B.2.2 BAP Mode Limitations
The minimum input level is -40 dBm (average); the minimum pulse repetition frequency is 20 Hz. If the
input signal does not meet these minima,
BURST AVG LED will flash to indicate that the input is not
suitable for BAP measurement. The power meter will continue to read the input but the BAP
measurement algorithms will not be able to synchronize to the modulation of the input; the input will
