Selected (See MB-OFDM Standard Setups/Presets Table.)
When is selected for Result Length, the VSA automatically determines the measurement by comparing the PSDU 1) PHY Service Data Unit, or 2) PLCP SDU (payload) Length in the Header (displayed in Header Info Data trace) to the Max Result Length and using the smaller value.
If the is greater-than the PSDU Length, the measurement result length will default to the PSDU Length detected in the Header. If is less-than or equal to the PSDU Length, the measurement result length is set to the .
If there is a failure in decoding the header, the measurement result length is set to 12 symbol-times causing only the header to be analyzed.
