All fine my friend, no need to get upset
We are all here to learn from each other... thank you for your lessons
He is not nervous. I just want to show you what the subject of modulation analysis in general purpose spectrum analyzers looks like.
Different people read the forum and then different disappointments arise. Better to avoid it and explain it exactly.
Unfortunately, this is how it looks and it is probably dictated by the financial policy of companies producing measuring equipment, it is known that directing specialized devices to specific markets (mobile phone operators, TV operators, etc.), you can earn more.
SSA/SVA was supposed to be able to save the I/Q signal to a PC (via software Easy VSA), this information can be seen in older versions of the manual. However, it seems that for some reason they did not introduce such a possibility.
I tried to decode this is what it gives
For 2G we will say that it is OK
For 3G even though the bandwidth is 4 MHz it doesn't seem to decode anything.
In the case of UMTS (HSPA +), unfortunately it will not work, here you need more than 2.5Msps.
As for the occurrence of QAM modulation, at the moment it is difficult for me to think of something, the simplest and cheapest way is to generate QAM using SDR, e.g. ADALM-Pluto etc.
