Calculation Tab (Markers Properties)

The Calculation tab of the Marker dialog box configures the frequency counter and band power calculation for the active marker.

Marker controls: at the top of the Calculation tab are controls for selecting, adding, and removing markers. A marker is uniquely specified by a trace and a marker number. See Managing Markers for more information.
Frequency Counter: Select the check box to enable the frequency counter. Only one marker per trace may have frequency counter enabled.
Band Power: Select the check box to enable band power calculation.
- Type: Select between band Power or band power Density calculation types.
  
  Calculate: Select between Mean and Rms band power calculations.
  
  Band Power markers for OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. measurement types provide capabilities unique to OFDM trace data displays, see OFDM Band Power Markers.
- Center/Span: When the Show Center/Span check box is checked, Center and Span can be set for the band.
- Left/Right: When the Show Center/Span check box is cleared, Left and Right sides can be set for the band.
Analog Demod Carrier: Select the check box to display the estimated carrier for analog demod measurements. This does not work for AM Amplitude Modulation - CW modulation using amplitude variation in proportion to the amplitude of the modulating signal. Usually taken as DSB-LC for commercial broadcast transmissions and DSB-SC for multiplexed systems. modulation, and if Auto Carrier Frequency is cleared in the Analog Demod dialog box, Analog Demod Carrier shows the marker value.

This parameter is only available when the Measurement Type is set to Analog Demod.
