Get amplitude values for specific frequencies

#1 · 16/03/2023, 15:53

Hello,

i want to analyze a device which has a transmitter (868Mhz).

To see the spectrum around this frequence i thought i have to set the startfrequence to 800Mhz and the stop frequence to 950Mhz.

Now, if i start the device and collect some data, i got a float array but don't know if this is the amplitude value or for which frequence this values are.

How can i get data like scannedFrequence and its amplitude value?

Thanks & greetings from germany.

As a general rule: the main array will only contain measurement values, frequencies for those need to be calculated from the header values (startfrequency, spanfrequency, stepfrequency, num and size) by the user.
