Configures the device to wait for the complex power of the I/Q data to cross the specified threshold to mark a reference point within the record. On a MIMO session, configures the IQ Power edge trigger on the master port. By default, the selected port configured to segment0/chain0 is considered as master port.
To trigger on bursty signals, specify a minimum quiet time, which ensures that the trigger does not occur in the middle of the burst signal. The quiet time must be set to a value smaller than the time between bursts, but large enough to ignore power changes within a burst.

Syntax

Namespace: NationalInstruments.RFmx.WlanMX

public int ConfigureIQPowerEdgeTrigger(string selectorString, string iqPowerEdgeTriggerSource, RFmxWlanMXIQPowerEdgeTriggerSlope iqPowerEdgeTriggerSlope, double iqPowerEdgeTriggerLevel, double triggerDelay, RFmxWlanMXTriggerMinimumQuietTimeMode triggerMinimumQuietTimeMode, double triggerMinimumQuietTimeDuration, RFmxWlanMXIQPowerEdgeTriggerLevelType iqPowerEdgeTriggerLevelType, bool enableTrigger)

Parameters

NameTypeDescription
selectorStringstring

Pass an empty string. The signal name that is passed when creating the signal configuration is used.

iqPowerEdgeTriggerSourcestring

Specifies the channel from which the device monitors the trigger.This parameter is used only when you set the Trigger Type method to IQ Power Edge. The default value of this method is hardware dependent. To make a specific MIMO port as the trigger master, use the port specifier format port::(device_name)/(source_terminal). Example: “port.myrfsa1/0”

iqPowerEdgeTriggerSlopeRFmxWlanMXIQPowerEdgeTriggerSlope

Specifies whether the device asserts the trigger when the signal power is rising or when it is falling. The device asserts the trigger when the signal power exceeds the specified level with the slope you specify.

iqPowerEdgeTriggerLeveldouble

Specifies the power level at which the device triggers, depending on the value of the iqPowerEdgeTriggerSlope parameter. The value is expressed in dB when the iqPowerEdgeTriggerLevelType parameter is set to Relative , or in dBm when it is set to Absolute .

triggerDelaydouble

Specifies the trigger delay time. This value is expressed in seconds.

triggerMinimumQuietTimeModeRFmxWlanMXTriggerMinimumQuietTimeMode

Specifies whether the measurement computes the minimum quiet time used for triggering.

triggerMinimumQuietTimeDurationdouble

Specifies the duration for which the signal must be quiet before the signal analyzer arms the I/Q power edge trigger. This value is expressed in seconds. If you set SetIQPowerEdgeTriggerSlope(string, RFmxWlanMXIQPowerEdgeTriggerSlope) to Rising , the signal is quiet when it is below the trigger level.

iqPowerEdgeTriggerLevelTypeRFmxWlanMXIQPowerEdgeTriggerLevelType

Specifies whether the IQPowerEdgeLevel is set to Relative or Absolute . The value is expressed in dB when this parameter is set to Relative . The value is expressed in dBm when this parameter is set to Absolute .

enableTriggerbool

Specifies whether the trigger is used.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
