– When TDR Sweep is set to Auto, this is the maximum stop
frequency of the measurement. The minimum value of this setting is 100 MHz.
TDR Start and Stop Distance
In TDR measurements, you set the physical length of the DUT. The FieldFox
calculates the frequency range of the measurement from this distance. The
longer the DUT, the lower the frequencies that are used.
You can NOT set the frequencies manually in TDR. However, you CAN limit the
maximum frequency using the TDR Sweep setting. Learn more in
