proposes a reflection normalization on port 2 (see "Start Cal Unit... (P2) Refl OSM /
Start Cal... (P2) Refl OSM" on page 322)
●
enables the Fault Limit Check and Fault Limit controls
●
displays an additional "Distance Domain" trace info line below the channel line
Note that all info lines (channel info, trace info,"Distance Domain" trace info) allow
quick access to related parameters via specific context menus:
Remote command:
CALCulate<Chn>:TRANsform:DTFault:STATe
Start Distance / Stop Distance
Define the distance window for the Distance to Fault measurement. "Start Distance"
and "Stop Distance" correspond to the left and right edge of the diagram area and are
displayed in the "Distance Domain" trace info line.
Note:
●
If the "Stop Distance" is so high that for the selected cable type the signal reflected
at "far away discontinuities" would be too small, a warning tooltip is displayed:
●
If the "Stop Distance" exceeds the unambiguous range (for the given frequency
span and number of sweep points), a warning is displayed in the instrument status
bar:
Use the Auto Number of Points function to adjust the number of sweep points so
that the impulse response becomes unambiguous in the configured distance win-
dow.
Remote command:
CALCulate<Chn>:TRANsform:DTFault:STARt
CALCulate<Chn>:TRANsform:DTFault:STOP
CALCulate<Chn>:TRANsform:DTFault:CENTer
CALCulate<Chn>:TRANsform:DTFault:SPAN
Auto Number of Points
Selects the minimum number of sweep points that are required to provide an unambig-
uous display of fault locations for the active Distance to Fault trace.
If "Auto Number of Points" actually modifies the Number of Points, a tooltip is dis-
played:
