The General Radio 1361-A Oscillator was introduced in Catalog Q (1961) and remained available through Catalog 1973.
The Type 1361-A is a general-purpose, Colpitts-type oscillator covering 450 to 1050 MHz. It can be used to drive bridges, slotted lines, impedance comparators, and as a general purpose signal source.
Direct amplitude modulation at audio frequencies is provided by a front and side panel phone jack and with a 1000-P6 Crystal-Diode Modulator accessory or a 1000-P7 Balanced Modulator.
Sweep frequency operation is provided by the Type 1750-A sweep drive or Type 907-R144 Dial Drive.
The recommended power supply is the Type 1203-B for basic operation, also available were the Type 1264-A Modulating Power Supply or Type 1263-B Amplitude-Regulated Power Supply. The power supply jumper socket must be in place when not in use.
