5.8.2 Configuration Commands
5.8.2.1 Amplifier ON/OFF
The XPA200-7984-I provides the user direct control of the 10
VDC supply voltage to the solid state RF power FETs. This
feature provides the ability to put the SSPA into a low power
consumption mode when the unit is offline. The default is on.
Amplifier control: <DEV/AMP _ xxx'cr' xxx = ON or OFF
Confirmation: >DEV/AMP _ xxx'cr''lf']
Retrieve AMP Status: <DEV/AMP _ 'cr'
Confirmation: >DEV/AMP_xxx'cr''lf']
5.8.2.2 Mute Output
The user is provided output mute control via the remote
interface using this command. The default is on.
Mute Output: <DEV/MUT _ xxx'cr' xxx = ON or OFF
Confirmation: >DEV/MUT _ xxx'cr''lf']
Retrieve Mute Status: <DEV/MUT _ 'cr'
Confirmation: >DEV/MUT_xxx'cr''lf']
5.8.2.3 Attenuator
The default is 10 dB.
Set Attenuator: <DEV/ATT_ yy.yy'cr'
Confirmation: >DEV/ATT _ yy.yy'cr'lf']
Retrieve Attenuator:: <DEV/ATT _ 'cr'
Confirmation: >DEV/ATT_ yy.yy'cr''lf']
Note: yy.yy = 0.0 to 20.00 dB in 0.25 steps.
5.8.2.4 Auto Fault Recovery
The SSPA output is automatically muted in the event of a
detected fault. Auto Fault Recovery, if enabled, will cause the
output signal to go active (unmuted) if all faults clear. If
disabled, the output will remain muted even after all faults
clear until a MUT_OFF command is received (see 5.8.2.2). The
default is off.
