Advanced Settings (6GR)
The section of the Advanced tab holds additional analysis controls. All parameters are auto-coupled — see Auto and Manual Parameter Coupling.
Span To Min BW Ratio - The ratio of the measurement span to the minimum signal bandwidth.
Default: Auto — adjusted to the signal (nominal 1.2)
Range: 0.1 to 20
Channel Response Per Slot - Computes the channel frequency response per slot instead of as a single combined result. Affects the OFDM Eq Ch Freq Resp trace.
Default: Cleared
DC Punctured - Indicates that the signal's DC subcarrier In an orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signal, the subcarrier whose frequency would be equal to the RF center frequency of the station. is punctured.
Default: Cleared
Multicarrier Filter Enabled - Enables the multicarrier filter.
Default: Cleared
Low SNR Signal-to-Noise Ratio Mode - Optimizes the analysis for low signal-to-noise-ratio conditions.
Default: Cleared
IQ Imbalance Est Mode - Selects how IQ imbalance is estimated.
- Off - IQ imbalance estimation is off.
- Per Carrier - IQ imbalance is estimated and averaged over each component carrier.
- Per Subcarrier - IQ imbalance is estimated on each subcarrier.
Default: Off
Choices: Off, Per Carrier, Per Subcarrier
Compensate IQ Imbalance - Compensates for measured IQ imbalance. Only available when IQ Imbalance Estimation Mode is not Off.
Default: Cleared
Compensate IQ Offset - Compensates for measured IQ offset.
Default: Cleared
CCDF Complementary Cumulative Distribution Function Data Source - Selects which data parts are included in the CCDF calculation and the Time/Spectrum trace display.
- All - All data within the measurement interval is included.
- Enabled Channels - All physical channels enabled within the measurement interval are included.
- EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. Included Channels - All physical channels enabled and also included in the EVM calculation within the measurement interval are included.
Default: All
Choices: All, Enabled Channels, EVM Included Channels
Test Environment Condition - Selects the environmental condition assumed by the analysis.
Default: Normal
Choices: Normal, Extreme
Uplink Spectrum Flatness / UL Up Link (reverse link: from cell phone to base station) Spectrum Flatness Tolerance - Two related controls: is the enable toggle for uplink spectrum flatness evaluation, and is its test tolerance in dB.
Default: toggle Auto — enabled when any enabled carrier's link direction is Uplink; tolerance 1.4 dB
Range (tolerance): -100 to 100 dB
