Power Reference Tab (Spectral Emissions Mask)

Power Reference Tab

Power Reference - Sets the overall type of power reference.

Left and Right Carriers - Reference is the left and right edge of carriers in the subblock.

Maximum Power - Reference is the carrier with the highest power.

Index - Reference is power in the carrier specified by Power Reference Carrier Index.

Manual - Reference power is manually entered by Total Power Ref, PSD Reference or Peak Power Reference depending on Reference Power Selection.

Max Power Carrier in Subblock - Reference is the carrier with the highest power in subblock.

Default: Maximum Power

Choices: Left and Right Carriers, Maximum Power, Index, Manual, Max Power Carrier in Subblock

Reference Power Selection - Sets the overall type of power calculation used. The selection specifies the format of the power reference and related results.

Integrated Power - Reference is total integrated power of the reference carrier(s), and measured results are in units of dBc deciBels referenced to the carrier: A technique for expressing a power measurement in logarithmic form using the carrier power as a reference. and dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer.

PSD Power Spectral Density: See power spectral density. - Reference is the mean power spectral density of the reference carrier(s), and measured results are in units of dB and dBm/Hz.

Spectrum Peak - Reference is the peak bin power in the spectrum of the reference carrier(s), and measured results are in units of dB and dBm.

Default: Spectrum Peak

Choices: Integrated Power, PSD, Spectrum Peak

Power Reference Carrier Index - Sets the index of the carrier used for the power reference.

Default: 0

Total Power Ref - Sets the total integrated power (in dBm) used for the power reference.

This value is used when Power Reference is set to Manual and Reference Power Selection is set to Integrated Power.

Default: 0 dBm

Detector for Carriers - Sets the spectrum detector to use for carriers power measurement.

Changing this value may change the MeasSetup > Detectors... setting.

Choices may be limited by what is supported by the current input configuration.

Default: Average

Choices: Average, Peak (Max)

PSD Reference - Sets the PSD power (in dBm/Hz) used for the power reference.

This value is used when Power Reference is set to Manual and Reference Power Selection is set to PSD.

Default: 0.0 dBm/Hz

Detector for Offsets - Sets the spectrum detector to use for offsets power measurement.

Changing this value may change the MeasSetup > Detectors... setting. Changing this value affects behavior of Offset Res BW.

Choices may be limited by what is supported by the current input configuration.

Default: Average

Choices: Average, Peak (Max)

Peak Power Reference - Sets the peak envelope power (in dBm) used for the power reference.

This value is used when Power Reference is set to Manual and Reference Power Selection is set to Spectrum Peak.

Default: 0.0 dBm
