The electrical delay function compensates for the electrical delay of the trace measurement. This function is useful during measurements of phase deviations from linear, for example.
If the electrical delay setting is other than zero, the S-parameter value will be corrected in accordance with the following formula:
,
where — frequency, Hz,
— electrical delay, sec.
The electrical delay can be specified in seconds or as an equivalent length (meters, feet, inches). When the equivalent length is used, it is also possible to select media (coax or waveguide) and to set the velocity factor and WG Cutoff (for waveguide only).
The electrical delay is set for each trace independently. The trace to which the function is applied must be preselected as active (See Selection of Active Trace/Channel ).
