3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
is generated, the RMS Ratio and Ratio Ref values display --- and queries of either
return not a number (9.91 e37).
To turn off the ratio display, select one of the other modulation magnitude views.
The ratio references are saved in State, and when the recalled state of the metrics
settings is RMS Ratio, the saved reference for the current measurement should be
recalled and used, rather than establishing a new one.
Example
:DISP:LORA:VIEW:METR:MMAG RMSR
Reference Selection
Chooses the mode of setting the ratio reference. If Measured is selected, the
reference is set based on the previous measurement result, and the value is
displayed on the control of the ratio reference. Otherwise, the value displayed on the
control of the ratio reference, which can be input by the users, will be used as the
reference.
The control is only enabled when the metric settings is RMS Ratio.

Ratio Reference
Sets the RMS ratio reference’s value when the reference selection is manual, in
which case the control is enabled.
The control is otherwise disabled and only used for displaying the reference value
obtained in advance.
