3.3 LoRa (CSS) Demodulation Measurement
406.25 kHz
Sets the bandwidth of the chirp signal to 400 kHz.
Example
:LORA:DEM:BAND BW406K
812.5 kHz
Sets the bandwidth of the chirp signal to 812.5 kHz.
Example
:LORA:DEM:BAND BW812K
1.625 MHz
Sets the bandwidth of the chirp signal to 1.625 MHz.
Example
:LORA:DEM:BAND BW1625K
Programmed Preamble Length
Sets number of the chirps before the sync chirps in the preamble. The unit is symbol
Remote
Command
[:SENSe]:LORA:DEMod:PPLength <integer>
[:SENSe]:LORA:DEMod:PPLength?
Example
:LORA:DEM:PPL 6
:LORA:DEM:PPL?
Couplings if the measure time auto is On, the minimum measure time can be impacted by this parameter in the
following way:
Calculating the length of the LoRa symbol based on the BW and the spreading factor
Multiplying the ideal symbol length with the sum of the programmed preamble length plus an empirical
data symbol length. The product will be further multiplied with an empirical coefficient and eventually
set as the minimum measure time
