Center Freq in bladeRF-cli Vs Bin file
Posted: Sun Jul 31, 2022 10:38 am
Hope this is not a dumb question, but...
When you "set frequency" via bladeRF-cli, what are you actually doing? Does this, along with "set bandwidth," set up filters in the RF front end?
The reason I ask is the following. I can "set frequency" via bladeRF-cli to 920MHz, but then TX using a bin file where I've created an IQ signal at 915MHz. When I enable transmit, I see only the 915MHz signal on the signal analyzer. So my guess has been that "set frequency" is really just setting up the filters in the RF front end to allow signals near that "set frquency" freq to be transmitted or received.
Am I guessing correctly, or is there more to it?
Thx much!
