Boost Your Measurement Speed & Efficiency
The GDM-8261A is a high precision 6 V2 digit Digital Multimeter with dual measurement displays, ii measurement functions and i0 math
functions at high accuracy (35ppm DC voltage accuracy) to accommodate the most frequently performed parameter measurements in
various application fields today.
The GDM-8261A adopts a scanner card, which carries 16 V-Channels and 2 I-Channels, to facilitate the measurements of multiple-test
points on either a device or multiple devices all at a press ofa button. \X/ith this multi-point measurement capability, the GDM-8261A can
be used as a semi-auto ATE System to increase the throughput of manufacturing test or as a data logger to perform long term monitoring
or characterization ofa DUT. A PC Software, DMM-Viewer, is available with GDM-8261A to support multi-channel panel setting and data
logging ofthe scanner card. Besides, a LabVlE\X/ driver is also supported to help user create his/her own virtual instrument on the PC
screen for easy programming. For ATE system measurements or remote control applications, both USB and RS-232C Interfaces are
provided as standard, and either GPIB or LAN can be selected as optional interface for the GDM-8261A.
The GDM-8261A includes all the basic measurement functions that
are required for engineers to handle design, development and
' testing jobs for electronic circuits or products. The basic

accommodate specific measurement requirements and complex
measurement applications.

Unlike most ofthe “dual disp|ay” digital multimeters, which show
test result on the primary display and range information on the
secondary display, the GDM-8261A is able to perform two
measurement functions simultaneously and shows the test results
on primary display and secondary display respectively. tasks.
The GDM-8261A supports an almost unlimited number of
measurement combinations ofdual measurement functions,
besides the normal test result and range information displays,
greatly increases the test speed of multi-function measurement

measurement. This level of resolution and accuracy becomes a must
for the precision measurements in specific applications. In addition,
the GDM-8261A is capable of acquiring 30 measurement readings/s
at the display resolution of4 V2 digits and 2,400 readings/s at the
display resolution of6 Z digits. The fast acquisition rate ofthe
GDM-8261A adequately meets today's measurement demands.
