Hewlett Packard 8665B Synthesized Signal Generator for PARTS/REPAIR

Hewlett Packard 8665B Synthesized Signal Generator for PARTS/REPAIR. Unit powers on, shows no error codes and completes calibration sequence. Display is only slightly dim (usually these VFD’s are very dim or unusable), fan is clean and quiet. When generating on any frequency, the unit will intermittently drop by 20 or 40dB ish. This is made worse by tapping or gently slapping the unit on the right side and can be temporarily restored by adjusting the attenuator stage through the entire range and back to desired level. AM/FM modulation and internal audio appear to function O.K. No further testing performed. Other issues may be present. This item will require an oversized box and extra packing to avoid possible transit damage. Shipping cost may be high. In person pick up or arrange your own transportation is preferred. As shown.
