As of version 2.2, N7617B Signal Studio for WLAN changed support for N7617A and ESG Opt 417. Unless there are new features in v2.2 important for your application, you should continue to use the older version. If you do update to v2.2 software, you cannot playback the new waveforms created by v2.2 software unless you upgrade to N7617B license. Note you can still playback the waveforms created using v2.1 or older versions of software. Please contact factory for upgrade information.
For 802.11ac, added the support for non-HT transmission.
For 802.11ac, added the support for beamforming matrix.
For 802.11ac, added support for Minimum MPDU Start Spacing.
Implemented new license for Option Hxx, Update to 802.11a/b/g/j/p and 802.11n, which enables the following features:
For 802.11n, added the support for LDPC encoding.
For 802.11n, added the support for Minimum MPDU Start Spacing.
For both 802.11n and 802.11a/b/g/j/p, added the support for user-defined PN seed.
For 802.11n basic mode, added a new GUI parameter, Scrambler Initialization.
For 802.11n, the name on GUI, Total Length per Frame, is changed to MPDU Length.
For 802.11ac, the name on GUI, MAC Frame Length, is changed to MPDU Length.
For 802.11n, the ‘Signal Configuration’ parameters failed to refresh on some PCs when the Format was changed in the ‘Waveform Setup’ node.
For 802.11ac, the Aggregated Mpdu was incorrectly turned on when recalling a setup file saved with software version 1.7.
When recalling a setup file with a PPDU format other than the one in the current setup, an error message was displayed saying "There is an error in the XML document."
The values in CCDF data table were not correct.
802.11ac waveforms had a different delay from the Event 1 (marker 1) output to the start of RF output when using software version 1.9, versus 1.7.
For 802.11ac, the delay from the start of the Event 1 marker output to the start of the RF output was different when a root-raised cosine filter was on versus off in software version 1.9. However, the delay was the same for these cases in version 1.7.
When playing back an 802.11ac waveform file, using single sweep with external trigger, the power with ALC on was sometimes unstable.
VHT-LTF and VHT-SIG-B were generated incorrectly when the number of space-time streams was 5 or 6 due to an error in Matrix PVHTLTF.
Added support for the M8190A Arbitrary Waveform Generator.
Added support for the M9381A PXI Vector Signal Generator.
Added support for the M9252A DigRF Host Adapter.
Added support for a mix of N5182A/B MXG or N5172B EXG signal generators for WLAN 802.11ac MIMO and 80+80 MHz setups.
Added Trigger button to instrument control page.
Improved the CCDF display.
Added support for WLAN 802.11ac operation in the TVWS spectrum.
Improved WLAN 802.11ac channel models for fading impairments.
Increased maximum data length for WLAN 802.11ac.
Increased MIMO support for WLAN 802.11ac to up to 8 antennas using EXG or MXG signal generators.
OFDM windowing was applied across PPDU frame boundaries.
The default value for Perform DC I/Q Calibration was changed from Off to ON.
The maximum value for Oversampling Ratio was changed from 16 to 64.
The maximum value for Number of Frames was changed from 16 to 2000.
Two parameters, “RF Burst Duration in One Frame” and “Overall Waveform Duration in One Frame,” were added to indicate the waveform duration.
Software version 1.0.5.0 is the initial release of N7617B Signal Studio
for WLAN 802.11a/b/g/n/ac (formerly named 802.11 WLAN) and is used to generate WLAN MAC and PHY standard-compliant
waveforms for component or receiver test.
