My first set up is the IF chain alone, later on I plan to test the entire RX chain (BPF>LNA>BPF>Downdonverting mixer>BPF>AMP>IQ Demod>Modem)
Here is my current setup:

In order to measure the SNR, I'm injecting a CW at the center frequency with 1KHz offset...
Hello all,
I have a question regarding SNR measurement when using IQ Modulation:
In my design, I'm using a IQ Demodulator + IQ Modem.
The modulation type is 4QAM, at 4.8k/symbols. The receiver noise figure is 4dB, and the modem SNR requirement is 4dB in order to achieve a PER of 1%
The RX...
