Measurement Capability
The 4155C/4156C can perform dc or pulsed force/measure, and stress force. For dc,
voltage/current sweep and sampling (time domain) measurements are available.
Voltage/Current Sweep Measurement Characteristics
SMUs or VSUs can be set using VAR1 (primary sweep), VAR2 (subordinate
sweep), VAR1' (synchronous sweep), or CONST (constant output).
• VAR1
Primary sweep, controls the staircase (dc or pulsed) voltage or current sweep.
Number of steps Maximum 1001 for one VAR1 sweep.
Sweep type Linear or logarithmic
Sweep direction Single or double sweep
Hold time Initial wait time or wait time after VAR2 is set, 0 to 655.35 s
with 10 ms resolution
Delay time Wait time from VAR1 step to the start of the measurement, 0
to 65.535 s with 100
μ
s resolution
• VAR2
Subordinate linear staircase or linear pulsed sweep. After primary sweep is
completed, the VAR2 unit output is incremented. Maximum number of steps is
128.
