If this is selected, RJ/DJ separation is not available.
•
BER Threshold
To calculate the parameters for the given BER threshold. This is the
BER level for which output timing numerical values (phase margin,
skew, etc.) are calculated. It is also the upper limit of the BER range
for RJ/DJ separation.
The BER threshold influences some of the parameters of the DUT
Output Timing measurement. You can also drag and drop the
horizontal BER threshold in the graphical display to change this
value.
•
Min BER for RJ/DJ Separation
Lower limit of the BER range for RJ/DJ separation.
•
Residual BER for Estimated Total Jitter
BER level for which the estimated total jitter is calculated. See
“Estimated Total Jitter” on page 177
for details on how it is used.
You can select the number of
Decimal Places
to be displayed in the table.
Graph Tab
On the
Graph
tab, you can use the several options to optimize the
graphical display according to your needs.
Choose between
Unit Interval
and
Seconds
to select the timebase for the
display's x-axis.
Choose between
Logarithmic
and
Linear
to select the scale for the display's
y-axis.
For example, a DUT Output Timing measurement displayed on a linear
scale may look like this:
