Sweep Measurement Mode
For sweep measurements, the sweep source channels perform staircase sweep
output of voltage or current, while the monitor channels measure voltage or current
for each sweep step.
Only SMUs and VSUs can be sweep sources (VAR1, VAR2, and VAR1').
The 4155B/4156B provides three types of sweep measurement:
•“Basic Sweep Measurement”
One sweep source (VAR1) is used.
•“Subordinate Sweep Measurement”
A primary (VAR1) and secondary sweep source (VAR2) are used.
•“Synchronous Sweep Measurement”
A primary (VAR1) and synchronous sweep source (VAR1') are used.
Also, you can set up a combined subordinate and synchronous sweep measurement.
In addition to the normal dc sweep, the sweep or constant source output can be
pulsed to prevent thermal drift of the DUT.
