R&S FS-K96/-K96PC Improvements

Release Notes 1310.9022.00 - 01 14

4 Improvements

The following table lists the improvements and indicates the version in which the issue

was observed for the first time:

Version

Function

V3.4 Improved the frame synchronization for continuous signals with large data

constellations, e.g. DOCSIS signals

V3.4 Improved the channel estimation for signals with highly irregular pilot

distribution, e.g. truncated DOCSIS frames

V3.4 Solved installer conflicts with 3rd party VISA software

Improvements from previous versions:

Version

Function

V3.3 The R&S FS-K96 did not accept the R&S FSVR as capture source. This

issue is solved. The R&S FS-K96PC was not affected.

V3.2 TRACe[:DATA]? remote control output for EVM vs Carrier and EVM vs

Symbol traces were scaled different from the displayed traces. This issue

is solved.

V3.2 Auto levelling for wide bandwidth signals with high power on the R&S FSW

Signal Analyzer has been improved.

V3.1 Optimization for OFDM signals with high spectral efficiency (few guard

carriers) – relevant mainly for FSQs with the B72 option

V1.0 Increased accuracy of the channel estimation. In rare conditions, not all

pilot cells were considered for channel estimation.

V1.0 Constellation diagram “pumping” during continuous measurement

V1.0 Out of memory for large constellations (>256 QAM)

V1.0 No frequency error calculation for special configurations

V1.0 EVM vs. Symbol mean trace missing for symbols with Don't Care Cells

V1.0 IF filter bandwidth setting too high if adjustable channel filter is used
