Prepare the Measurement
To create the measurement object and prepare the measurement:
1
Create the session:
meas:jtol:char:cre?
7
Note that the returned number (handle) has to be used as a suffix in each of
the subsequent SCPI commands to address the measurement.
2
Specify the target bit error ratio:
meas:jtol:char7:par:btes:tber 1.0E-12
3
Specify how the target BER shall be verified:
meas:jtol:char7:par:btes CLEV
4
For confidence mode (CLEVel), set the confidence level:
meas:jtol:char7:par:btes:clev 95E-2
5
Specify the frequencies to be measured. The following command creates a list
of 10 logarithmically equidistant steps between 10 kHz and 10 MHz:
meas:jtol:char7:par:flis:fill 1.0E+4, 1.0E+7, 10
6
Decide on the search method. The following establishes a downwards
logarithmic search:
meas:jtol:char7:par:sear DLOG
7
Set the stop value. This is the minimum jitter amplitude in UI:
meas:jtol:char7:par:sear:dlog:stop 1.0E-1
8
Set the ratio between two vertical amplitude steps:
meas:jtol:char7:par:sear:dlog:rati 6.6E-1
Run the Measurement
To run the measurement:
1
Start the measurement:
meas:gen7:go
2
Check if the measurement has finished:
meas:gen7:opc? BLOC
1
Or check the measurement progress:
meas:gen7:prog?
