I am just trying to run a scan, but I see very inconsistent results. Sometimes the signal is picked up fine, other times it barely picks it up or gives incorrect information. I am sending in a clean LTE signal from a base station emulator, so I don't think there is an issue with a bad input. If I use the bladeRF as a spectrum analyzer, I can see the signal is coming in just fine.
A few things I have noticed that may be contributing to the inconsistencies that I see.
- When running bladeRF as a spectrum analyzer with no signal in, I see a spike at the center frequency. Is this an issue?
- I performed automatic calibration according to this page (https://github.com/Nuand/bladeRF/wiki/D ... Correction), but I wasn't sure if the values were getting used properly. So I performed the manual calibration steps, but now I am not sure what to do with the numbers I have. I tried calibrating, closing the osmocom_fft, and then re-opening it, and the values were lost. So I don't think they persist on their own. How can I input these numbers to the OpenLTE Scan application?
- What is the input power range bladeRF can accept? What is the minimum and maximum power ranges?
- Clearly I can use the internal amplifiers to change power leve;s into bladeRF, but if I kept them static, how wide is the actual power window that the board can accept? 10dBm? 20dBm?
