The 4200 load is designed for use within the main-

frame power module chassis included as part of the
NHR S400 and 5600 power supply test systems. This
load provides advanced control and measurement
capabilities by incorporating the task-essential fea-
tures of a DMM, DSO and ARB. With this built-in
capability, the 4200 load delivers a single integrated-
test-solution that provides more comprehensive test
information. The load also eliminates the additional
cost, reliability and test-speed penalties when multiple
single-purpose instruments are necessary to supple-
ment a less capable load.

WAVEFORM CAPTURE, ANALYSIS AND DISPLAY

The 4200 load digitizes device-under-test output volt-
age and current waveforms for both analysis and dis-
play. The advantage of each load having this capabili-
ty is that any number and type of output waveform-to-
waveform measurements such as timing can now be
made within a single test step. Further, all the wave-
forms and digital control signals can be combined
together on a single screen. With this additional layer
of visual information the designer or test engineer has
a higher level of product performance information
than would be available from just a strict numeric
record of test results.
