RFmx
The RFmxDemodMX type exposes the following members.
Methods
| Name | Description | |||
|---|---|---|---|---|
 | AbortMeasurements | Stops acquisition as well as the measurements that are associated with the signal instance and that were previously initiated by the Initiate(String, String) method or measurement Read methods. | ||
| AnalyzeIQ1Waveform |
Performs the enabled measurements on the I/Q complex waveform that you specify in iq parameter. Call this method after you configure the signal and measurement properties. You can fetch measurement results using the Fetch methods. Use this method only if the RFmxInstrMX.SetRecommendedAcquisitionType method
is IQ. This method is supported only when the RFmxInstr session is created with option string "AnalysisOnly=1".
| ||
| AutoLevel | Examines the incoming signal to calculate the peak power level and sets the power level based on the value of the reference level. Use this method to help calculate an approximate setting for the power level for measurements. | ||
 | BuildResultString | Creates the selector string for use with Configuration or Fetch methods. | ||
| CheckMeasurementStatus | Checks the measurement status for demodulated measurements. | ||
| ClearAllNamedResults | Clears all results for the current signal instance. | ||
| ClearNamedResult | Clears a result instance specified by the result name in the selectorString parameter. | ||
| CloneSignalConfiguration | Creates a new instance of a signal by copying all the values from an existing signal instance. | ||
| Commit | Commits settings to the hardware. Calling this method is optional. RFmxDemod commits settings to the hardware when you call the RFmxInstr Initiate method or any of the measurement Read methods. | ||
| ConfigureDigitalEdgeTrigger | Configures the digital-edge trigger. | ||
| ConfigureExternalAttenuation | Configures the attenuation of a switch (or cable) connected to the RF IN connector of the signal analyzer. | ||
| ConfigureFrequency | Configures the expected carrier frequency of the RF signal that needs to be acquired. The signal analyzer tunes to this frequency. | ||
| ConfigureIQPowerEdgeTrigger | Configures the I/Q power-edge trigger. | ||
| ConfigureReferenceLevel | Configures the reference level that represents the maximum expected power of an RF input signal. This value is expressed in dBm for RF devices and Vpk-pk for baseband devices. | ||
| ConfigureRF | Configures the RF properties of the signal by specifying the selector string. | ||
| ConfigureSoftwareEdgeTrigger | Configures the software-edge trigger. | ||
| DeleteSignalConfiguration | Deletes the current instance of the signal. | ||
| DisableTrigger | Disables the trigger. | ||
| Dispose | Deletes the signal configuration if it is not the default configuration and clears any trace of the current signal configuration, if any. | ||
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object) | ||
| GetAllNamedResultNames | Returns all the named result names of the current signal instance. | ||

| GetAttributeDouble | Gets the value of a double attribute. | ||
| GetAttributeInt | Gets the value of an integer attribute. | ||
| GetAttributeSByteArray | Gets the value of a signed byte array attribute. | ||
| GetAttributeString | Gets the value of a string attribute. | ||
| GetAutoLevelInitialReferenceLevel | Gets the reference level which represents the maximum expected power of the RF input signal. This value is expressed in dBm for RF devices and Vpk-pk for baseband devices. | ||
| GetCenterFrequency | Gets the carrier frequency, in hertz (Hz), of the RF signal to acquire. The signal analyzer tunes to this frequency. | ||
| GetDigitalEdgeTriggerEdge | Gets a value that indicates whether the signal analyzer detects a rising or falling edge on the digital-edge trigger signal. | ||
| GetDigitalEdgeTriggerSource | Gets the value that indicates the source terminal for the digital-edge trigger. | ||
| GetErrorString | Gets the error description that specifies the origin/reason of the error or warning. | ||
| GetExternalAttenuation | Gets the attenuation, in dB, of a switch (or cable) connected to the RF IN connector of the signal analyzer. | ||
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object) | ||
| GetIQPowerEdgeTriggerLevel | Gets the power level at which the device triggers. This value is expressed in dB when you set the GetIQPowerEdgeTriggerLevelType(String, RFmxDemodMXIQPowerEdgeTriggerLevelType) to Relative and in dBm when you set the GetIQPowerEdgeTriggerLevelType(String, RFmxDemodMXIQPowerEdgeTriggerLevelType) method to Absolute. The device asserts the trigger when the signal exceeds the level specified by the value of this method, taking into consideration the specified slope. This method is used only when you set the GetTriggerType(String, RFmxDemodMXTriggerType) method to IQ Power Edge. | ||
| GetIQPowerEdgeTriggerLevelType | Gets the reference for the SetIQPowerEdgeTriggerLevel(String, Double) method. This method is used only when you set the SetTriggerType(String, RFmxDemodMXTriggerType) method to IQPowerEdge. | ||
| GetIQPowerEdgeTriggerSlope | Gets the value that indicates whether the device asserts the trigger when the signal power is rising or falling. | ||
| GetIQPowerEdgeTriggerSource | Gets the channel from which the device monitors the trigger. | ||
| GetLimitedConfigurationChange | Gets the set of properties that are considered by RFmx in the locked signal configuration state. | ||
| GetReferenceLevel | Gets the reference level which represents the maximum expected power of the RF input signal. This value is expressed in dBm for RF devices and Vpk-pk for baseband devices. | ||
| GetReferenceLevelHeadroom |
Gets the margin RFmx adds to the Reference Level method. The margin avoids clipping and overflow warnings if the input signal exceeds the configured reference level. RFmx configures the input gain to avoid clipping and associated overflow warnings provided the instantaneous power of the input signal remains within the reference level plus the reference level headroom. If you know the input power of the signal precisely or previously included the margin in the reference level, you could improve the signal-to-noise ratio by reducing the reference level headroom.
