Sweep Measurements

Measurement Functions

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.

The 4155C/4156C 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.

Available Units SMUs and VSUs can be sweep sources (VAR1, VAR2, and VAR1'). A sweep or

constant source SMU can be set to the pulsed source to prevent thermal drift of the

DUT.

Output Range Sweep source units use the following output range:

• minimum range covers all sweep output values in Linear sweep.

• minimum range covers all sweep output values in Log voltage sweep.

• optimum range for output value every sweep step in Log current sweep.
