   The Agilent/HP 3457A combines superb analog measuring capability with equally powerful measurement management.  More than 21 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.

System Features

   Keeping with Agilent/HP's long tradition of systems oriented digital multimeters, the 3457A 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 3457A at its highest speed.  In addition, you'll find the VOLTMETER COMPLETE output and EXTERNAL TRIGGER input signals ideal for synchronizing other instrumentation with the 3457A.  Finally, programmable front-rear terminal switching lets you measure two separate inputs without a scanner.

Features
  • DC volts accuracy as good as 5 ppm.
  • Input of the HP 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 Linearization, dB, dBm, % Error, Pass/Fail Limit Testing, and Statistics.

Three Rear Panel Plug-In Options

   Either one of three different optional assemblies may be used with the 3457A for different measurement capabilities.  Using the multiplexer assemblies with enable up to ten signal channels to be scanned either sequentially or randomly. 

   For measurement flexibility, the 44491A Armature Relay Multiplexer Assembly offers eight two-wire channels and two current/actuator channels.  Under software control, the eight two-wire channels can be reconfigured to four 4-wire ohm channels.  The two current channels offer automatic make-before-break switching so that the path for current as high as 1.5 A is never broken.

   For higher speed scanning, the 44492A Reed Relay Multiplexer Assembly offers ten two-wire channels.  The 44492A is useful for switching DCV, ACV, AC+DCV, two wire ohms, frequency and period measurement signals with a maximum amplitude of 125 V.  The Reed Relay Multiplexer can close a relay and make a measurement at a maximum rate of 300 channels per second.

   For measurement of voltages up to 1414 V peak, the 44497A High Voltage Assembly offers a 21:1 attenuator input (channel 1) for the high voltage measurements.  In addition, the other rear terminal input (channel 0) can be utilized to perform conventional VDC, VAC, Two-wire and Four-wire Ohms, Period, Frequency, DCI, and ACI measurements.
