Owning Palette: Configuration

Use the VIs on this palette to configure spectral emission mask (SEM) measurements. You can also use the RFmxSpecAn Property Node to configure additional properties.

Palette Object Description
RFmxSpecAn SEM Configure Number of Carriers

Configures the number of carriers for the spectral emission mask (SEM) measurement.

RFmxSpecAn SEM Configure Carrier Enabled

Configures whether to consider the carrier power as part of total carrier power measurement.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Carrier Offset

Configures the center frequency, in Hz, of the carrier, relative to the RF center frequency.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Carrier Integration Bandwidth

Configures the frequency range, in Hz, over which the measurement integrates the carrier power.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Carrier RBW Filter

Configures the resolution bandwidth (RBW) filter of the carrier signal.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Carrier RRC Filter

Configures the root raised cosine (RRC) channel filter to apply on the acquired carrier channel before measuring the channel power. RRC alpha is the filter roll off.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Carrier Channel Bandwidth

Configures the channel bandwidth of the carrier.

Use "carrier<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Number of Offsets

Configures the number of offset segments for the spectral emission mask (SEM) measurement.

RFmxSpecAn SEM Configure Offset Frequency

Configures the offset frequency start and stop values and specifies whether the offset segment is present on one side, or on both sides of the carriers.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset RBW Filter

Configures the resolution bandwidth (RBW) filter of the offset segment.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Bandwidth Integral

Configures the resolution of the spectrum to compare with spectral mask limits as an integer multiple of the resolution bandwidth (RBW).

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Relative Attenuation

Configures the attenuation, in dB, relative to the external attenuation.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Limit Fail Mask

Specifies the criteria to determine the measurement fail status.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Absolute Limit

Configures the absolute limit mode and specifies the absolute power limits corresponding to the beginning and end of the offset segment.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Relative Limit

Configures the relative limit mode and specifies the relative power limits corresponding to the beginning and end of the offset segment.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Offset Frequency Definition

Configures the offset frequency definition for the SEM measurement.

Use "offset<n>" as the selector string to configure this VI.

RFmxSpecAn SEM Configure Power Units

Configures the units for the absolute power.

RFmxSpecAn SEM Configure Reference Type

Configures whether the power reference is the integrated power or the peak power in the closest carrier channel.

RFmxSpecAn SEM Configure Sweep Time

Configures the sweep time.

RFmxSpecAn SEM Configure Averaging

Configures averaging for the spectral emission mask (SEM) measurement.

RFmxSpecAn SEM Configure FFT

Configures window and FFT to obtain a spectrum for the spectral emission mask (SEM) measurement.

RFmxSpecAn Build Carrier String2

Creates the carrier string to use as the selector string with the SEM, ACP, and CHP carrier configuration or fetch properties and VIs.

RFmxSpecAn Build Offset String2

Creates the offset string to use as the selector string with SEM and ACP offset configuration or fetch properties and VIs.
