The range with the multiplier is from 10,000 uHz to 1,011.11 kHz. The output amplitude is 3 digits and a multiplier. The MS 1 to 10 and the LS 2 from 0 to 9. The range is from 1.00 mv to 10.11 volts. There are VCO and SYNC inputs, a SYNC output, and a 50 ohm signal output BNC on the back of the instrument.
All controls have a remote input setting.
There is a connector on the back which I assume is for digital control lines not RS232.
