Digital Multimeters — Tektronix DMM4020
SignalExpress acquiring data from Tektronix DMM4020 and DPO3052.
Connect Your Bench for Intelligent Debug
Easily capture, save, and analyze measurement results from your
multimeter with the special Tektronix Edition of National Instrument’s
LabVIEW S ignalExpress™ software. Every DMM4020 multimeter ships
with a free copy of the Limited Edition version of SignalExpress for basic
instrument cont rol, data logging, and analysis. The optional Professional
Edition offers over 20 0 built-in functions that provide additional signal
processing, advanced analysis, sweeping, limit testing, and user-defined
step capabilities.
SignalExpress support s the range of Tektronix bench instruments*

,
enabling you to connect your entire test bench. You can then access the
SignalEx
press used to export DMM4020 data into Excel.
feature-rich tools packed into each instrument from one intuitive software
interface. This allows you to automate complex measurements requiring
multiple instruments, log data for an extended period of time, time correlate
data from multiple instruments, and easily capture and analyze your results,
all from
your PC. Only Tektronix offers a connected test be nch of intelligent
instruments to simplify and speed debug of your complex design.
Performance You Can Count On
In addition to industry-leading service and support, every DMM4020
multimeter comes backed with a three-year standard warranty.
