Appendix C
C.6.1 Remote Commands and Queries (FW Version 2.X.X and Higher)
Command Arguments for
Parameter Type (Instr Code and Command or
Qualifier) Response to Query
Auto Fault AFR= 1 byte,
Recovery value of 0, 1
RF Power AMP= 1 byte,
Amplifier State value of 0, 1
Attenuation ATT= 5 bytes,
numerical
Clear All Stored CAE= None
Events
Concise N/A variable length, alpha
Alarm Status numerical
Description of Arguments
(Note that all arguments are ASCII numeric codes, i.e., ASCII codes between 48 and 57)
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.
Command or Query.
Turns ON or OFF the RF power amplifiers.
0 = Off
1 = On
Example: AMP=1
Command or Query.
Valid attenuation level, in dB, at 0.25-dB step size as factory default.
Example: ATT=12.25
Command only.
Instructs the KPA to clear all Stored Events
This command takes no arguments.
Example: <1/CAE='cr'
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
