- Notes
-
Signal Tracer, Model 703 is essentially a two-transistor transformer coupled amplifier providing adequate gain for signal tracing in the audio stages of a receiver.
Provision is also made by the addition of a diode detector to trace signals in the IF and RF circuits of radio and television receivers.
When used in conjunction with Lab-Craft's radio and television signal probes, models 704 and 705 respectively this instrument provides a complete circuit analyser for fault finding on radio or TV, by tracing the RF and AF signal from aerial to speaker.
The output of this unit is 50 mW and its overall power gain is 50 dB
