3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
Auto Setup
GUI only, no SCPI command.
When Auto Setup is selected, the current sweep is aborted, and a full measurement
will be performed. The results of the measurement will be used to determine the
following settings:
Ref Value, Scale/Div, Ref Position of Y Scale of Demod Waveform, RF Envelope, Raw
Demod Waveform, and Freq Drift;
Demod Waveform Time and Demod Waveform Offset;
Ref Value, Width, and Ref Position of X Scale of Freq Drift;
Ref Value, Scale/Div, and Ref Position of X Scale of Raw Demod Waveform and RF
Envelope (when the trigger source isn’t Free Run);
Coding Rate, Payload CRC Enable, and Data Length (Byte) (when the decoder is
ON).
3.3.8.2 Meas Standard
This tab contains controls for setting the standard based on which the current
measurement is made. The standards include ZigBee (IEEE 802.15.4), Z-Wave (ITU-
T G.9959), LoRa
TM
(CSS) and HRP UWB.
Certain measurements do not support all four standards (see the compatibility table
in "Radio Standard" on page 1711). When selecting a radio standard unsupported
by the current measurement, a warning indicating a conflict of settings will appear
on the user interface.
Radio Standard
Indicates the standard on which the measurement will be made. This parameter is
removed from the GUI controls as of XA25 and the SCPI command is kept for BWC.
The three available standards are:
ZigBee (IEEE 802.15.4) It’s defined in IEEE 802.15.4 standard
Z-Wave (ITU-T G.9959) It’s defined in ITU-T G.9959 standard
LoRa
TM
A proprietary modulation schemes owned by Semtech
HRP UWB It’s defined in IEEE 802.15.4 standard
All three choices are enabled for all measurements although it is not necessarily the
case that each measurement supports all three standards. Refer to the "Standard
Compatibility" on page 403 table below for the information in detail.
