3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
Raw Demod Waveform: 5
Frequency Drift vs Symbols: 6
Example
:DISP:LORA:WIND:TRAC:Y:RLEV 20 dBm
Couplings The reference values of the raw demod waveform window and the demod waveform window are
coupled with the LoRa BW. The value is reset to 0 whenever the LoRa BW changes
Preset
1 RF Spectrum 0 dBm
2 Demod Waveform 0 Hz
3 AF Spectrum 100 kHz
4 RF Envelope 10 dBm
5 Raw Demod Waveform 0 Hz
6 Frequency Drift vs Symbols 0 Hz
State Saved Saved in instrument state
Min/Max
1 RF Spectrum -170 dBm / 23 dBm (CXA/EXA)
-170 dBm / 30 dBm (Other models)
