Protection Mask (Enable Alarms)
The protection mask allows for the different alarms to be masked, completely disabling them. This means that the SCPI status and operations registers will not detect the alarms. You will have no way of knowing the current operation state of the alarm. The protection mask is a feature that is only accessible using the SCPI command noted below.
Command:
[:]SYSTem[<channel>]:PROTection[:MASK] {?<mask>}
