Sweep Measurement Mode
Synchronous Sweep Measurement
For synchronous sweep measurement, you set up a synchronous sweep source
(VAR1') in addition to a primary sweep source (VAR1). The output of the
synchronous sweep source is swept synchronously with the output of the primary
sweep source at a constant offset value and ratio.
Figure 2-3 Synchronous Sweep Measurement
To set up synchronous sweep measurement, select the following on CHANNELS:
CHANNEL DEFINITION page:
• VAR1 function for desired primary sweep source (SMU or VSU).
• VAR1' function for desired synchronous sweep source (SMU or VSU).
Synchronous sweep mode has the following restrictions:
• For the following, VAR1' is always set to the same mode as VAR1:
• linear/log staircase
• single/double sweep mode
• VAR1 and VAR1' must be same V/I output mode. For example, if VAR1 is set to
V mode, then VAR1' must be set to V or VPULSE mode.
