Let me explain a bit back ground, long ago I used LEDs and Serial port to debug SPI, I2C communication which was quite hard. Then I came to know about Logic Analyzer, oh god it made my life so easy.
A few months back I started working on NRF24L01 modules to communicate between two uC, I gave myself a challenge to build it by getting help only from its datasheet. After setting up RX, TX nodes I had no idea if TX really transmitted anything?? this bring me to search for Spectrum Analyzer so that I know if my modules are really working.
So I started searching around for reasonable Spectrum Analyzer after reading/exploring a lot of options, I bought two devices. HackRF One and Signal Hound SA44B. Now when I transmit I do not see any signal on any of these device, that made me think may be I do not know how to use it in this scenario.
While working with logic analyzer we have trigger to make it ready to listen/log data, my question is how can I snif tranmitted packets to analyze if everything is correct? please help me what terms are used for it, what kind of procedures used so that I can further learn it. One thing I found tricky that Spectrum analyzer (at least my devices) can't continiously minitor the signal, alway there is a small gap in between a sweep how do I overcome this, because I do not have trigger like a logic analyzer to ensure SA is looking for packet right after it transmitted.
