Qualifier)
Arguments for
Command or
Response to Query
Description of Arguments
(Note that all arguments are ASCII numeric codes, i.e., ASCII codes between 48 and 57)
Query
(Instr Code and
Qualifier)
Response to Query
(Target to controller)
Auto Fault
Recovery AFR= 1 byte,
value of 0, 1
Command or Query.
The SSPA output will automatically be muted in the event of detected fault. If auto fault
recovery is enabled, it will cause the output to go active (un-mute) if all faults are cleared. If
disabled, the output will remain muted even if all faults are cleared.
AFR? AFR=x
(same format as
command arguments)
RF Power
Amplifier State
AMP= 1 byte,
value of 0, 1
Command or Query.
Turns ON or OFF the RF power amplifiers.
0 = Off
1 = On
Example: AMP=1
AMP? AMP=x
(same format as
command arguments)
Attenuation ATT= 5 bytes,
numerical
Command or Query.
Valid attenuation level, in dB, at 0.25-dB step size as factory default.
Example: ATT=12.25 ATT? ATT=xx.xx
(same format as
command arguments)
Clear All Stored
Events CAE= None Command only.
Instructs the KPA to clear all Stored Events
This command takes no arguments.
Example: <1/CAE=’cr’
N/A
N/A
Concise
Alarm Status
N/A variable length, alpha
numerical
Query only.
Used to Query the Alarm status of the unit.
Example: <0001/CAS?
>0001/CAS=a;b;c;d;e;f;g;h;i;j;k;l;m;n;o;’cr’’lf’ where:
0 = OK, 1 = Fault, 3 = Not Applicable, 4 = Alarm, 5 = Masked
a = 28V Power Supply
b = 15V Power Supply
c = 7.5V Power Supply
d = 5V Power Supply
e = -5V Power Supply
f = 9V or 10V RF Power Supply 1
g = 9V or 10V RF Power Supply 2
h = Heat-Sink Temperature 1
i = Heat-Sink Temperature 2
j = Isolator Load Temperature
k = Shutdown
l = Fan 1
m = Fan 2
n = BUC
o = External Reference
CAS? CAS=x….x
