Fig. 8. Block diagram of triangle and squarewave generator
Cf is charged with a current I2 when Cm is discharged with a current I1. Cf is discharged with a current I1 when Cm is charged with a current I2. When I1 = I2 and Cf = Cm the two capacitors are charged to the same voltage but with a phase shift of 180°.
If the voltage at point A is applied to the other side of Cf, the voltage at point B remains constant.
However, consider I2 > I1; the voltage at point B then goes positive and also the base potential of TS11 via buffer TS14 and feedback amplifier TS12–TS13, hence I2 will be reduced.
Compensation takes place until I2 = I1. When on the other hand I1 is varied in order to sweep the frequency, I2 also changes thus maintaining a 1 : 1 mark space ratio of the output voltage.
The main capacitors are C11 and C12, the feedback capacitors are C6 and C8.
In position ×1 of selector SK6 only C12 and C8 are in circuit.
In position ×0.01 of SK6 contacts 34 and 26 as well as contacts 30 and 25 are short-circuited to bring C11 in parallel with C12 and C6 in parallel with C8, thus increasing the value of the main capacitor and the feedback capacitor. The frequency of the generator now has decreased one hundred times.
The buffer stages form very high impedances and are important because, when the switched current is only 2 µA, only a very small amount is sub-tracted.
The voltage on the main capacitor(s) is applied firstly to the feedback capacitor(s) via buffer stage TS31–TS33. Select-on-test capacitors C7 and C9 serve to compensate the feedback capacitance for the losses in this buffer stage.
The voltage on the feedback capacitors is applied via buffer stage TS14 to the feedback amplifier.
Secondly the triangular voltage on the main capacitor(s) is fed to Schmitt trigger TS34-TS35 via buffer stage TS30-TS32. After this buffer stage the triangular waveform is connected to output socket BU2 via contact 23, to output selector SK7 and to the sine shaper network (CD4, contact 23).
The feedback amplifier consists of the symmetrical arrangement of TS12 and TS13, giving a gain of 1.
A voltage rise on the base of TS13 causes a voltage rise on the collector of TS12, thus reducing the current (I2, Fig. 8) through TS11.
The Schmitt trigger circuit TS34–TS35 is connected to three constant current sources, viz: TS36, TS37 and TS38, the bases of which are interconnected. Diode GR19 serves for temperature compensation of the emitter-base voltages of these three transistors.
Assume that TS34 is conducting and TS35 is cut off. Through R72//R73 and R74 passes a current l1 (from source TS36) plus a current l2 (from source TS37).
Through resistors R78//R79 passes a current l3 (from source TS38). When TS34 is cut off and TS35 is conducting, only current I2 flows through R72//R73 and R74, while a current l1 + l3 flows through resistors R78//R79. Currents I1 and I2 and resistors R72, R73, R74 and R83 determine the amplitude of the squarewave arising on the collector of TS34.
Because this amplitude directly determines the frequency of the triangle, for R72–R73–R78–R79–R82–R83–R85–R87 accurate metal-film resistors have been chosen.
Two anti-phase squarewaves which are positive with respect to earth and two which are negative with respect to earth, are used for driving the "switches" TS20...TS27.
The squarewave voltage on the base of TS35 has the same amplitude as the triangle voltage on the base of TS34.
Capacitor C15 serves to compensate the frequency response at high frequencies. The squarewave voltage on the collector of TS35 is, via emitter followers TS39–TS40 and contact 32, applied to output socket BU3 and output selector SK7.
The exponential current source consists of a network of diodes and resistors. The biasing of the diodes and the values of the resistors have been selected so that the application of a linearly changing voltage produces an exponential current through the network.
Assume that a current I flows through the network. An increase of 0.5 Volt on the anodes of the diodes causes the current to increase approx. with a factor e (2.718). The current then is 2.718 1.
An increase of 5 V on the anodes of the diodes thus gives a current of . When the initial current the current now is .
The required current variation for a frequency sweep of 1 : 104 is from 2 µA to 20 mA. This current variation thus is obtained by a voltage change of slightly less than 5 V.
The bias voltage across resistor chain R108...R125 is kept constant by means of zener diode GR12.
Circuit TS28, TS29 is a low impedance source which supplies the current through resistor chain R108...R125 and zener diode GR12, while keeping the voltage at junction R125–GR38 constant.
The sweep voltage from an external source or from the sweep generator and/or the voltage from frequency determining potentiometer R1 is applied to the symmetrical circuit consisting of TS15'-TS16 and TS15"-TS18 via contact 13. The same voltage as is applied to the base of TS15 will appear on the base of TS15" and thus on the anodes of the diodes of the exponential current source.
