Demodulator

The Test Set has 3 operation modes within the Analyzer Mode. With Demodulator CW it is a tuned receiver and can measure only the frequency offset and average power of the input signal. With the Demodulator set to Bluetooth, a Bluetooth signal can be measured without establishing a link enabling additional measurement capability.

• Default: CW.

• Options: CW, Bluetooth 1.x and Bluetooth 2.0.

• Save Recall Settings: The value is saved as part of the configuration (.gma) file.
