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
Sweep type
Sweep direction
Hold time
Delay time
• 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.
8-20
Maximum 1001 for one VAR1 sweep.
Linear or logarithmic
Single or double sweep
Initial wait time or wait time after VAR2 is set, 0 to 655.35 s
with 10 ms resolution
Wait time from VAR1 step to the start of the measurement, 0
to 65.535 s with 100 μs resolution
