Band Table (Bluetooth Spectrum)

The Band Table trace reports the emissions limit test band by band, one row per measurement band, on the same 1 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second. grid the Band Power trace plots. This is the table that carries the per-band conformance result.

The table lists only the bands the acquisition covered. Each row carries its true band index, so a row is still identifiable when the listing is trimmed.

**Band Table Columns**
Band	The measurement-band index. For LE, band n is centered at 2401 + n MHz.
Center Freq	The band's center frequency.
Power	The power measured in the band, in dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer (or dBm/Hz when Power Calculation is set to PSD Power Spectral Density: See power spectral density.).
Limit	The limit in force for the band, taken from the tier the band's offset from the carrier selects. Absolute limits are shown in dBm; a carrier-relative mask is shown in dB.
Margin	Limit minus power, in dB. A negative margin means the band exceeded its limit.
Pass/Fail	The band's verdict: PASS, FAIL, or *** when the band was not limit-tested.

Bands That Are Not Tested

A verdict needs both a measured power and a limit, so a row reads *** for any of three reasons:

The band lies outside the acquisition span, so it was not measured.
The band is the carrier band or one of its guard bands.
The specification skips the band. The in-band emissions procedure excludes the transmit frequency and its immediate neighbors — three bands on LE 1M and seven on LE 2M — so no limit applies to them.

Individual FAIL rows do not necessarily make the measurement fail. The specification allows a limited number of exception bands, so the overall verdict in the Summary can read PASS while rows here read FAIL. The Summary's Exception Bands row reports how much of that allowance was used.
