Automatic (802.11n/ac/ax/be)
Number of Spatial Streams
When is selected, the VSA uses the number of HT-LTF/VHT-LTF symbols in the preamble to automatically determine the number of spatial streams. This works in most cases but will fail on some signals which use non-square MIMO (more transmit antennas than spatial streams).
When the input signal has correct SIG symbols, you can use the From SIG Symbols setting to automatically handle all 802.11n/ac/ax/be signals, regardless of the number of HT-LTF/VHT-LTF symbols.
