Agilent / HP 1120A
Active Probe
Description
This unit is a IEEE/GPIB translator for a number of fluke products, including universal counter/timers, communications counters, digital thermometers, frequency synthesizers, and digital AC voltmeters.
Up to 3 instruments can be interfaced to the bus with this single unit.
It can operate between one or more instruments and the IEEE bus, it converts codes and signals on the bus to corresponding codes and signal compatible with the particular instrument
