M9506A-BC1 5-Slot AXIe Chassis with Integrated Controller User Guide 53
SCPI Programming Interface 4
SCPI Functions
This section describes the SCPI command interface for the integrated controller
and digitizers reports error conditions via the ‘
:SYST:ERR?
’ query. The buffer for
‘
:SYST:ERR?
’ is a LIFO buffer and will store up to 10 error messages before
flushing the last message in the buffer to make room for the next. When becoming
familiar with the digitizers and integrated controller, it is recommended to
routinely read this buffer as there is one common buffer for reporting all error
returns.
Digitizer Commands
:DIGitizer[N]:STATus?
Query
:DIGitizer[N]:STATus?
Description This query returns “IDLE”, “WAITING_TRIGGER”, or “MEASURING”, as string.
-
IDLE – Digitizer is waiting for command.
Note that if the digitizer has not been calibrated, the digitizer will stay in “IDLE”
state until self-calibration has been completed. When a digitizer has been
triggered, it will be returned to “IDLE” status as well when acquisition is
complete.
- WAITING_TRIGGER – Digitizer is armed and awaiting trigger. A digitizer is placed
in this mode when either the :ARM command or the :DIG[n]:ARM command is
executed, and will stay armed until a trigger event occurs, an unarm command
is executed, or a reset to the digitizer occurs.
- MEASURING – Digitizer trigger event has occurred, and digitizer is completing
measurement/acquisition. This status for general data acquisition happens so
quick that it is not observed. This is more applicable when DDC or a custom
FPGA function is implemented requiring significant processing on the digitizer.
At the time when this manual was written, these features have not been
enabled when using the integrated controller.
Example
-> dig3:stat?
<- "IDLE"
