General Radio 1220-A

unit klystron oscillator General Radio 1220-A Unit Klystron Oscillator Available from 1956 to 1965 Manuals General Radio 1220-A Klystron Oscillator Manual 932-B 1959 (All manuals in PDF format unless noted otherwise)

The General Radio 1220-A Unit Klystron Oscillator was introduced in 1956 Catalog O and remained available through Catalog S 1965.

Frequency Range: Depends upon klystron tube used (refer to table below).
Modulation Internal: Internal 1 kHz square wave, adjustable within +15 Hz.
Modulation External: External square wave, 50 Hz to 200 kHz; sine or square-wave modulating signal of at least 15 V rms required.
Modulation FM: at least 15 MHz excursion obtainable with less than 3 dB change in output; at 60 Hz, on rms input of about 10 V is suitable.
