How to Adjust the Sampling Point Manually
For manual adjustments, select the vertical voltage axis and move the
sampling point vertically towards other location at the selected delay. The
same can also be done by changing the Threshold value in the Parameter
window. The Sample Point on the sampling diagram moves vertically as
you change the value.
In case of PAM4 line coding in M8046A analyzer, there are three vertical
voltage axis which represents Upper, Middle and Lower threshold value.
You can move the sampling point vertically towards the other location at
the selected delay.
The same can also be done by changing the Upper, Middle and Lower
threshold value in the Parameter window.
Similarly, select the horizontal axis and move the sampling point
horizontally towards the other location at the selected voltage. The same
can also be done by changing the Delay value in the Parameter window.
The Sample Point in the sampling diagram moves horizontally as you
change the value.
