Description

RFMXVNA_VAL_SPARAMS_FORMAT_MAGNITUDE

0 (0x0)

Sets the format of the selected S-Parameter to Magnitude. You can specify RFMXVNA_ATTR_SPARAMS_MAGNITUDE_UNITS.

RFMXVNA_VAL_SPARAMS_FORMAT_PHASE

1 (0x1)

Sets the format of the selected S-Parameter to Phase. Phase values are expressed in degrees. Phase can be represented in various, mathematically equivalent ways such as phase wrapped between the range [-180, 180) degrees, or phase can be represented in an unwrapped manner. You can specify the phase representation by configuring RFMXVNA_ATTR_SPARAMS_PHASE_TRACE_TYPE.

RFMXVNA_VAL_SPARAMS_FORMAT_COMPLEX

2 (0x2)

Sets the format of the selected S-Parameter as complex numbers in cartesian co-ordinates.

RFMXVNA_VAL_SPARAMS_FORMAT_SWR

3 (0x3)

Sets the format of the selected S-Parameter to Standing Wave Ratio (SWR). SWR is a unitless quantity.

RFMXVNA_VAL_SPARAMS_FORMAT_SMITH_IMPEDANCE

4 (0x4)

Sets the format of the selected S-Parameter to Smith Impedance. S-Parameter values are transformed into impedence values. Impedence values are expressed in ohms. You can use these values to plot on a Smith Chart.

RFMXVNA_VAL_SPARAMS_FORMAT_SMITH_ADMITTANCE

5 (0x5)

Sets the format of the selected S-Parameter to Smith Admittance. S-Parameter values are transformed into admittance values. Admittance values are expressed in siemens. You can use these values to plot on an Inverted Smith Chart.

RFMXVNA_VAL_SPARAMS_FORMAT_POLAR

6 (0x6)

Sets the format of the selected S-Parameter as complex numbers in polar co-ordinates, where the radial axis (i.e., magnitude of the complex numbers) is always in linear scale and angular axis (phase) is represented in degrees and always wrapped between ±180 deg.
