xTalk TDR
Current Group displays the test being measured.
Current Test allows you to select either Auto, Manual, or xTalk TDR.
Note: The test has the same parameters as the Manual TDR test and does not
inherit Auto TDR settings (Range, Gain, Pulse Width) when switching to
the test from the Current Test setup line.
Range allows you to set the range from the given list.
Gain allows you select the gain test parameter from the given list.
Pulse Width allows you to select a value from a given list.
Dual Trace Offset % is a configurable offset parameter for the
secondary trace, with a range of -100 % to +100 %.
Note: If the loaded secondary trace offset = 0, then the primary and secondary
traces will overlap.
VOP allows you to change the velocity of propagation value for the
cable as defined in m/μsec (meters per microsecond), a ratio, or
percentage of the speed of light.
Current Trace allows you to turn on/off Live and Peak traces by
selecting one of the following:
Live turns Peak Hold OFF clearing previously collected
minimum/maximum measurement values. This is the default.
Live and Peak turns Peak Hold ON and collects
minimum/maximum measurement values, displaying all 3 traces.
Peak Only turns Peak Hold ON displaying only Peak traces with no
offset.
Cable Setup button opens a new page that allows you to set the Cable
Parameters for the Current Test.
