Applications
The 3325A was widely used in test and measurement labs for signal generation, frequency synthesis, and automated equipment control via GPIB. Common in telecommunications, component testing, and RF/analog circuit development. Compatible with HP test systems and legacy automated test equipment (ATE) platforms.
Condition: Used
This Hewlett-Packard 3325A Synthesizer/Function Generator has been inspected and appears to be in good used condition. The unit includes OPT-001, the High Stability Oven Reference option. The front panel controls, keypad, and LED display appear intact and show normal wear consistent with lab use. The chassis shows light surface scuffing and minor cosmetic wear on the case and rack ears typical of a used benchtop instrument. Rear BNC outputs, the GPIB connector, and power inlet appear undamaged. It has not been powered up or tested at our facility, but was pulled from a working environment. Please view our photo set and contact us if you have any questions.
