Measuring VXI Slot
Temperature
Each VXI slot temperature may be read individually. The
following commands may be used to read the specified VXI slot
temperature:
MEAS:TEMP1?
-- read slot 0 temperature
MEAS:TEMP2?
-- read slot 1 temperature
MEAS:TEMP3?
-- read slot 2 temperature
MEAS:TEMP4?
-- read slot 3 temperature
MEAS:TEMP5?
-- read slot 4 temperature
MEAS:TEMP6?
-- read slot 5 temperature
MEAS:TEMP7?
-- read slot 6 temperature
MEAS:TEMP8?
-- read slot 7 temperature
MEAS:TEMP9?
-- read slot 8 temperature
MEAS:TEMP10?
-- read slot 9 temperature
MEAS:TEMP11?
-- read slot 10 temperature
MEAS:TEMP12?
-- read slot 11 temperature
MEAS:TEMP13?
-- read slot 12 temperature
Each of these queries causes the 1261B EMS to reply with a
value formatted as a real number. The number is rounded to the
nearest 0.1 degree Celsius.
Note that the temperature rise of any slot may be computed by
the difference between the ambient temperature and the slot’s
temperature ((MEAS:TEMPX?) - (MEAS:TEMP14?)).
Measuring Fan
Speed
Each of the three fan speeds may be read individually. The
following commands may be used to read the fan speed:
MEAS:FREQ1?
-- read SLOWEST fan speed
MEAS:FREQ2?
-- read Fan #1 fan speed
MEAS:FREQ3?
-- read Fan #2 fan speed
MEAS:FREQ4?
-- read Fan #3 fan speed
Each of these queries causes the 1261B EMS to reply with an
integer value. The fan speed is rounded to the nearest whole
number. The unit of measure is RPM (revolutions per minute).
