This topic describes the Signal Optimizer's default Favorite Settings for the Custom OFDM measurement format.
Enter the name of the resource block.
Enter a description of this measurement.
When enabled (default state), this parameter conveniently couples the measurement definition to the Selected Signal. Coupled parameters may update when Download All Signals or Run Acquisition executed. This parameter is available under Advanced for all measurement types. It does not appear under Favorites unless manually added.
Select the signal definition to be applied when Signal Coupling is enabled. This parameter is available under Advanced for all measurement types. It does not appear under Favorites unless manually added.
Enable or disable coupling of Measurement Center Frequency and Measurement Span to Analyzer Hardware Center Frequency and Analyzer Span.
Enter offset to apply to automatically determined measurement Center Frequency setting when Frequency Coupling is enabled.
Enter scale factor to apply to automatically determined measurement frequency span setting when Frequency Coupling is enabled.
Enter measurement center frequency when Frequency Coupling is disabled. When Frequency Coupling is enabled, measurement center frequency is automatically determined by Analyzer Hardware Center Frequency and Center Frequency Offset settings.
Enter measurement frequency span (bandwidth) when Frequency Coupling is disabled. When Frequency Coupling is enabled, measurement span is automatically determined by Analyzer Hardware Span and Span Scale Factor settings.
Enable automatic adjustment of Frequency Step value.
Displays the measurement resolution bandwidth (RBW).
Displays the number of unaliased frequency points to display. Should be set to p2/1.28 + 1, where p2 is a power of 2.
Enable automatic adjustment of Frequency Points value to allow for a wider range of Resolution Bandwidths (and therefore time record lengths).
Enter the FFT length used for OFDM transmission. The value must be even. Usually the value is a power of two.
Range: 4 - 16384
Enter the guard interval (also called cyclic prefix), specified as a fraction of the OFDM FFT length. The value is unitless (not percent). The value is ignored if Modulation Scheme is FBMC.
Enter the number of lower guard subcarriers. These subcarriers will be ignored - they will not appear in any results, the modulation and resource type are undefined.
Range: 0 - FFT Length / 2
Enter the number of upper guard subcarriers. These subcarriers will be ignored - they will not appear in any results, the modulation and resource type are undefined.
Range: 0 - FFT Length / 2
Enable or disable display of EVM values in percent. When disabled, EVM values are displayed in dB.
Enable or disable use of data subcarriers to help train the equalizer.
Enable or disable use of pilot subcarriers to help train the equalizer.
Enable or disable use of preamble subcarriers to help train the equalizer.
Enable or disable whether to use a burst (pulse) search to locate the start of the signal to analyze.
Select the modulation scheme for the analyzed signal.
Choices: OFDM | F-OFDM | FBMC
Select the multiple access scheme for the analyzed signal.
Choices: None | SCMA | NOMA
Enter the OFDM FFT sample rate.
Enter the number of symbols to be processed during demodulation.
Enter the amount of data over which a search is performed when Pulse Search is enabled.
Select the synchronization mode used when synchronizing to the signal. The value is ignored and Time Correlation is used if Modulation Scheme is set to FBMC.
Choices: Time Correlation | Cyclic Prefix
Enter the measurement main time length.