The object of the sweep generator is to deliver a triangular waveform which may be
Moreover, the sweep generator can be made to deliver only one period on pressing a button (single sweep).
A schematic diagram is shown in Fig. 9.
The triangle wave is produced by an operational integrator with a bistable multivibrator in the feed-back loop.
The integrator amplifier consists of transistors TS45, TS46, TS47, TS48 and TS49. The feedback capacitors are C20, C21 and C22.
Fig. 9. Block diagram of sweep generator
Assume that a positive input voltage is applied via contact 3. This causes a negative going voltage on the emitter of TS49. The negative ramp is applied via contact 6, contact 5 (SK3 in position CONTINUOUS), GR52, R142 and R144 to the base of TS51.
At a certain value of this voltage the multivibrator TS51, TS52 will switch over such that TS51 is cut off and TS52 is conducting. The collector voltage of TS52, which is about zero volts, now is applied to contact 3 via contact 31 and sweep period potentiometer R3. This causes a positive going voltage on the emitter of TS49. This positive signal now is applied to teh base of TS51 via emitter follower TS50, diode GR51 and resistors R141 and R144.
At a certain value of this voltage the multivibrator TS51, TS52 will switch over again and the positive voltage on the collector of TS52 now again is applied to the integrator input via contact 31, sweep period potentiometer R3 and contact 3.
By changing the current through resistor R130 of the integrator amplifier by means of sweep period potentiometer R3, the slope of the triangular waveform and thus the frequency of the sweep voltage is altered.
The squarewave voltage from bistable multivibrator TS51, TS52 is also applied to sweep mode switch SK4 via contact 31.
In the top position of SK4, diode GR70 and resistor R215 are switched in parallel with the integrator input resistor R130. The positive half-period will now cause a greater charging current of the integrator capacitors, resulting in an increased slope of the negative going ramp of the triangle. In the bottom position of SK4 the chain GR70, R215 is reversely connected so that now the second half-period of the squarewave voltage causes a greater charging current of the integrator capacitors, resulting in an increased slope of the positive going ramp of the triangle.
When SK3 is set to its upper position the short-circuit between contacts 5 and 6 is broken. The negative going ramp of the integrator now will fail to switch over the bistable and the integrator will stop.
Pressing single shot button SK2 connects the —30 V supply voltage to contact 5 via capacitor C50. The bistable now switches over. First a positive going ramp and then a negative going ramp will appear on the emitter of TS49. Then the integrator will stop again. Thus only one cycle is produced.
The sweep voltage is taken from the integrator output via contact 6 and is applied to sweep range potentiometer R2 via points 16 and 15 of the control circuit board.
The sweep voltage which corresponds to the logarithm of the frequency may be taken from BU4.
The object of this circuit is to connect the sweep voltage (internal or external) to the exponential current source in the triangle and squarewave generator and to ensure that the sweep will take place around the central frequency set by potentiometer R1 and with the sweep width set by potentiometer R2.
The control circuit consists of operational amplifier TS1...TS4 and of d.c.-shift circuit TS5...TS7.
A schematic diagram is shown in Fig. 10a. In position MANUAL of SK5 potentiometer R1 is connected to the voltage between points 3 and 4 of the control circuit board.
Fig. 10a. Block diagrams of control circuit
The voltage range of R1 is then from -20 to -25 V. The voltage from R1 now is connected to contact 13 of the triangle and square wave generator board, thus determining directly the output frequency.
In position AUTO of SK5, R1 is connected to the voltage between points 2 and 5 of the control circuit board. The voltage range of R1 then is from ------------------------------------
The voltage of R1 is now only applied to the base of TS2 via point 8, while the sweep voltage from potentiometer R2 is applied to the base of TS1 via point 10 of the control circuit board.
First assume that frequency control potentiometer R1 is set to its midposition (1K) and sweep range potentiometer R2 to position 0-0. See schematic diagram Fig. 10b.
The voltage on both inputs of the operational amplifier TS1...TS4 is 0 V. The voltage on the amplifier output (the emitter of TS4) is also 0 V. Circuit TS5...TS7 gives a constant d.c. shift of -22.5 V. Thus the voltage on point 11 of the control circuit board and on contact 13 of the triangle and square wave generator board is -22.5 V, which corresponds to the voltage on the same point in position MANUAL of SK5 and midposition of R1.
Now assume that sweep range potentiometer R2 is set to position 10–10 (see Fig. 10c).
The amplitude of the sweep voltage on the cursor of R2 is from -2.5 to +2.5 V.
A voltage of +2.5 V on one input of the operational amplifier and a voltage of 0 V on the other input gives an output voltage of -2.5 V. The output voltage applied to the triangle and squarewave generator after the d.c.-shift circuit now is: -2.5 -22.5 = -25 V.
