Amplifier Communication and Protocol, Rabbit CPU
Sub-Band Select
Command Byte:
‘PBS’
Function:
Allows the user to change the sub-band of the HPA to support
multiple BUC sub-bands or to support optimized Linearizer tuning within
each sub-band.
Parameters:
‘1’ - Sets HPA to sub-band 1.
‘2’ - Sets HPA to sub-band 2.
Compatibility:
HPAs with either band-switchable BUCs or Linearizer with
sub-band optimization.
Reset Processor
Command Byte: ‘
’
Function:
Resets the processor.
Note:
Unit does not reply to this command.
Set Attenuator
Command Byte:
‘K’
Parameter:
“XX.X” dB of attenuation OR
“IX.X” to increase attenuation by X.X OR
“DX.X” to decrease attenuation by X.X
Function:
Instantly sets the attenuator to the specified dB level. Use caution,
as sudden large changes to output power can damage the TWT.
Response:
Resulting attenuation in XX.X dB. If the user specified an
attenuation value outside the attenuator’s range, the closest valid value will
be used.
Note:
Use this to find max attenuation. For example, send {AK 99.9}. A
typical response would be {AK 30.0}, indicating a 30 dB attenuation range.
Compatibility:
Attenuator required.
