Description of Arguments
(Note that all arguments are ASCII numeric codes
to Query
Command or Query.
Valid attenuation level (00.00 to 50.00 for x-band BUC units, 00.00
to 20.00 for all other), in dB, in 0.25 dB steps as factory default.
Default Value: 00.00
Example: <2/ATT=12.25'cr'
>0002/ATT='cr''lf'
Note: Attenuation cannot be changed for the offline unit when in
redundancy mode.
Command or Query.
Valid Operating RF frequency, in MHz.
For Ku BDCs only:
FRE values: 10950-11700 MHz an LO of 10000 MHz is activated
FRE values: 11700-12250 MHz an LO of 10750 MHz is activated
FRE values: 12250-12750 MHz an LO of 11300 MHz is activated
Example: FRE=11300.000'cr'
Note: Operating Frequency cannot be changed for the offline unit
when in redundancy mode.
Command or Query.
Used to set up and query the global status of the BUC/BDC.
Example: GCC=aa.aa;b;ccccc.cc; 'cr' where:
aa.aa = attenuation in dB (ATT)
b = mute state, 0 = un-muted, 1 = muted (MUT)
ccccc.ccc = frequency in MHz (FRE, Ku BDC only, other units will
display xxxxx.xxx)
Note: This command can only be queried for the offline unit when
in redundancy mode.
Command or Query.
Mute the unit, where:
0 = Disabled (Not Muted)
1 = Enabled (Muted)
Default Value: 0
Example: <2/MUT=1'cr'
>0002/MUT=1'cr''lf'
Note: Mute State cannot be changed for the offline unit when in
redundancy mode.
