What is IQ sample rate?

There will always be a “sample rate”, the rate at which sampling is performed. Someone might say, “I have an SDR running at 2 MHz sample rate.” What they mean is that the SDR receives two million IQ samples per second. If someone gives you a bunch of IQ samples, it will look like a 1D array/vector of complex numbers.

What should be the sampling rate?

Definition: Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.

What is IQ rate in communication?

IQ rate is the sampling rate of the baseband I/Q data in samples per second (S/s). Carrier frequency is the carrier frequency of the RF signal in Hz. Gain is the Tx gain applied to the RF signal in dB. Active antenna is the antenna port to use for this channel.

What is the Nyquist sampling rate for a signal with bandwidth of 200 kHz?

The bandwidth of a low-pass signal is between 0 and f, where f is the maximum frequency in the signal. Therefore, we can sample this signal at 2 times the highest frequency (200 kHz). The sampling rate is therefore 400,000 samples per second.
