Introduction - Tektronix DMM4040 User Manual

Introduction

The DMM4040 and DMM4050 are 6-1/2 digit, dual-display multimeters designed for
bench-top, field service, and system applications. Their full complement of measurement
functions plus its RS-232, IEEE 488, and Ethernet Remote Interfaces makes these
multimeters ideal candidates for precision manual measurements and use in automated
systems. For portability, these multimeters include a carrying handle that also serves as a
bail for bench top operation.
There are a few feature differences between these two multimeters, and some
specifications are tighter for the DMM4050. Features that exist in only one multimeter
will be identified with the addition of "4050 Only" by each feature that is found only in
that model. Separate specification tables are also used to clarify the differences between
these two models.
The following is a list of some of the features and functions:
Bright, large-digit, wide-viewing-angle display
Dual display for displaying two properties of an input signal (e.g., ac voltage in one
display and frequency in the other).
Remote operation via IEEE 488, RS-232, and Ethernet interface.
Trigger in and measurement-complete out
Front panel USB port for optional memory
6-1/2 digit resolution
Half-rack width
True rms ac
2 and 4-wire resistance measurements
Extended 10
Frequency measurements to 1 MHz
Capacitance measurements (4050 Only)
Temperature measurement (4050 Only)
10 A current capability
Decibels (dB and dBm) with variable reference impedance and audio power
measurement capability
Input terminals on both front and rear panels of the meter
Closed-case calibration (no internal calibration adjustments)
and 1 G ranges
