• In Modulation Analysis measurement, added SCPI remote command-only support for allowing Fast Mode for EVM Optimization with the Optimization method = Normal that manually sets input power level and bypasses power acquisition at the test port

• In Modulation Analysis measurement, restored once removed 4096QAM demod support (in A.38.xx) back with N9077EM1E/2E (and N9077EM3E/4E) licenses because of clearance of IVL (2024.0801)

• Support EVM optimization look-up table for N9042B UXA with V3050A Signal Analyzer Frequency Extender

• Reconstructed Edit RU Allocation settings and also supported the GUI for 802.11be (2023.1201)

• Corrected Spectral Flatness to measure active RU only (XSA-38930)

• Added support for Preamble Power measurement results (2023.0801)

• In Modulation Analysis measurement, 320 MHz Add Gamma Phase Rotation selection setting, with default +1,-1,-1 (faster than Auto Detection) (2023.0801)

• Fixed issue that caused the Gate Polarity value set in other measurements to not be applied to the Monitor Spectrum measurement (XSA-30900)

• Corrected Offset Limit settings in SEM measurement for 802.11ac preset values (XSA-35797)

• In Modulation Analysis measurement, corrected the data rate for 802.11p 10 MHz when Radio Standard is Auto (XSA-34241)

• Modulation Format preset to “SIG Syms”

• Meas Interval preset to 16 symbols (instead of 60 symbols)

• Result Length and Max Result Length preset to 16 symbols (instead of 60 symbols)

• Symbol Clock Error Compensation coupling setting to ON when switching to 802.11be

• Used common name for 802.11ax/be Demod Info file template for manual RU allocation configuration

• Added a new demod parameter “Min Idle Time” for Burst Detect Window Length, to handle signals with less than 1us idle part (2023.0301)

• Added new setting of Power Reference Plane to switch RF and Baseband in WLAN. Requires license for N9030B-BBA or N9020B-BBA, as appropriate

• Supported non-HT duplication mode in preamble puncture PPDU (2023.0301)

• Added 802.11be SEM masks for puncturing mode (2022.1201)

• Added support of cross-correlated EVM (ccEVM) on 2x N9021B MXA, 2x N9030B PXA, and 2x N9032B PXA signal analyzers (2022.1201)

• Added support of look-up table method for Optimize EVM on N9021B MXA analyzers with Opt 532, 544, or 550 (2022.1201)

• Support EVM calculation using ideal reference signal

• Support ccEVM (Cross-Correlated EVM) with two N9042B UXA analyzers for better EVM floor

• Support WLAN 11be EHT 320MHz Gamma phase rotation

• Redesign U-SIG and EHT-SIG info for 802.11be 320 MHz signals

• IEEE 802.11be updates

  • Support non-HT duplicated signal as auto detection

  • Support trigger-based signal RU allocation auto detection

  • Add unused tone error result in WLAN EVM measurement

• Common to 802.11

  • Optimize EVM with new “iteration” method

  • Display speed improvement for IQ Polar diagram

  • Support Burst Info view with per-symbol power (802.11a)

• Improved Optimize EVM feature to work better on an analyzer that does not have a preamp option

• Fixed issue in Modulation Analysis measurement that resulted in the Trigger Holdoff feature to not operate properly when Holdoff Type is set to Above or Below (XSA-24198)

• Added support for 802.11be standard draft 1.0 June 2021

• Added following features:

  • EHT PPDU DL OFDMA with MRU and MCS 14/15 support

  • EHT PPDU DL/UL MU-MIMO support

  • EHT TB PPDU support

  • PSDU CRC and data decoding support

• Added support for Non-HT demodulation of 802.11be 320 MHz signals when Radio Standard Detection is set to Auto

• Fixed issue in Modulation Analysis (EVM) measurement that resulted in a crash when an auto-saved view was being either saved or recalled (XSA-20938)

• Fixed issue in CCDF measurement that caused the Gaussian trace to disappear when switching to other measurement such as Channel Power or ACP and then returning to CCDF. This is GUI-only issue; remote operation is OK (XSA-12133)

• Auto-detection of WLAN formats including 802.11b (non-OFDM) and new 802.11be

• Support 802.11be spectral flatness measurement

• Support 802.11be User Information in EHT-SIG & Common Field
