TDR Mode (Time Toolbar)

Use the Time measurement toolbars to perform the measurements listed in this topic's menu. For TDR/TDT measurements, standards may specify the thresholds used to determine the risetime of a discontinuity that is measured on a TDR/TDT waveform. You can specify this threshold ( 10%/90% or 20%/80%) in the Thresholds tab of the Configure Measurements dialog box. These measurements use the same algorithm as the corresponding Oscilloscope measurements.
