The Agilent/HP 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
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.
- 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
- 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
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 1000:1 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.
