GSG-122 AM/FM Stereo Synthesized Signal Generator |
These programmable AM/FM synthesized RF signal generators feature user friendly keypad control of RF frequency, output level and modulation. Up to 100 different test conditions can be stored in internal memory for easy retrieval and greatly cut down setup time. The front panel has four bright LED displays simultaneously displaying RF frequency (6 digits), RF output (2 digits), modulation (3 digits) and memory (2 digits). A phase locked loop synthesizer ensures extremely stable frequency outputs. It is ideal for communication industries, AM/FM receiver and 2-way radio transceiver service. SG-122 is also used for FM stereo modulation.
