5 SCPI Command Reference
:PLUGin:OTIMing:RUN:LOG?
Syntax :PLUGin:OTIMing:RUN:LOG? ‘identifier’
Input
Parameters
‘identifier’: Specify the measurement name.
Description This command returns logs for the addressed measurement.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example This command returns logs for the measurement ‘MyMeasurement’.
:PLUG:OTIM:RUN:LOG? ‘MyMeasurement’
The format of log returned is in the following way:
#XY Message Log
where X denotes the length of digits for Y, Y denotes the number of
characters in the log then followed by the log message.
For example:
#10 means, there is 1 digit after 1 and there is 0 character in the log.
#2492 means, there are 3 digits after 2 and there are 492 characters in the
log message.
:PLUGin:OTIMing:RUN:MESSage?
Syntax :PLUGin:OTIMing:RUN:MESSage? ‘identifier’
Input
Parameters
‘identifier’: Specify the measurement name.
Description This command returns a string describing the state of an output timing
measurement addressed by the measurement name identifier. Possible
states include NotStarted, Running, Suspended, Finished, Error, or
Stopped.
This SCPI is applicable for M8041A, M8051A, M8062A and M8046A.
Example The following example returns the state of an output timing measurement
with the measurement name identifier called ‘MyMeasurement’:
:PLUG:OTIM:RUN:MESS? ‘MyMeasurement’
Running
