Power Supply
Alarm Mask
MPS= 2 bytes Command or Query
Sets or returns Power Supply Alarm mask conditions in the form ab, where:
0 = Fault, 1 = Alarm, 2 = Masked
a = Power Supply 1
b = Power Supply 2
Default value: 12
If MPS=00 and any of the voltages on either supply are out of range, then both front panel
“SUM FAULT” LEDs are lit, the summary fault relay is put in the "faulted" position, it is a logged
event, and no switchover occurs.
If MPS=11 and any of the voltages on either supply are out of range, then both front panel “SUM
FAULT” LEDs are lit, the summary fault relay is not affected, it is a logged event, and no
switchover occurs.
If MPS=22 and any of the voltages on either supply are out of range, then both front panel “SUM
FAULT” LEDs are NOT lit (because of the power supply), the summary fault relay is NOT
affected, it is NOT a logged event, and no switchover occurs.
If BOTH power supplies are faulted, then a fault is reported even if they are masked.

Unit Alarm Mask MSK= 5 bytes Command or Query.
Alarm mask conditions. If an alarm is masked, neither an alarm or a fault is set, and the user will not
know of a problem, in the form abcde, where:
0 = Fault, 1 = Alarm, 2 = Masked
a = Low Forward RF Power
b = External Reference Lock detect
c = Converter A Not Inserted
d = Converter B Not Inserted
e = LNA Current Detect
Default value: 22111
Note: There could be a variable delay in the time it takes for the internal reference to lock to an
external reference, due to warm-up characteristics and frequency differences between the
references. Therefore, the default setting is "masked" for the reference lock detect. This setting
may be changed if the customer so desires. The delay should be less than 1 second after 30
minutes of warm-up time.

Unit returns the Number of stored Eventsthat remain Unread in the form xxx.
