Examples Of Channel Power Measurement Capabilities - Berkeley Varitronics Systems BumbleBee-TABLET Manual

4.3 Power Trigger Mode:
The Power Trigger Mode is a useful mode, in which, the receiver triggers only when the channel power
exceeds a certain threshold, which is set by the user. If the user has set a value for the measurement delay,
the receiver will take measurements only after that delay time. The device will trigger when the detected
channel power exceeds the set power threshold. This mode is useful in detecting activity from non-
continuous transmission sources such as Beacon packets from an AP or Frequency Hopping Spread
Spectrum (FHSS) Packets from a Bluetooth device or any other Narrow band or CW signal.
Important Note: The trigger mode can be set only for a 20 MHz channel.
