HP 8657B 2.060 GHz with stable oscillator option

Great flagship signal generator from HP.
Reliable and accurate test equipment a must for radio calibration, testing and repair.
this unit is in a very good condition and is calibrated. It also has the High Stable Oscillator option installed. 
Frequency Range is 100kHZ up to 2.060 GHz, fully operational accross the span.

Signal generators of this level and quality are easily north of $3k.

Check, test and calibtrate the deviation on your rigs, tune up your recivever sensitivity and frequency dependant devices.
A must for any sevice bench and will be supplied with a manual.
I have videos to share with serious buyers showing actual calibration checks on the unit, including the High Stability Oscillator against GPS alligned frequency counters. Please send me a message and I will send the videos taken yesterday.
The unit does have the expected cosmetic wear and tear but is 100% electrically sound unit Reason for selling is that the unit is not getting much use lately and collecting dust. therefore looking for a good home.????
