smua.pulser.protect.sourcev
This attribute sets an absolute voltage protection level used to monitor the force terminals when the pulser
is enabled.

Usage
level = smua.pulser.protect.sourcev
smua.pulser.protect.sourcev = level
The absolute voltage protection level when the pulser is enabled; 2 V to 40 V
Details
If the voltage on the force terminals goes above the protection level, the 2601B-PULSE automatically
turns off the output.
The absolute voltage protection level ignores normal transients during the pulse rise and fall time.
The current pulse terminates within 3 µs after the remotely sensed voltage from the device under test
(DUT) exceeds the specified level.
Setting the protection level does not guarantee that the output will not go above the
protection level. The 2601B-PULSE turns off the output as quickly as possible, but the voltage
level can briefly exceed this level, potentially causing damage to the device under test (DUT).
The settings for this attribute are ignored if the pulser is disabled.
Example
smua.pulser.protect.sourcev = 8
Set the voltage protection limit to 8 V.
