The SN-2 is a solid-state uhf wave/dip meter and marker oscillator
The instrument provides continuous tuning from 400 to 1150 MHz. Frequency readout (by the use of a 30-inch steel tape) is better than 1%.
Design features include a battery-operated transistor oscillator in a cavity configuration that is tuned by a precision glass-invar capacitor. The instrument has an outside coupling loop for general use, and a miniature coaxial receptacle for direct connection with 50-ohm coax cable.
The connector assembly can be rotated to obtain variable attenuation (30dB minimum). In addition, special applications are possible with modifications developed by the manufacturer. With a minor adjustment the output of the unit can be increased to function as a local oscillator for UHF mixers. It can also be tracked to an RF circuit, or used as an FM, AM or pulse modulated signal generator, or target transmitter.
