1 or not
specified
Returns scalar results:
When the radio standard is not 802.11ac 80 + 80 MHz or 802.11ax 80 + 80 MHz:
Channel Power
A floating-point number representing the total channel power in the specified integration bandwidth
Peak PSD (Power Spectral Density)
The peak PSD over the integration bandwidth. The unit bandwidth is selected by "PSD Unit" on page
628 in either dBm/Hz or dBm/MHz
Mean PSD (Power Spectral Density)
The mean PSD over the integration bandwidth. The unit bandwidth is selected by PSD Unit in either
dBm/Hz or dBm/MHz
When the radio standard is 802.11ac 80 + 80 MHz or 802.11ax 80 + 80 MHz:
Channel Power of the carrier of which the center frequency is indicated by Freq Segment 1
A floating-point number representing the total channel power of the first segment in the specified
integration bandwidth
Peak PSD (Power Spectral Density) of the carrier of which the center frequency is indicated by Freq
Segment 1
The power in the specified unit bandwidth of the first segment. The unit bandwidth is selected by PSD
Unit in either dBm/Hz or dBm/MHz
Channel Power of the carrier of which the center frequency is indicated by Freq Segment 2
A floating-point number representing the total channel power of the second segment in the specified
integration bandwidth
Peak PSD (Power Spectral Density) of the carrier of which the center frequency is indicated by Freq
Segment 2
The power in the specified unit bandwidth of the second segment. The unit bandwidth is selected by
PSD Unit in either dBm/Hz or dBm/MHz
Mean PSD (Power Spectral Density) of the carrier of which the center frequency is indicated by Freq
Segment 1
The power in the specified unit bandwidth of the first segment. The unit bandwidth is selected by PSD
Unit in either dBm/Hz or dBm/MHz
Mean PSD (Power Spectral Density) of the carrier of which the center frequency is indicated by Freq
Segment 2
The power in the specified unit bandwidth of the second segment. The unit bandwidth is selected by
PSD Unit in either dBm/Hz or dBm/MHz
2 Returns floating point numbers that are the captured trace data of the power (in dBm/resolution BW) of the
signal for Trace 1. The frequency span of the captured trace data is specified by "Span" on page 614
