RF Power
Amplifier State AMP= PCB 1 byte,
value of 0, 1
Command or Query.
Turns ON or OFF the SSPAs in the form AMP=x, where:
0 = Off
1 = On AMP=
AMP?
AMP* AMP? ALL AMP=x
(see Description
of Arguments for
details)
Attenuation
Offset AOF= PCB 7 bytes,
alphanumeric
Command or Query.;
Sets attenuation offset for specified SSPA
Command: AOF=x,yy.yy where:
x=0 or 1 (SSPA number)
yy.yy=Attenuation offset
Query: AOF?
Example: AOF=1,01.50
Note: AOF command will not take values greater than 6 dB)
AOF=
AOF?
AOF* AOF? PCB AOF=x,yy.yy
(see Description
of Arguments for
details)
Attenuation ATT= PCB 5 bytes,
numerical
Command or Query.
Valid attenuation level, in dB, at 0.25-dB step size as factory
default.
Example: ATT=12.25
Note: The attenuation range is limited to a maximum of 24 dB. ATT=
ATT?
ATT* ATT? ALL ATT=xx.xx
(see Description
of Arguments for
details)
AUX Input
Enable AUX= N/A 1 byte,
value of 0, 1
Query only.
Enables AUX input for SSPA mute
<0001V1/AUX?
Where: x is 0 (AUX Mute disabled)
1 (AUX Mute enabled) AUX=
AUX?
AUX* AUX? SSPA AUX=x
(see Description
of Arguments for
details)
Bypass SSPA BYP= PCB 1 byte
value of 0, 1 or
2
Command or Query.
Command: BYP=a, where:
a = 0 (No SSPA is bypassed)
1 (SSPA #1 is bypassed)
2 (SSPA #2 is bypassed)
• Command bypasses the SSPA specified by argument.
• Command works only in RED=0 mode.
Query: BYP?
• Query returns the number of the SSPA that is currently
bypassed or offline.
• Query works in any RED mode.
BYP=
