I/V Sweep Measurement
Figure 7-5 Synchronous Sweep Measurement
Pulsed Sweep Measurement
For a sweep measurement, a sweep or constant source SMU can be a pulse source.
But only one SMU can be a pulse source.
Figure 7-6 shows the relationship between pulse source and other sources. Each step
of the primary sweep source is synchronized with ou
tput of the SMU pulse source.
Measurements are made during the pulse output. For the pulsed sweep
measurement, the delay time setting is ignored.
The following setup is required to perform the pulsed sw
eep measurements. See
“I/V Sweep” on page 5-4 for the GUI.
1. Select the following on the Channel Setup tab screen.
• Select VAR1 for the Function of the SMU used for VAR1.
• Select V, VPULSE, or COMMON for the Mode of current monit
or SMU, or
I or IPULSE for voltage monitor SMU. Pulse is available only for one SMU.
2. Set the VAR1 channel as shown in “Basic Sweep Measurement”.
3. Specify the following parameters for the SMU Pulse on the Measur
ement Setup
tab screen.
