Special Features:

Opt 520 is 250khz to 20ghz; cw resolution 0.001hz; sweep mode resolution 0.01hz; internal timebase reference oscillator; 10mhz reference output

Properties:

An instrument which produces a continuous audio and/or radio frequency voltage, and which is designed for test purposes only. It may provide an output at one or more fixed frequencies or be continuously variable over one or more bands. The fixed frequency type is distinguished from calibrator, frequency in that it is a voltage source and is not primarily intended for checking frequencies from other sources. Excludes generator, interference.
