HP 5005A SIGNATURE MULTIMETER
The 5005A is a multi-purpose instrument providing 4 character hexadecimal signature analysis as well as various dc voltage, resistance and frequency/time measurements.
The original cost of the 5005A was $2,900 [HP Catalogue 1987]. The 5005B version adds HP-IB programming facility.

This unit is ex-BBC and they used the ITT Cannon XLR-LNE mains connector instead of the CEE22 as standard. Below the mains connector is a 6 pin connector for dc power +5V, GND, +5V, GND, +5V, GND to power logic probes.

The Signature Analyser arrived in very clean condition and looked unused. Application Notes and Technical data sheets were also supplied. A HP Manual was downloaded. Started performance testing and the initial verification tests are ok but the signature analysis requires the HP 5036A Microprocessor Lab
or another instrument with a documented signature analysis.
