Hi there! I’m an uber noob when it comes to SDR and especially LimeSDR. I have a LimeSDR-mini and wish to simply set a particular transmit power and frequency to then measure raw IQ from the receiver. Right now I have the TX directly connected to RX with a 10dB attenuator.
What is the easiest tool to use to accomplish this? GRC? LimeSuiteGUI? SoapySDR backend? I don’t need to do any processing of the data on the MCU or anything. If I can get raw IQ via python or something that would be ideal.
Ideally I would also like to do the following:
- calibrate transmitted power? is this possible with onboard hardware? Obviously setting the gain is pretty easy but is there an easy way to know what the output power is at TX port with reasonable accuracy?
- Quickly sweep a particular frequency range. I have tried to look up some discussion on this, and it seems like this might be pretty difficult.
- Bonus points: has anyone performed TDR measurements using a LimeSDR? How doable is this?
I’m not really asking for anyone to figure this out for me obviously. BUT if you have any advice or know if any of this is doable PLEASE let me know!
