6.4.4. Proprietary data transfer protocols
By using the RigExpert IT-24, it is interesting to study signals with parameters not
known in advance.
The tester was placed near the car alarm RFID transmitter/receiver, operating
somewhere at 2.4 GHz. A group of short signals appear at different frequencies
periodically (every 20-30 seconds) – see the first screen shot (a waterfall mode). These
signals are better visible in the peak and average mode (see the second screen shot).
