Test Signal Trigger Generator. Similar to GE1S/591A but
for Transmitter Group requirements it provides providing
trigger pulses and drive signals for streak test waveform
instead of single phase colour bars. Power requirements

Waveform Generator. Part of SE3L/505. Generates line and
field sawtooth and triangular waveforms, trigger pulses and
blanking pulses. 4U unsupported J width printed circuit
board with panel. Parent equipment SE3L/505. DD 1979.
A.G.C. Sample, Trigger Output and Timing Generator. Under
microprocessor control this provides appropriately times
A.G.C. sample pulses for the UN23/676 and a trigger pulse
for an external waveform monitor. It also provides timing
pulses for LT.S. and noise measurements. It is driven
from the UN16/540 for which it performs address decoding.
Power requirements +5V, +12V, -12V. BMM 4U card. Parent
equipment ME3M/502. DD 1980.
Network Clock Generator. This equipment produces a Network
Logo and an Analogue Clock Display for use in television
presentation. By using electronic pattern generation
techniques it replaces the cameras, slide scanners and
mechanical clocks which were previously required. Inputs
required are standard mixed blanking and synchronising
pulses, a Gent time reference signal (optional) and a logo-
selection signal for remote control. Outputs are 0.7V p-p
RGB plus a composite monochrome output. Power requirements

Address Generator. Address Generator and Multiplexer for
addressing a television picture store organised as two
halves, A and B, of two fields, Wand X. Accepts read and
