The pulsev and pulsei commands generate either a positive or negative voltage, as specified by
the sign of the value argument. With both the pulseV and pulseI commands:
• A positive value generates a positive voltage from the high terminal of the source.
• A negative value generates a negative voltage from the high terminal of the source.
After the pulseX command is executed, other commands may be used to make measurements. The
meas
X command can measure:
• Residual voltage or current as it decays after removal of the initial application.
• Capacitance between DUT pins as the residual voltage or current decays.
All measurements made using the pulseX and measX commands are processed after the pulse has
completed.
Whenever the pulseX command is run, either a default or a programmed current or voltage limit is in
ef
fect. The type of limit depends on the type of pulseX command:
• The pulsev command has an automatic current limit default. For example, a SMU used as a
v
oltage source defaults to a current limit of 10 mA. You can call the limiti command before th
e
pulseV
command to override the default.
• The pulsei command has an automatic voltage limit default. For example, a SMU used as a
c
urrent source defaults to a voltage limit of 20 V. You can call the limitv command before t
he
pulsei
command to override the default.
When using the limitX and pulseX commands on the same source at the same time in a test
sequence, call the limitX command first, then call the pulseX command.
