Detect Non-HT PPDU
Used to control whether to detect non-HT PPDU when Radio Std is 11ax/11be.
When Detect Non-HT is Off, analyzer will not detect non-HT PPDU, just demode
signal as HE or EHT PPDU. When Detect Non-HT is On, analyzer will detect non-HT
PPDU first, if it’s non-HT PPDU, demode signal as non-HT PPDU, otherwise just
demode signal as HE or EHT PPDU.

Demod Using Reference Symbol
The reference symbols (constellation points) used in making an EVM measurement
are usually recovered from the received signal. However, if the signal quality is not
sufficient for the reference symbols to be recovered from it, you can specify the
reference symbols to be used instead. This feature allows you to choose one or the
other of these options.
If ON is selected, you will need to set (or load from a file) the necessary reference
symbols, and the measurement will use those values to calculate EVM. Total
Reference Symbols (displayed under the menu key for this feature) shows the
number of reference symbols currently set. To set the reference symbols directly,
see Set Reference Symbols (SCPI only) .To load the symbols from a file, see Recall
Reference Symbols@1600057.
If OFF is selected, the reference symbols will be recovered automatically from the
received signal.
Total Reference Symbols (displayed under the menu key for this feature) shows the
number of reference symbols. If there are none.
