upper and lower limits. The following commands may be used
to set the fan speed tolerance limits.
SENSE:FREQ1:RANGE:UPPER 6500
-- fan, upper limit
SENSE:FREQ1:RANGE:LOWER 2000
-- fan, lower limit
Each of these commands has an associated query. For
example, the query:
SENSE:FREQ1:RANGE:LOWER?
reads the lower fan speed tolerance limit. Refer to
Table

Tolerance Limit
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 63.0
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.
Programming The VXI
Slot Temperature Rise
Tolerance Limits
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.
SENSE:TEMP1:RANGE:UPPER 11.0
-- Slot C0 temp rise
SENSE:TEMP2:RANGE:UPPER 12.0
-- Slot C1 temp rise
SENSE:TEMP3:RANGE:UPPER 13.0
-- Slot C2 temp rise
SENSE:TEMP4:RANGE:UPPER 15.0
-- Slot C3 temp rise
SENSE:TEMP5:RANGE:UPPER 9.0
-- Slot C4 temp rise
SENSE:TEMP6:RANGE:UPPER 11.0
-- Slot C5 temp rise
SENSE:TEMP7:RANGE:UPPER 22.0
-- Slot B0 temp rise
