Additional Features:

• DC volts accuracy as good as 5 ppm.
• Input of the Agilent 3457A can be expanded up to ten channels with either of the optional plug-in multiplexer assemblies (sold separately).
• Measures DC Volts & Current, Resistance, True RMS AC Volts & Current, Frequency & Period.
• Also performs the following math functions: Null, Scale, Offset, RMS Filter, Single Pole Filter, Thermistor

The Agilent 3457A is a Multimeter that 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 per every 2 seconds to 1350 readings per second. In addition, the input of the HP 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.

Powerful Measurement Management

The unit combines superb analog measuring capability with equally powerful measurement management. More than 1000 readings or whole measurement sequences can be stored in the unit 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 ea to maintain instrument performance.

System Features

Keeping with HP's long tradition of systems-oriented digital multi-meters, this instrument has all the systems features you've come to expect plus more to make interfacing to your computer even easier. Features like: flexible formatting of ASCII, 16-bit binary, or 32-bit binary data and buffer memory so that you can take measurements with the meter at its highest speed. You also find voltmeter complete output and external trigger input signals ideal for synchronizing other instrumentation. Finally, programmable front-rear terminal switching lets you measure two separate inputs without a scanner.
