This sale for is a Gigatronics 7000 Synthesized RF Signal Generator covering the range from 10 MHz to 26.5 GHz. The output can be controlled from -20 dBm to +15 dBm. It is in nice physical condition with the minor exceptions noted below. It seems to be in good operating condition. The ON/OFF switch was intermittent and I replaced it with a C&K toggle switch, see photo. The OFF pushbutton  cap was missing and I replaced it with one that is close and which looks like it belongs, see the same photo as the ON/OFF switch.  The ON/OFF switch was replaced using a custom milled metal plate to fill the rectangular hole, without modifying the front panel, and the old switch is included in case an original is found. The output power was measured over as wide a range as my HP436A power meter covers and the frequency accuracy was measured over the range that my EIP575 frequency counter covers, see photos. Note that this was all done from turn-on in about 30 minutes (minimal warm up) and an SMA/Type-N adapter was used which would have a slight effect on the power measurements at high frequencies. The frequency stepping and selections (number of steps, frequency step, start frequency, etc) worked. Any power meters, frequency counters, and cables show in the pictures are NOT included. They are to show the signal generator works. Spot checks with 0dBm selected gave: 50 MHz                 +0.03 dBm 100 MHz               +0.06 dBm 1 GHz                    +0.14 dBm 5 GHz                    +0.06 dBm 10 GHz                  +0.17 dBm 18 GHz                  - 0.01 dBm 25 GHz                  -0.97 dBm  (outside the range of the HP436A detector) +10 dBm at 10 GHz gave +9.95 dBm Frequency checks gave: 1 GHz                    1,000,008,376 5 GHz                    5,000,042,501 10 GHz                  10,000,082,786 18 GHz                  18,000,141,455
