alarm limits:
Seven VXI power supply outputs and +5VSTDBY. In Volts.
Default alarm limits: Per VXI regulation spec for each voltage, fixed.
Seven VXI power supply outputs. In Amps.
Default alarm limits: Specified peak current for each output voltage,
user-settable via SCPI command.
Note that measurement accuracy may cause an alarm even if peak current
has not exceeded specified maximum. Limit may need to be adjusted higher.
Seven VXI power supply outputs. In Watts.
Accuracy: Value calculated from voltage and current measurements.
Default alarm limits:Specified peak power level for total power,
user-settable via SCPI command. Note that measurement accuracy may
cause an alarm even if power has not exceeded specified maximum. Limit
may need to be adjusted higher.
Module cooling fan (impeller). Power supply cooling fan(s). In % of speed
and rpm.