This corresponds to the lower limit of frequency potentiometer RI in position MANUAL of SK5, see Fig. 10c.
A voltage of -2.5 V on one input and a voltage of 0 V on the other input of the operational amplifier gives an output voltage after the d.c.-shift network of -20 V, which corresponds to the upper limit of frequency potentiometer R1 in position MANUAL of SK5, see Fig. 10d.
Finally consider that R1 is set to a position half-way between the mid position (10 K) and the upper position and R2 is set to position 5–5.
The voltage on the cursor of R1 now is 1.25/2 V. The amplitude of the sweep voltage on the cursor of R2 is from -1.25 to +1.25 V.
A voltage of +1.25 V on one input and a voltage of +1.25/2 V on the other input gives an output voltage of the operational amplifier of 0 V. After the d.c-shift circuit the output voltage is -22.5 V, which corresponds to position 1K of frequency potentiometer R1 in position MANUAL of SK5, see Fig. 10e.
Fig. 10e
Fig. 10f
A voltage of —1.25 V and a voltage of +1.25/2 V on the inputs gives an output voltage of the operational amplifier of +2.5 V.
After d.c.-shift the output to the exponential current source is +2.5 -22.5 - -20 V which corresponds to position 100 K of frequency potentiometer R1 in position MANUAL of SK5, see Fig. 10f.
When SK3 is set tot the upper position (SINGLE) the integrator amplifier of the sweep generator will saturate after its negative going ramp. This is described in section C, paragraph SINGLE SWEEP. In position AUTO of SK5 the output voltage from the sweep generator now causes the frequency sweep to remain at its high frequency end, set by frequency dial R1 and sweep range potentiometer R2.
Short-circuiting input socket BU5 to earth has the same effect as turning R2 to position 0-0 (voltage on the cursor of R2 is 0 V). This means that when a low impedance source of 0 V is connected to BU5 the frequency sweep will return to its central frequency set by R1
Sweeping may now be effected by means of a voltage from this low impedance source, R2 serving as an attenuator for this voltage.
Position 0–0 gives maximum attenuation and position 10–10 minimum attenuation.
This circuit basically consists of a network of diodes and resistors in the form of an integrated circuit (U1).
The application of a linearly changing voltage produces a sinusoidal current through the network.
Assume that two anti-phase triangle waveforms are applied to the bases of long-tailed pair TS57, TS59. The waveform to TS59 is taken directly from the triangle output of the triangle and squarewave generator (contacts 23 of both boards).
The waveform to TS57 is phase-inverted by operational amplifier TS53...TS56. On the common emitter of the long-tailed pair a triangle wave appears which has twice the frequency of the input signal on contact 23.
This double frequency triangle is applied to the diode network thus producing the sinusoidal current through the network and through TS57 and TS59. However only one of the transistors of the pair is conducting at a time, hence on each collector a half-wave rectified sinewave is present.
These two waves are combined by applying them to the bases of longtailed pair TS61, TS63.
The sinusoidal voltage is taken from the collector of TS61 and fed to output socket BU1 via emitter follower TS64 and contact 14. The sine wave voltage is applied to output selector SK7 via contact 12.
By means of SK7 one of the three output waveforms can be chosen. The selected waveform is applied to socket BU6 via amplitude control R4 and emitter follower TS8 on the control circuit board.
The a.c. voltages from supply transformer T1 are rectified by bridge circuits GR60 and GR61.
The output voltages of -30 V and +30 V are stabilised by comparing them via an amplifier (TS74, TS76 and TS75, TS77 resp.) with a reference voltage (GR64 and GR65 resp.) and using the difference to control the current through the series regulator (TS81 and TS80 resp.). Amplification of the regulating current takes place via transistors TS72 and TS73 resp.
The top plate can be removed after loosening the fastener at the rear of the instrument.
To refit the top plate, place the groove of the fastener in the horizontal position and push the cover home.
The side plates can be taken off after removing the screw on each side of the instrument.
The bottom plate can be removed after loosening the appropriate screws at the rear of the cabinet.
This strip can be removed by pushing the two nylon slides "A" in the direction indicated in Fig. 11.
In order to pull out the plug-in printed wiring boards, they should first be slightly bent at the top side.

For optimum performance the instrument should be adjusted at the temperature at which it will be used.
The adjusting elements and the auxiliary equipment required for the adjusting procedure are indicated in chapter X.
The circuit should be earthed by connecting BU7 to BU8. All test equipment should be earthed via the instrument under test.
Accurate checking and adjusting of the frequency and the distortion according to sections E, F and J is only possible when the covers are fitted on the instrument and after a warming up period of at least one hour.
When the instrument is far out of adjustment, first carry out the adjustment with the top cover removed. Then accurate checking and readjusting can take place with the top cover fitted.
