TERMination represents a receiver noise measurement in
channel <Ch>, with a matched load connected to receiving port
<TestPort>. This is part of a noise figure calibration using
mechanical calibration standards (with option R&S ZNA-K30).
MDELay represents a delay mixer calibration that is required for
calibrating a two-tone group delay measurement (with option
R&S ZNA-K9).
<TestPort> Test port number.
For a transmission standard, an adapter that is used as a
"through", or a mixer, the input and output port numbers must be
specified.
For reflection standards, only one port number is required.
*RST: n/a
<SecondPortOrAdapter>For a transmission standard, an adapter that is used as a
"through", or a mixer, this parameter specifies the second test
port.
For reflection measurements with an adapter connected
between port and standard, set it to ON.
Otherwise set it to OFF or simply omit it.
<Dispersion> Optional status parameter for UTHRough standard:
OFF - unknown through standard is non-dispersive.
ON - unknown through standard is dispersive.
*RST: OFF
<DelayTimePhase> Optional entry of delay time or phase for UTHRough standard:
AUTO - the analyzer determines the delay time or phase during
the calibration sweep.
<delay or phase> - entry of the delay time in ps (for non-disper-
sive standards) or of the phase at the start frequency of the
sweep in deg (for dispersive standards). If an estimate of the
start phase is entered, the analyzer uses the calculated value
which is closest to the estimate.
Automatic determination of the phase
The UOSM algorithm provides the transmission factor of the
unknown through standard up to an ambiguous sign. This yields
the two alternative phase values displayed in the calibration wiz-
ard; see Unknown Through Standard.
