The PM 3226 uses two separate electronically switched vertical deflection channels A and B to prove
channels are identical, only the A channel

attenuator, an input stage, a preamplifier and a switched amplifier to a combined output amplifier that
tube. The individual stages of the vertical deflection system are now
the Y deflection plates of the cathode-ray
described in some detail with reference to the overall circuit diagram (Fig. 3.39).
By means of the front-panel pushbutton 861/2 (AC/DC) the input signal is applied either via capacitor 241 or
direct. Pushbutton 861/3 (0) isolates the Y input signal and earths the channel input for reference purposes;
e.g. for calibration or centring the trace.
The overall attenuation of the stage is determined by the combination of the selected sections of both voltage
dividers. The various combinations are selected by the 12 positions of the front-panel AMPL/DIV attenuator
switch 862.
The first divider stage incorporates a through-switching position, and two resistance-capacity pi-networks that
attenuate by factors of x2.5 and x5. The second divider stage also incorporates a through-switching position,
and three resistance-capacity pi-networks that attenuate by factors of x10, x100, x1000. In combination, the
two step-attenuator stages provide twelve Y deflection coefficients from 2 mV/div to 10 V/div in a 2-5-10
sequence.
66
Equalisation of the input capacitance for the five attenuator networks is achieved by trimmers 243, 248, 252,
257 and 262.
The voltage divider sections are made independent of the input frequency range of the oscilloscope (15 MHz) .
by means of trimmers 246, 251, 252, 256 and 261.
Vertical movement of the trace is provided by front-panel Y POSITION potentiometer 436 connected to the
gate of field-effect transistor 31/2. Preset potentiometer 446 serves to adjust the range of the POSITION :
potentiometer 436 to compensate for differences in the field-effect characteristics of 31/1 and 31/2. In
addition, these transistors share the same integrated circuit block to aid stabilisation.
3.7.1.3. Preamplifier
Note: Transistors forming part of integrated circuits are referred to by their collector points.
The balanced preamplifier stage, formed by transistors 32/1, 32/2, 32/3, 32/4, 33 and 34 is of the series-shunt
feedback type. Since both halves of the amplifier are contained in the same integrated circuit block, the gain is
independent of frequency and drift; i.e. two signals in the same phase cancel out. The Darlington pair input
stages are fed from a constant-current source transistor 32/5 and direct coupling is employed throughout.
The voltage gain at the 33, 34 collectors is independent of the active components and is approximately equal to
the ratio of the feedback resistance to the emitter resistance; ,

Most of the amplifier stages used in the PM 3226 are amplifiers with series and shunt feedback (Cherry-Hooper).
A typical example of such an amplifier is shown below.

3.1.3. Triggering
The trigger source switches for triggering the time-base generator can select any of the following input sources:
— an internal signal from the vertical A channel
— an internal signal from the vertical B channel
— an external signal from the front-panel socket via the X and trigger preamplifier
a signal derived from the mains supply.

Source selection is achieved by means of pushbutton switches 861/8 (A), 861/9 (B), and 861/10 (EXT).
Simultaneous selection of A and B (LINE) provides triggering from the mains supply utilising an internal source.
If TV is selected (861/12 depressed), a peak detector and sync separator stage facilitate triggering from TV fine
and frame signals. The peak detector is also switched into circuit when the LEVEL control is in the TOP
position. Sources applied to the front-panel TRIG or X EXT socket can be used for either triggering or

of a balanced
As can be seen from the simplified diagram, Fig. 3.10. the LEVEL control lies at the midpoint
potential divider network between +12 V and —12 V. The wiper can swing nominally between +4 V and —4 V.
In the NORMAL/TOP mode, a +12 V supply via the TOP switch is fed to the base of the switching transistor
73/4, thus causing it to conduct. As a result, the peak detector diode 157, diode 158, cap. 353, cap. 354 and
resistor 633 is activated, which clamps the base of transistor 74 to conduct on signal peaks. In this mode, the
emitter of 74 is biased by voltage divider resistor 642 and resistor 643 between the —12 V supply and the Ov
rail via the switching diodes 163 and 164.
In the TV mode, the switching transistor 73/4 conducts to provide peak-detection of the synchronising pulses
of a video signal. To achieve this, a+12 V supply is fed via the TV/NORMAL switch 861/12 and diode 156 to
the base of switching transistor 73/4. In this mode, the emitter of transistor 74 is biased via the switching
diodes 161 and 162 from a preset potentiometer 651 which provides the appropriate TV trigger adjustment.
The amplified signal at the collector of 74 is matched to the pulse shaper circuit by means of emitter-follower
77. The amplified level of the signal is such that it exceeds the hysteresis gap of the Schmitt trigger pulse
shaper formed by 91/1 and 91/2 (see Fig. 3.11). In this way, switchover of the Schmitt trigger occurs on both
positive and negative-going excursions of the input trigger signal and the fast switching action results in square
wave outputs.
The trigger pulse shaper consists of transistors 91/1 and 91/2 in Schmitt trigger configuration. This pulse shaper
circuit transforms the emitter output voltage of emitter-follower 77 into a square-wave voltage of constant
amplitude and width, having the same frequency as its input signal. Inset Fig.3.11 shows how the output signal
is applied.
From this figure it is evident that the input signal should be of sufficient magnitude to exceed both limits of
the hysteresis gap (switchover points) in order to obtain a square-wave output voltage.

CIRCUIT: CIRCUIT
Before considering these stages in detail, the general principle is briefly described. Basically, the sweep-gating
multivibrator, under the control of trigger pulses from the differentiator and also feedback pulses from the
hold-off circuit, supplies square-wave pulses to the switching transistor 94 of the sawtooth generator.
The time-base capacitors (effectively in parallel with the switching transistor) are charged linearly through a
constant-current source to provide the forward sweep, and are discharged rapidly by the switching transistor
to provide the flyback period. The resulting sawtooth output is taken from two transistors in Darlington pair
configuration and fed to the X-final amplifier.
73
When this input voltage reaches a pre-determined level, the sweep-gating multivibrator switches over. In this
condition, transistor 91/4 is cut off. Switching transistor 94 then starts to conduct and the time-base capacitance
is discharged via this transistor.
On arrival of the next trigger pulse this cycle is repeated.
The magnitude of the charging current of the time base capacitors, and thus the time coefficient, is determined
by resistors 831 to 841. Preset potentiometers 746 and 748 permit adjustment of the time coefficients in the
ranges 200 ms/div to 0.5 ms/div, and the range 0.2 ms/div to 0.5 us/div respectively, by controlling the base
current of transistor 92.
Timebase capacitor 377 is switched into the circuit by means of transistor 95 which is switched by a positive
voltage applied to its base in certain positions of the TIME/DIV switch.
Blanking pulses are provided by the collector circuit of 91/4 via 716 and capacitor 321 for the beam blanking
stage. In addition, a rectified output is provided via 176 for the front-pane! PROBE ADJUST socket.
The practical gain value obtained is slightly lower than the theoretical gain.
When the front-panel X-MAGN switch is operative for 5 times magnification, the series-feedback resistance is
shunted by resistor 669 thus reducing its value by a factor of five.
Consequently, the gain of the stage is correspondingly increased by the same factor. Capacitors 360 and 361
across the feedback resistors 683 and 687 respectively provide high frequency compensation.
