Frequency / Transm. Coefficients: Insert, Delete, Delete All
The required two-port information is a list of transmission coefficients at different fre-
quency values (power loss list). The buttons in the dialog provide different ways of cre-
ating and modifying the list. Use "Insert", "Delete", "Delete All" to edit the list manually.
In a power, time or CW mode sweep, one point at the fixed CW frequency is sufficient.
In a frequency sweep, it is possible to enter several coefficients to account for a fre-
quency-dependent attenuation. Transmission coefficients are interpolated between the
frequency points and extrapolated, if necessary.
If no transmission coefficient is defined at all, the R&S ZNA assumes a 0 dB attenua-
tion across the entire frequency range. This assumption is equivalent to an ideal
through connection or selecting "No Coefficients" in the Power Meter Transmission
Coefficients dialog.

Get Trace...
Opens a selection box containing all traces in the active recall set. The "dB Mag" val-
ues of the selected trace are used to define the transmission coefficients. Notice that if
you combine different channels with different sweep points, the analyzer possibly has
to interpolate or extrapolate the transmission coefficients.
Remote command:
SOURce:POWer:CORRection:TCOefficient:FEED
Import File...
Imports the transmission coefficients from a trace file. The imported file must be either
in Touchstone (*.s<n>p) or in *.csv format; see also Chapter 4.4.2, "Trace files",
on page 176.
Remote command:
MMEMory:LOAD:CORRection:TCOefficient<Ch>
Recall... / Save...
You can save the displayed power loss list to a power meter correction list file with
extension (*.pmcl) and reload it in later sessions.
Remote command:
MMEMory:LOAD:CORRection:TCOefficient<Ch>
MMEMory:STORe:CORRection:TCOefficient<Ch>
