The spectrum analyzer performs power measurements in the configured bandwidth.
The X-axis represents frequency in MHz and Y-axis displays actual received power.
The X-axis represents frequency in MHz, and the Y-axis displays actually received power.
In the example above, the frequency span goes from 850 MHz to 950 MHz (that is a 100MHz range), and
the visual amplitude goes from -11 dBm to -110(-139) according to the datasheet(High sensitivity: down to -148dBm) dBm.
To show the results in a plot, run the Python script
RadioLib/extras/SX126x_Spectrum_Scan/SpectrumScan.py
# Features
## Multiple Ranges Scan
Disabled By Default
```
// Feature to scan diapazones. Other frequency settings will be ignored.
int SCAN_DIAPAZONES[] = {};
//int SCAN_DIAPAZONES[] = {850890, 920950};
```
To Enable Add/ uncomment an array of the frequencies
```
int SCAN_DIAPAZONES[] = {850890, 920950};
```
where 850890 stands for 950-890Mhz range
920950 - 920-890Mhz
Other settings will be ignored if **Multiple Ranges Scan** is enabled.
## Waterfall
Waterfall showed only on One Page Scan
to disable - un comment this line
```
#define WATERFALL_ENABLED true
```
Waterfall shows the last **N** = SCREAN_HEIGHT (64) - WATERFALL_START(37) - 8 (part of the STATUS_TEXT_TOP) = **19** signal detection that excited set signal level
## Multi Screen Scan
Single screen scan for now has **RANGE / 128** resolution.
Multi-page scan can be adjusted to how many MHz per page you wanna scan
```
// frequency range in MHz to scan
#define FREQ_BEGIN 850
// TODO: if % RANGE_PER_PAGE != 0
#define FREQ_END 950
// Feature to scan diapazones. Other frequency settings will be ignored.
int SCAN_DIAPAZONES[] = {};
// int SCAN_DIAPAZONES[] = {850890, 920950};
// MHZ per page
//To put everething into one page set RANGE_PER_PAGE = FREQ_END - 800
unsigned int RANGE_PER_PAGE = FREQ_END - FREQ_BEGIN; // FREQ_END - FREQ_BEGIN
//To Enable Multi Screen scan
// unsigned int RANGE_PER_PAGE = 50;
// Default Range on Menu Button Switch
#define DEFAULT_RANGE_PER_PAGE = 50;
```
To enable Multi-page by default set **RANGE_PER_PAGE** less than **FREQ_END - FREQ_BEGIN**;
Switch to multi-page during regular One Screen application run. Restart the ESP32 on screen after the logo press the P button.
## Mute Autio Notifications
Restart ESP32, and on the logo display, press the P button.
## Pause Execution
Press P for more than 2 seconds. Execution will pause, and the scan's current Mhz position will be shown on the display.
If less, ESP32 will turn off. Fast pressing(less than 0.5 second) P button changes the notification level
