Welcome to
Azur Electronics
RF Output on the N-type connector and FM Input on the BNC connector. The FM Input can also be used for a phase lock signal. AM can be provided via a BNC on the 8620C Rear Panel. Option 002 adds a programmable 70dB attenuator which also adds a front panel switch for 10dB attenuation steps.
Frequency Reference Output provides 1V/GHz ramp signal or 10mV to 1.3V over the frequency range 10MHz to 1.3GHz. Interface connector to 8620C Sweep Oscillator, P1 36 way Amphenol 'Blue' Plug. Option 004 moves the RF Output to the rear panel.
I haven't found an option which moves the FM Input to the rear panel, but there is obviously a provision for this.
