Flexible operation
List mode lets you generate more complex
sequences of input changes with several different
levels. Up to 7 groups of list files can be saved.
Each list can contain up to 84 steps with a
minimum width time of 20 µs per step.

Vd = Forward voltage of the LED
Rd = LED's operating resistance
Vo = Operating voltage across the LED
Io = Operating current across the LED
Use the load's unique CR-LED operating mode
to test LED drivers. This function allows users to
configure the LED's operating resistance and for-
ward voltage along with the voltage range (same
as CR operation) to simulate the loading behavior
of typical LEDs.

Automatic test mode
The 8600 Series can execute multiple test
sequences in automatic test mode. Up to 100
different sequences can be linked to run steps of
various operating modes and loading conditions.
Each sequence can also be programmed with
upper and lower limit Pass/Fall criteria. When
applied in production testing, you can easily
judge whether the test parameters of your devices
are within the specification limits and adjust your
process according to the Pass/Fail verdict.
Transient operation
Transient operation enables the module to peri-
odically switch between two load levels. A power
supply's regulation and transient characteristic
can be evaluated by monitoring the supply's out-
put voltage under varying combinations of load
levels, frequency, duty cycle, and slew rate. Tran-
sient operation can simulate these conditions.
Low voltage operation
The 8600 Series can operate at low voltages for applications such as fuel cell and solar cell testing.
