Returns the peak power of the center channel. This value is expressed in dBm. Details

Spectral Measurements:EDRInBandEmission:Results:Upper Channel Power (dBm)

Returns the peak power of the upper channel adjacent to the center frequency. This value is expressed in dBm. Details

Returns the peak power of the lower channel adjacent to the center frequency. This value is expressed in dBm. Details

Spectral Measurements:EDRInBandEmission:Results:Measurement Start Channel

Returns the start channel used for the EDRInBandEmission measurement. The toolkit computes the start channel based on the device under test (DUT) transmit channel number and the EDRInBandEmission Number of Channels property.

If you set the EDRInBandEmission Offset Channel Position property to InBand, the toolkit measures the number of channels around the DUT transmit channel number, and limits the channel power measurements within Bluetooth band for EDR packets. Valid values for measurement start channel are 0 to 78, inclusive.

If you set the EDRInBandEmission Offset Channel Position property to Centered, the toolkit calculates the measurement start channel using the following formula: (value returned by the EDRInBandEmission Number of Channels property - 1) / 2. Details

Spectral Measurements:EDRInBandEmission:Results:Channel Powers[] (dBm)

Returns the array of power values of all channels as specified in the Test Specification Radio Frequency Test Suite Structure (TSS) and Test Purposes (TP) Specification 1.2/2.0/2.0+EDR/2.1/2.1+EDR/3.0/3.0+HS. The size of the array is the same as the value returned by the EDRInBandEmission Number of Channels property. The first element in the array corresponds to the measurement start channel. This value is expressed in dBm. Details

Spectral Measurements:EDRInBandEmission:Results:Guard Position (sec)

Returns the guard offset. This value is expressed in seconds. Details

Specifies the number of 1 MHz channels used for LEInBandEmission measurements. The toolkit increments this property by 1 in the following conditions:

The default value is 40. Valid values are 1 to 80, inclusive. For the NI PXIe-5663, valid values are 1 to 45, inclusive. Details

Spectral Measurements:LEInBandEmission:Measurement Method

Specifies the measurement method for LEInBandEmission measurements. Details

Spectral Measurements:LEInBandEmission:Auto Sweep Time Enabled

Specifies whether to enable auto sweep time for LEInBandEmission measurements. Details

Specifies the sweep time for LEInBandEmission measurements. This value is expressed in seconds.

The default value is 10 ms. Details

Spectral Measurements:LEInBandEmission:FFT Window Type

Specifies the time-domain window type that is used for spectral smoothing. Configure this property only if you set the LEInBandEmission Measurement Method property to FFT.

The default value is Flat Top. Details

Spectral Measurements:LEInBandEmission:Number of Averages

Specifies the number of acquisitions over which the toolkit averages LEInBandEmission measurements using peak-hold averaging.

The default value is 1. Details

Spectral Measurements:LEInBandEmission:Detector Type

Specifies the method that the toolkit uses to detect the power within each detection interval when you set the LEInBandEmission Measurement Method property to Sweep, and it detects the power across overlapping FFTs when you set the LEInBandEmission Measurement Method property to FFT. Details

Spectral Measurements:LEInBandEmission:Offset Channel Position

Specifies the position of the offset channel that is measured. Details

Spectral Measurements:LEInBandEmission:Results:Measurement Status

Indicates the status for the LEInBandEmission measurement based on the measurement limits specified in section 5.1.15 of Bluetooth Test Specification v4.0. Details

Spectral Measurements:LEInBandEmission:Results:Reference Channel Power (dBm)

Returns the peak power of the center channel. This value is expressed in dBm. Details

Spectral Measurements:LEInBandEmission:Results:Upper Channel Power (dBm)

Returns the peak power of the upper channel, 2 MHz away from the center frequency. This value is expressed in dBm. Details

Spectral Measurements:LEInBandEmission:Results:Lower Channel Power (dBm)

Returns the peak power of the lower channel, 2 MHz away from the center frequency. This value is expressed in dBm. Details

Spectral Measurements:LEInBandEmission:Results:Measurement Start Channel

Returns the start channel used for the LEInBandEmission measurement. The toolkit computes the start channel based on the device under test (DUT) transmit channel number and the LEInBandEmission Number of Channels property. Details

Spectral Measurements:LEInBandEmission:Results:Channel Powers[] (dBm)

Returns the array of total power values of all channels. The size of the array is the value returned by the LEInBandEmission Number of Channels property. The first element in the array corresponds to the measurement start channel. This value is expressed in dBm.

The toolkit averages this measurement, using peak-hold averaging, over the number of acquisitions specified by the LEInBandEmission Number of Averages property. Details

Advanced:Auto Packet Detection Enabled

Specifies whether the toolkit automatically detects the packet type or uses the packet type that you specify in the Packet Type property. Details

Advanced:Acquisition Time

Specifies the acquisition time. This value is expressed in seconds. This property is applicable only when you set the Auto Packet Detection Enabled property to True. For larger number of measurement averages, this property should be set to a higher value depending on the duration of the packet. Details
