DC and true RMS AC voltage measurements are provided from 0.3 V full scale range with 1 ?V sensitivity up to 300 V. Bandwidth of the true RMS AC converter is from 20Hz to 100kHz on all ranges and up to 300kHz on the 30 V range. Either 2 or 4-wire ohms measurements can be selected with a maximum range of 30 Mohms. Both DC and true RMS AC current capability is provided up to 3 Amps.
One outstanding feature of the HP 3468A meter is the complete calibration is done electronically, either manually from the front-panel of remotely in an automatic calibration system. There are NO INTERNAL ADJUSTMENTS, complete calibration of all functions can be done without removal of covers! HP-IL (simple 2-wire interface) allows for full programmability
