Applications

Counter and timing boards with TCXO oscillators were used in precision measurement and test equipment, telecommunications systems, and industrial control applications requiring stable frequency references. This board was integrated into the Keithley 7500-XC-001 measurement system, a modular platform used in laboratory and field test environments through the 1990s and 2000s.

Condition: Used
This Keithley PC7422 PCIP-CNTR Counter/TCXO ISA board has been inspected and is in good condition. It was pulled from a Keithley 7500-XC-001 Metrabyte Computer that was in active use and functional at the time of removal. The board shows normal light wear consistent with bench use. PCB traces, components, and the rear-bracket connectors (BNC and DB9) all appear clean and undamaged. Please view our photo set and contact us if you have any questions.
