Multimeter

HP 3457A has seven functions with 3 1/2 to 6 1/2 digits of resolution extendable to 7 1/2 digits at reading rates from 1 reading every 2 seconds to 1350 rds/s and basic DC volts accuracy as good as 5 ppm.  In addition, the input of the 3457A can be expanded up to ten channels with either of the optional plug-in multiplexer assemblies.  On the bench, the front panel operation is extremely flexible and comprehensive.  In systems, the Hewlett-Packard Interface Bus (HP-IB) is standard.

The 3457A combines superb analog measuring capability with equally powerful measurement management.  More than 1000 readings or whole measurement sequences can be stored in the 3457A for convenient and fast measurement throughput.  The present dmm setup can be stored in the non-volatile state memory for convenient reconfiguration of the dmm.

Additional power from math functions can be obtained by using PASS/FAIL limit testing, NULL, SCALE, THERMISTOR linearization, and others.  The power of total electronic calibration, including AC volts, makes it easy to maintain instrument performance.
