Agilent / HP / Keysight 3457A
3457A Digital Multimeter
Description
This unit 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, and DC volts accuracy as good as 5 ppm.
In addition, the input of this unit 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.
This unit 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.
