4 Up to 100different sequences can be linked to run steps ofvarious operating modes and loading sequence can also be programmed withupper and lower limit Pass/Fail criteria. Whenapplied in production testing, you can easilyjudge whether the test parameters of yourdevices are within the specification limits andadjust your process according to the modeNot limited to just switching between two levels,list mode lets you generate more complexsequences of input changes with several differentlevels. Up to 7 groups of list files can be savedand executed in CC mode via internal or externaltrigger. Each list can contain up to 84 steps withvarying slew rates and a minimum width time of20 s per modeUse the load s unique CR-LED operating modeto test LED drivers. This function allows users toconfigure the LED s operating resistance and forward voltage to simulate the loading behaviorof typical voltage operationThe 8600 Series can operate at low voltages for applications such as fuel cell and solar cell = Forward voltage of the LEDRd = LED operating resistanceVo = LED operating voltageIo = LED operating VLED I-V CurveVoltage01234586028600860115304560 Typical minimum operating voltage at full scale current:Transient operation enables the load to periodicallyswitch between two load levels (A/B).

9 (2)The slew rate specifications are not warranted, but are descriptions of typical performance. The actualtransition time is defined as the time for the input to change from 10% to 90%, or vice versa, of the programmed current values. In case of very large load changes, from no load to full load , the actualtransition time will be larger than the expected time. The load will automatically adjust the slew rate to fitwithin the range (high or low) that is closest to the programmed value.
