DSSS Demod:Results:80211b Peak EVM:Minimum (%) Property

Short Name: 80211b Peak EVM Minimum (%)

Property of niWLANAnalysis

Returns the minimum of 80211b peak EVM measurements, as a percentage.

Note  If you set the DSSS Maximum Chips Used property to a value less than 1,000, the 80211b Peak EVM Minimum property returns NaN. If you set the DSSS Maximum Chips Used property to -1 and the actual number of chips present in the signal is less than 1,000, the 80211b Peak EVM Minimum property returns NaN.

Note  For direct sequence spread spectrum (DSSS) demodulation, if you set the DSSS Equalization Enabled property to False, and the reference pulse-shaping filter type and filter coefficients do not match the filter configuration of the device under test (DUT) or generator, you may notice EVM degradation. Ensure that the pulse-shaping type and pulse-shaping coefficient settings match the input signal settings.

Note  If the pulse-shaping filter coefficient is less than 0.2, DSSS EVM may show degradation.

Refer to the EVM Computation for DSSS Signals topic for more information about EVM.
