FACTORY commands
Only the query formats of these commands are accessible by the customer.
•
FACTory:SNINst
Command to query the modulator’s serial number.
Example:
FACT:SNIN?
Response:
1234567
•
FACTory:SNXAcboard
Command to query the serial number of the XA control board.
Example:
FACT:SNXA?
Response:
1234567
•
FACTory:MONitor:LIMits
Command to query various lower and upper factory limits, namely limits for the master
controller’s board temperature (MC_BT), the 2.5 V (MC_025V), 3.3 V (MC_033V), 5.0 V
(MC_050V) and the 12V (MC_120V) supply voltages and the chip voltages VCCP1 (MC_VP1)
and VCCP2 (MC_VP2).
Example:
FACT:MON:LIM? “MC_BT”
Response:
50,55
Note the alarm limits for the temperature sensor are “level” limits, i.e. a warning is given on
reaching the first alarm level, in the form of an alarm pending message. On reaching the
second, upper, limit, the modulator displays a “FATAL ERROR message. Note remote control is
still possible in this situation.
The other alarm limits are “out of window” limits. A warning, in the form of a pending alarm, will
be given when the actual level goes out of the window range limit.
•
FACTory:MONitor:CURRent?
Command to query the current value of the various factory monitored parameters, namely the
master controller’s board temperature (MC_BT), the 2.5 V (MC_025V), 3.3 V (MC_033V), 5.0 V
(MC_050V) and the 12V (MC_120V) supply voltages and the chip voltages VCCP1 (MC_VP1)
and VCCP2 (MC_VP2).
Example:
FACT:MON:CURR? “MC_BT”
Response: 52
