Block Converter (BUC / BDC) Remote Commands and Queries

Command Arguments for
Parameter (Instruction Command or
Type Code and Response to
Qualifier)
Attenuation AOF= 5 bytes
Offset
Attenuation ATT= 5 bytes,
Calibrate LNA CLC= none
Current
(BDC only)
(Note that all arguments are ASCII numeric codes between 48 and 57)
Query
Command or Query.
Note: Command is only for the offline converter in a redundancy mode. The valid range is -3.00 to
+3.00 dB.
Additionally, if the online converter attenuation is set to one extreme or the other, that value
becomes the new limiting factor. For example, if the attenuation is set to 19dB, the only
allowable offset will be -3 dB to +1 dB.
Default Value: 00.00
Example: <2/AOF=+2.25'cr'
>0002/AOF='cr''lf'
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.
Stores t he v alue of t he LN A C urrent S upply (i n m A) as a ref erence p oint. The LN A c urrent
alarm/fault point is then based on this point  the LCW setting.
Note: This command will return a mode error if the LCS output has not been enabled first. It will
return 000.0 if the converter has never been calibrated.
Example: <1/CLC='cr'
>0001/CLC='cr''lf'
The CLC query will return the value that was stored during the LNA current calibration.
Example: <1/CLC?'cr'
>0001/CLC=xxx.x
(where xxx.x is calibrated LNA current value in mA)
