Index: n Results Returned
56.
Packet Extension Duration (us) ( it will be -999.0 if radio std is NOT 11ax or 11be)
57.
Guard Interval of Trigger-based PPDU Guard Interval (us) ( it will be -999.0 if radio std is NOT 11ax or
11be)
58.
HE-LTF/EHT-LTF type of Trigger-based PPDU if radio std is 11ax/11be; it will be -999.0 if radio std is
NOT 11ax or 11be
HE-LTF Type of Trigger-based PPDU, the returned integer means:
0 1 x LTF
1 2 x LTF
2 4 x LTF
EHT-LTF Type of Trigger-based PPDU, the returned integer means:
1 2 x LTF
2 4 x LTF
59.
The minimal Meas Interval for successful PSDU CRC decoding (if the Firmware Version is below A.22.00,
it returns -999.0 which means Invalid)
60.
PSDU CRC for 802.11a/11n/11ac/11af (if the Firmware Version is below A.22.00 or it is not
802.11a/11n/11ac/11af , 1 means Fail, 0 means Pass, -999 means Invalid)
61.
Duty On Period (Unit is microseconds, it is the pulse width, if the Firmware Version is below A.30.00 or it
is not found, it returns -999.0 which means Invalid.-999.0 means invalid)
62.
Duty Off Period (Unit is microseconds, it is (pulse period – pulse width), if the Firmware Version is below
A.30.00 or it is not found, it returns -999.0 which means Invalid.)
63.
Duty Cycle (Unit is %, it is pulse width / pulse period, if the Firmware Version is below A.30.00 or (either
Duty On or Off is not found), it returns -999.0 which means Invalid
64.
Average RMS ccEVM, if the Firmware Version is below A.33.00 or Cross-Correlated EVM is off, it returns
-999.0 which means Invalid.
Here “Average” means using data of each measurement in measurement loop to calculate RMS ccEVM.
ccEVM is not accurate and can’t reflect source EVM if data point is not sufficient, use more data points
(average number * Data Points), then it can lead to a more stable and accurate ccEVM result.
It will not only benefit for the cases that data point is obviously not sufficient (small BW, small MCS, small
symbol length), for all cases, it will lead to a more accurate ccEVM result, the key point is to balance time
and improvement
65.
Valid data points that used to calculate ccEVM, if the Firmware Version is below A.33.00 or ccEVM is off,
it returns -999.0 which means Invalid
66.
Total data points that used to calculate ccEVM, if the Firmware Version is below A.33.00 or ccEVM is off,
it returns -999.0 which means Invalid
67.
Partial Burst Power Max (dBm), if the Firmware Version is below A.36 Minor or Radio Std is not
11n/ac/ax/be, returns -999.0, which means Invalid. Valid when Radio Std is 11agjp if Radio Std
Detection is auto, but invalid if Radio Std Detection is Manual
