Running the Eye Diagram - Procedures
The following code indicates how you could set up and run the Eye Mask using
SCPI.
N O T E
The Eye Diagram measurement displayed in the user interface cannot be controlled
remotely. When you set up a program to run an Eye Diagram measurement remotely,
a separate measurement object is created. The user interface does not reflect any
change in program for this measurement object.
Example to Running the Measurement
To run the measurement:
1
Create the session:
:meas:emas(*):cre?
2
The return value 2 is the handle.
2
Start the measurement: meas:gen2:go
3
To get the measured data: :meas:emas2:fetc:data? 102017
Running JTol Characterization
Running JTol Characterization - Concepts
The Jitter Tolerance Characterization test determines the amplitude of jitter a data
receiving circuit can cope with before it produces an untolerable number of errors.
The following topics inform you on how you can programmatically set up Jitter
Tolerance Characterization measurements.
See the online Help or the User's Guide for details on working with the Jitter
Tolerance Characterization.
To be able to set up and run a Jitter Tolerance Characterization measurement using
SCPI, you should be aware that the measurement is programmatically implemented
as an object on the instrument. You must first create an instance of the object, and
then use the handle returned to address this object.
As good programming practice, also be sure to close the object when you are
finished with your test.
