upper and lower limits. The following commands may be used
to set the fan speed tolerance limits.
SENSE:FREQ1:RANGE:UPPER 6500
SENSE:FREQ1:RANGE:LOWER 2000
Each of these commands has an associated query.
example, the query:
SENSE:FREQ1:RANGE:LOWER?
reads the lower fan speed tolerance limit. Refer to Table 5-2
for a description of a range of values accepted for this
command.
The The ambient temperature is monitored to ensure that it does
not exceed an upper limit. The following command may be
used to set the ambient temperature limit.
SENSE:TEMP14:RANGE:UPPER
This example sets the upper limit of the ambient temperature to
63 degrees Celsius. The present upper limit for the ambient
temperature may be read with the query:
SENSE:TEMP14:RANGE:UPPER?
Refer to Table 5-2 for a description of a range of values
accepted for this command.
Each VXI slot is individually monitored to ensure that the
temperature rise above ambient does not exceed its
programmable limit. Each VXI slot temperature rise may be
programmed individually. The following commands may be
used to establish the slot's upper limit for temperature rise
above the measured ambient temperature.
