3 Short-Range Comms & IoT Mode
3.3 LoRa (CSS) Demodulation Measurement
NOTE
Pressing the peak search hardkey will navigate the menu to the peak search
page and perform a peak search if the previous menu wasn’t of markers.
Marker Frequency|Time
Sets the X-axis position of the specified marker on the trace. This is the same as the
"Marker Frequency|Time" on page 386 in the Settings tab.
Peak Search
Moves the specified marker to the trace point that has the maximum y-axis value.
Remote
Command
:CALCulate:LORA:MARKer[1]|2|...|12:MAXimum
Example
:CALC:LORA:MARK2:MAX
:SYST:ERR?
can be used to query the errors to determine if a peak is found. The message “No peak found” will be
returned after an unsuccessful search
Next Peak
Moves the specified marker to the peak that is next lower in amplitude than the
current Y-axis value. Only peaks that meet all enabled peak criteria are considered.
If there is no valid peak lower than the current marker position, a “No peak found”
message is generated, and the marker is not moved.
If the selected marker was off, then it is turned on as a normal marker and a peak
search is performed.
Remote Command
:CALCulate:LORA:MARKer[1]|2|...|12:MAXimum:NEXT
Example
:CALC:LORA:MARK2:MAX:NEXT
State Saved Not part of saved state
Minimum Peak
Moves the specified marker to the minimum y-axis value on the current trace.
Minimum (negative) peak searches do not have to meet the peak search criteria. It
looks for the lowest y-axis value. If the selected marker is Off, it is turned on before
the minimum search is performed.
