CHP:Noise Calibration:Mode Property
Short Name: CHP Noise Cal Mode
Property of RFmxSpecAn
Specifies whether the noise calibration and measurement is performed manually by the user or automatically by RFmx. Refer to the measurement guidelines section in the Noise Compensation Algorithm topic for more information.
You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.
The default value is Auto.
| Manual (0) |
When you set the CHP Meas Mode property to Calibrate Noise Floor, you can initiate instrument noise calibration for the CHP measurement manually. When you set the CHP Meas Mode property to Measure, you can initiate the CHP measurement manually. |
| Auto (1) |
When you set the CHP Noise Comp Enabled property to True, RFmx sets Input Isolation Enabled to Enabled and calibrates the intrument noise in the current state of the instrument. RFmx then resets the Input Isolation Enabled property and performs the CHP measurement, including compensation for noise of the instrument. RFmx skips noise calibration in this mode if valid noise calibration data is already cached. When you set the CHP Noise Comp Enabled property to False, RFmx does not calibrate instrument noise and performs only the CHP measurement without compensating for the noise contribution of the instrument. |
