34401A Digital Multimeter
The 34401A digital multimeter establishes a new price/performance
standard by offering such features as 6

digits of resolution, 1000
readings per second, and 15 ppm basic dc accuracy at a surprisingly
affordable price. The 34401A has been designed for superior perfor-
mance while providing the flexibility to meet both your present and
future needs.
Great Bench Performance
The clear, logical front panel of the 34401A allows you to easily
select all primary measurement functions. Traditional “bench”
functions, such as continuity and diode test, are included. Math
functions, such as NULL, dB, dBm, limit test, and min/max/avg are
easily selected. A simple menu scheme gives you access to powerful
advanced features, such as the ability to store up to 512 readings in
internal memory. Measurement results are displayed on a bright,
high-visibility readout. A rugged case ensures survival even under
the toughest conditions, and the optional accessory pouch makes it
easy to pack up and go with the 34401A.
Superior Performance in Your System
The 34401A can take up to 1000 readings per second, including
GPIB bus transfer in ASCII format. Both GPIB and RS-232 are
standard, letting you select the interface that best meets your needs.
The 34401A responds to three different command languages. It
accepts SCPI commands (Standard Commands for Programmable
Instruments), which ensures present and future compatibility.
Drivers are also available for both National Instruments Labview
and Agilent’s VEE software.
IntuiLink Software, included with your 34401A, allows you to
transfer your measurement data and images into Microsoft Excel or
Microsoft Word with little or no programming. You can specify the
meter setup and take a single reading or log data to the Excel
spreadsheet in specific time intervals. Programmers can use the
ActiveX components to control the DMM using SCPI commands. To
