3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
Marker Frequency|Time
Sets the X-axis position of the selected marker on the trace. This is the same as the
"Marker Frequency|Time" on page 386 in the Settings tab.
Mkr->CF
Sets the center frequency of the analyzer to the frequency of the specified marker.
The marker stays at this frequency, so it moves to the center of the display. In delta
marker mode, this function sets the center frequency to the x-axis value of the delta
marker.
If the currently selected marker is not on when this control is pressed, it will be
switched on at the center of the screen as a normal marker.
Remote Command
:CALCulate:LORA:MARKer[1]|2|...|12[:SET]:CENTer
Example
:CALC:LORA:MARK4:CENT
Notes If specified marker is off, this command will turn it on at the center of the screen as a normal type
marker
Dependencies This function is not available (control is grayed out) when x-axis is the time domain
Couplings All the usual couplings associated with setting Center Frequency apply
3.3.8 Meas Setup
The Meas Setup menu panel contains functions for setting up the measurement
parameters and contains functions for setting up parameters global to all
measurements in the mode.
3.3.8.1 Settings
The settings tab contains the frequently used measurement setup functions.
Average/Hold Number
When averaging is on, the RF Spectrum, AF spectrum traces and the frequency drift
vs symbol trace are averaged. In addition, four traces will be displayed on the demod
waveform window: an averaged trace, a max hold trace, a min hold trace, and the
existing demod waveform trace. All metrics are averaged, and shown on the metrics
window.
The average type varies from window to window. And the type in detail is shown in
the following table:
