Setting up Analyzer 6
The M8046A Error Detector provides 120 pre-defined equalization levels
for NRZ signals and 55 equalization levels for PAM4 signals. These
equalization levels can be adjusted on the data input to compensate for
the loss characteristic of the back channel. Specifications on these
equalization levels can also be found in M8040A data sheet.
After changing the equalization level, it is required to re-adjust the
threshold voltages again, or use the auto-alignment to re-optimize the
sample point setting.
