Hewlett Packard 8664A Signal Generator 0.1-3GHz for PARTS/REPAIR. Unit powers on. Display slightly dim. Fan clean and quiet. Unit remains in calibration mode for an extended period (10-15 minutes) warm or cold and will not accept any keystrokes during that time. After all calibration sequences are complete, the display shows : Result Code 2404311 but no error codes. The unit will then accept keystrokes for all data entry and the rotary encoder functions well. Basic signal generator functionality: RF output (attenuator action good), AM internal modulation, FM internal modulation all appear to be O.K. throughout the instrument’s bandwidth. Other repair/maintenance related 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.
