TEST PRINTOUT

The 4200 load is designed for use within the mainframe 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 features of a DMM, DSO and ARB. With this built-in capability, the 4200 load delivers a single integratedtest-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 supplement a less capable load.

WAVEFORM CAPTURE, ANALYSIS AND DISPLAY

The 4200 load digitizes device-under-test output voltage and current waveforms for both analysis and display. The advantage of each load having this capability is that any number and type of output waveform-towaveform measurements such as timing can now be made within a single test step. Further, all the waveforms 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.

AUTO MODE

The 4200 contains a unique Auto Mode that provides glitchless automatic switching between CR, CC, CV and CP limits. Previously challenging tests that are now made possible include turn-on into a CR load, confirming the complete V-I curve for lithium-Ion battery chargers, and preventing deviceunder-test blowup should a protection circuit fail.

POWERFUL TRANSIENT GENERATOR

A greatly expanded range of single burst or continuous waveforms are now possible through the built-in waveform/transient generator. Almost any waveform can be created with up to100 programmable steps. Waveforms can be programmed in the CV, CP and CR modes as well as the customary CC mode.

COMPATIBLE WITH THE HIGHLY FLEXIBLE POWER MODULE SUBSYSTEM

Within the mainframe power module chassis, the Model 4200 may be combined with Model 4100/4110 loads as well as 6000/6100 Series DC sources. The 4200 is also software parallelable, which allows real time reconfiguration of larger, virtual loads. In this manner, the load creates another dimension of power module flexibility that assures adapting to new numbers of outputs and power level needs in the future.
