Short Name: Scrambler Seed

Property of niWLANAnalysis

Specifies the scrambler seed for combined signal demodulation. To reduce the test time, you must set the scrambler seed while generating a signal from the device under test (DUT).

The following table lists the valid values you must use for this property:

Scrambler Seed setting on DUT Valid Value for the Scrambler Seed property Comments
During the Creation of the Reference Files During OFDM Demod Measurement
S S S or -1 DUT scrambler seed is fixed for all WLAN packets to a particular value during both creation of reference files, and the OFDM Demod measurement.
S i S i -1 DUT scrambler seed changes from packet to packet. Scrambler seed for the received packet is estimated while performing the OFDM Demod measurement.
S i S S DUT scrambler seed changes from packet to packet during the creation of reference files. However, during the OFMD demod measurement, DUT scrambler seed is kept fixed.

where S is the fixed seed value, and S i is the varying seed value.

Note  The measurement time is the lowest when the scrambler seed value is a fixed value during OFDM Demod measurement.
