3.3 LoRa (CSS) Demodulation Measurement
This measurement provides the capability of demodulating the LoRa
TM
signals and
displaying the demodulated signal both in the time domain and in the frequency
domain. It also provides a trace representing the frequency drift value on each
symbol and some numeric results such as Tx power, symbol rate, preamble length,
and payload length, etc.
LoRa (CSS) Demodulation Measurement Commands
Selects the LoRa demodulation measurement in measure preset state:
:CONFigure:LORA
The following commands select the measurement without affecting the settings:
:CONFigure:LORA:NDEFault
:INITiate:LORA
The following queries are used to retrieve the measurement results:
:FETCh:LORA[n]?
:READ:LORA[n]?
:MEASure:LORA[n]?
Remote Command Results
The following table displays the returned results from the
(FETCh|MEASure|READ):LORA commands, indexed by subopcode:
