Delay settings
Enter delay in either Distance or Time by entering a value or clicking the up/down arrows. Click
the Step Size dialog.
Time The amount of port extension delay in time. Enter a positive value.
Distance The amount of port extension delay in physical length. Enter a positive value.
Distance Units (Dialog ONLY) Select from Meters, Inches, or Feet. The Step Size setting will not change
automatically. Learn more.
Loss Compensation
The following settings allow the entire frequency span to be corrected for loss.
Loss at DC Offsets the entire frequency span by this value. Loss1 or Use1 must also be checked. To
compensate for loss at DC, enter a positive value which causes the trace to shift in the positive (up) direction.
Loss @Frequency Check the box, and enter values for Loss and Frequency
When Loss1 or Loss1/Loss2 are used, a curved-fit algorithm is used as follows:
Loss1 ONLY:
Loss(f) = Loss1 * (f/Freq1) ^ 0.5
Loss1 and Loss2:
Set the lower frequency to Loss1, and the higher frequency to Loss2.
Loss(f) = Loss1 * (f/Freq1) ^ n
Where:
n = log10 [abs(Loss1/Loss2)] / log10 (Freq1/Freq2)
Note: abs = absolute value
Velocity
Velocity Factor For each port, sets the velocity factor that applies to the medium of the device that was
inserted after the measurement calibration. The value for a polyethylene dielectric cable is 0.66 and 0.7 for
PTFE dielectric. 1.0 corresponds to the speed of light in a vacuum.
Couple to system Velocity Factor When unchecked, the Velocity Factor is set for only the specified port
and only for Port Extensions. When checked, sets the Velocity Factor for all ports. In addition, changing this
value also changes this setting for the
Media
For each port, select the media of the added transmission line or fixturing.
Coax Select when the fixture or added transmission line is coax. Also specify the velocity factor of the coax.
Waveguide / Cutoff Frequency Select when the fixture or added transmission line is waveguide. Also enter
cutoff (minimum) frequency of the waveguide.
Note: when using a Waveguide cal Kit, set
Couple to system Media Definition. When unchecked, the Waveguide Cutoff Frequency is set for only the
specified port and only for Port Extensions. When checked, sets the Waveguide Cutoff Frequency for all
