TDR
This function shows the pair as a “trace” on the screen. TDR measures distance to events based on input about the pair.
TDR Setup
TDR features a setup function that allows you to enter the cable type, gauge and first length. Vp is then automatically set from these selections. Press the [Setup] key to change the Cable Type, Gauge, or to select either minimum first length or last used.
There are six modes to view a pair: 1) Single Trace to view a single pair. 2) Dual Trace to view two pairs at the same time. 3) Differential to view the difference between two pairs. 4) Crosstalk to view the electrical coupling between two pairs. 5) Memory to compare a “live” trace with a trace stored in memory. 6) Peak to display a history of maximum and minimum values with the live trace.
Press the [Up] or [Down] keys to move to a desired selection. Press the [Enter] key to accept the choice and start the measurement.
