Tiny Spectrum Analyser 600MHz to 2600 MHz

Messagede F6DZP » Mer 19 Juin 2013 06:50

Hello,

I'm working on a new tool : Spectrum Analyser that works from 600 MHz to 2600 MHz using a 48 euros PCI card : TT S2-1600

It 's just the beginning of my development, so many things remain to do.
But it can show that it works.

There are some limitations:
- Bandwidth : lowest value is 10 MHZ
- Scan speed : for a full scan (600 MHz to 2600 MHZ) it takes about 6 sec.

But it can help us for finding carrier harmonics, look at noise on a band ..

Here I show some screen captures of one of first beta version ( there is my DATV signal on 1255 MHz)

full scan Max Gain:

100 MHz scan - 1255MHz centered - BBgain 2 dB

I will put here here Free for download after having added some new functionalities.

Perhaps you can give me some ideas. Thanks.

Hello , I'm nunzio it9sak . I would like know if is possible use the board TT1600 like dvb-t costellation analyzer of a signal QAM16 @ 600Mhz dvb-t not dvb-s .

Or if exist a dedicate software which use RTL2832 SDR usb-key or internal MEDION DVB-T receiver with the chipset SAA7131

Thanks for your reply

TT S2-1600 is only for DVB-S, so you will see only QPSK constellations.

I don't know which software can do that for DVB-T with an SDR and if it exists.