Connect the instrument to the mains and check that the current consumption does not exceed 200 mA at 230 V mains or 400 mA at 115 V mains.
- Set the controls as follows: | |
---|---|
SK3 (SINGLE) | CONTINUOUS |
SK4 (MODE) | centre position |
SK5 (MAN/AUTO) | MANUAL |
SK6 (FREQ. Hz) | range ×1 |
SK7 | triangle output |
R2 (SWEEP RANGE) | position 0–0 |
R3 (PERIODS SECS) | position 100 |
R4 (AMPLITUDE) | position 3V |
Fig. 13. Distortion adjustment
Adjust R81, R164 and R167 until this output appears.
Adjust R174 until the waveform is about 0 V.
Adjust R81 until the output is symmetrical.
Adjust R167 until the peaks have just lost their triangular properties.
Adjust R164 until a pure sinewave is obtained.
Check that the output voltage at socket BU4 is from +6 V ± 10% to -6 V ± 10%.
- Check that the squarewave voltage on socket BU3 meets the following requirements:
amplitude | 10 V p-p + 1 V p-p |
---|---|
rise time | < 100 ns |
overshoot | < 2% of maximum output |
For example: After adjustment of R164 and R81 the distortion is D1.
Move R167 and the distortion will become D2 (D2 > D1).
Optimise R164 and R81 and the distortion will become D3 (D3 < D1).
If D3 > D1, R167 should be moved in the opposite direction.
If a distortion of less than 0.5% cannot be obtained select another value for select-on-test capacitor C9. See chapter XII, sections B. 4 and C.
To facilitate fault finding some d.c. voltages and waveforms present at various places in the circuit have been indicated in the circuit diagrams. The voltage levels given merely serve as a guide.
The circuit of the triangle and squarewave generator forms a closed loop, which complicates tracing a fault on this board.
To facilitate fault finding on the triangle and squarewave generator board several transistors at vital places in the circuit have been mounted on sockets. They can be easily plugged in and taken out of the board without soldering. Moreover a fault finding procedure for this board has been given in section B of this chapter.
When replacing parts, switch off the instrument. After replacing parts it may be necessary to readjust the instrument according to chapter XI.
A fault on the triangle and squarewave generator board can result in:
In each case first check the supply voltages to be +30 V and --30 V.
If the triangle and sinewave outputs are present but no squarewave output, transistor TS40 or possible TS39 is defective.
If no squarewave output and no triangle output and hence no sinewave output is available or if no proper waveforms can be obtained by adjusting R51, it is recommended to follow the procedure below.
A deterioriation of the upward slope of the triangle may be caused by a fault in the feedback system (TS31, TS33 and capacitors C6...C9) or by a faulty TS30 or TS31.
A deterioriation of the downward slope may originate from a fault in the current source including TS15...TS19 or from defective field effect transistors TS30 and TS31.
If the triangle shape is correct but there is still a high distortion of the sinewave not caused by the sine shaper board, this distortion is caused by an asymmetry or amplitude variation of the triangle wave.
Probable cause: incorrect value of select-on-test capacitor C15.

Power amplifier PM 5162 is part of the modular L.F. system, which consists of various units, which can be easily linked, thus forming several alternative L.F. systems for a wide field of applications. (Refer to PHILIPS publication: "Instrument and Application"). The width of the various units is expressed in modules, one module having the following dimensions:
width: | 70 mm |
---|---|
height: | 178 mm |
depth: | 250 mm |
The units have a width of one, two or three modules. They can be linked to a maximum width of six modules.
The instruments are suitable for rack-mounting.
The following units are, amongst others, suitable for use with the PM5162.

For coupling the various units to form one complete instrument, coupling accessories are available for every chosen combination up to a width of six modules.
These accessories comprise one coupling kit and five different cover kits. With the aid of the parts provided in the coupling kit any two modular units can be linked to each other.
A cover kit contains a top cover, a tilting assembly and an extension piece for the carrying handle; with these parts the coupled units can be equipped to form one complete instrument.
One coupling kit PM 9500 should be ordered for each coupling connection to be made. Depending on the total width of the coupled units, one of the following cover kits should also be ordered.
Type number | Cover kit for a total width of |
---|---|
PM 9502 | 2 modules |
PM 9503 | 3 modules |
PM 9504 | 4 modules |
PM 9505 | 5 modules |

To be coupled | one 2-module unit |

two 1-module units | |
Required coupling accessories | two coupling kits PM 9500 |
one cover kit PM 9504 |
When an equipment is to be made up from 1-module units only, coupling parts additional to the coupling kit and cover kit are required.
This is because 1-module units are not equipped with a carrying handle. These additional parts are:
