Function Details
I/V Sweep Measurement
I/V Sweep Measurement
For the I/V sweep measurements, sweep source channels (SMU) perform staircase
sweep output of voltage or current, while monitor channels (SMU) measure voltage
or current for each sweep step. According to the output function, the following
measurements are available. See Figure 7-1 for the SMU output function.
• “Basic Sweep Measurement” by using VAR1 function
• “Subordinate Sweep Measurement” by using VAR1 and VAR1’ functions
• “Synchronous Sweep Measurement” by using VAR1 and VAR2 functions,
VAR1’ function is also available
• “Pulsed Sweep Measurement”
This is the basic, subordinate, or synchronous sweep measurement using a pulse
output SM
U. Only one pulse output SMU is available.
Figure 7-1 SMU Output Function and Sweep Output
Available Modules
SMUs and SPGUs can be used. SMU can be constant voltage/current source or
pulse voltage/current source and perform voltage/current measurement. SPGU can
be pulse voltage source. See “SPGU Module” on page 7-26 for using the SPGU.
If multiple measurement channels are used, the channels perform measurement in
order. See “Mu
ltiple Measurement Channels” on page 7-61.
