Auto Fault
Recovery
AFR=
AFR?
1 byte
Command or Query.
Sets or returns automatic fault recovery in the form x, where:
0=Disabled
1=Enabled
(DEFAULT)
NOTES
:
1)
If auto fault recovery is enabled, it causes the output to return to its pre-fault mute condition if all faults are
cleared. If disabled, the output remains muted even if all faults are cleared. The LPOD output automatically
mutes if one of the following fault conditions occur:
•
BUC lock detect fault
•
LNB current fault
•
LNB voltage fault
2)
These faults can be user defined as faults, alarms, or masked (see MSK command for more info).
COMMAND EXAMPLE:
<0001/AFR=1{CR}
AFR=
AFR?
AFR*
AFR=x
RF Power
Amplifier State
AMP=
AMP?
1 byte
Command or Query.
Sets or returns the RF power amplifiers status in the form x, where:
0=Off
(DEFAULT)
1=On
NOTE:
Turning the amplifier off disables the +10V supply, and masks it during fault checking.
COMMAND EXAMPLE:
<0001/AMP=1{CR}
AMP=
AMP?
AMP*
AMP=x
Attenuation
Offset
AOF=
AOF?
5 bytes
Command or Query.
Sets or returns the attenuation offset level in the form xx.xx, where:
xx.xx=00.00
(DEFAULT)
to 20.00, in dB, in 0.25 dB steps
NOTE:
This value is not copied to the offline unit in a redundancy system, but is added to the attenuation value upon
a switchover. This provides a unit-specific fine-tune to maintain power levels appropriately in a redundancy system.
COMMAND EXAMPLE:
<0001/AOF=12.25{CR}
AOF=
AOF?
AOF*
AOF=xx.xx
Attenuation
ATT=
ATT?
5 bytes
Command or Query.
Sets or returns the attenuation level in the form xx.xx, where:
xx.xx=00.00 to 20.00, in dB, in 0.25 dB steps
Default value:
10.00
COMMAND EXAMPLE:
<0001/ATT=12.25{CR}
