Set B_level
The sink current toggles between a high value and a low value in
continuous mode. The B_Level indicates a high value. The default unit for
B_Level is Ampere (A).
Set width
A_width/B_width: The time during which the sink current stays at Level A.
Default units are s or ms and the available range is 0.020 ms - 999 s.
Slew_RIS and Slew_FAL
Slew_RIS and Slew_FAL: The set rate of change to a new level from the
current value. Units are A/us and the available range is 0.001 - 2.5 A/us.
3. Enable trigger
Press Shift + CP key to enter the Utility interface. After pressing the “Config”
key, the trigger source can be set in page 2 of the selection menu which
includes Manual/Ext/Bus. Manual displays a trigger softkey on page 3 of the
Dynamic test. Pressing this key will trigger the step. Ext sets the trigger type
to external, which looks for a valid trigger on the rear panel Ext Trig input.
Bus
is
a
trigger
sent
over
the
remote
control bus. See “Set
trigger” in Section 3 for more details. Press On/Off to turn on the channel
input. At this time, the actual input voltage, current, resistance and power
will be displayed on the main interface. The sink current will toggle continuously
between the set A level and B levels.
Tip:
The sink current may maintain a constant value in the main interface
when the width is set to a very small value because the load is
switching too quickly between A_level and B_level set points. Use the
waveform display function to see the waveform more clearly.
4. View waveform display
Press Display to enter waveform display interface, shown in figure
2-18. The waveform will display the current curve when ”I” is selected in CC
Cont mode. Press Display again to exit the waveform display interface and
return to the main interface of CC Cont mode.
