Specify how the timing resolution is to be reported:
meas:fem2:par:tres:type UINT
5
Specify how the threshold is to be reported:
meas:fem2:par:thr:type ABS
6
Check the timing resolution and threshold at points 1 and 6:
meas:fem2:par:point? 1
-4.0E-1,1.525000035763E-1
meas:fem2:par:point? 6
1.6E-1,-4.749999642372E-2

Running the Eye Diagram
Running the Eye Diagram - Concepts
The Eye Diagram measurement is generally used for production and screening
tests. It helps in determining very quickly whether the eye opening seen at the
output signal of a device is within specifications, that is, within certain timing and
voltage limits.
The following topics inform you on how you can run the Eye Diagram
measurements.
To be able to set up and run an Eye Diagram measurement using SCPI, you should
know that this measurement is implemented as an object on the instrument. You
must first create an instance of the object, and then use the returned handle to
address this object.
As a good programming practice, remember to close the object when you are
finished with your test.
