smua.pulser.protect.sensev
This attribute sets a voltage protection level used to monitor the sense terminals when the pulser is enabled.

Usage
level = smua.pulser.protect.sensev
smua.pulser.protect.sensev = level
The voltage protection level when the pulser is enabled; the value must be between
5% and 200% of the voltage range set by the smua.pulser.rangeY attribute
Details
If the voltage on the sense terminals goes above the protection level, the 2601B-PULSE output is
shorted for the remainder of the sweep and the output turns off at the end of the sweep.
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.sensev = 8
Set the voltage protection limit to 8 V.
