Tx and Rx at different sample rate
Posted: Wed Mar 08, 2023 9:47 am
Hello!
Is there any way of transmitting and receiving simultaneously on the BladeRF micro 2.0 at different sample rate?
I want to transmit a narrow band signal (say 1MHz) but receive a complete view of the spectrum say (40MHz), without saturating the USB connection. I use the bladerf-cli repeat=0 mode to start the transmission and then I start the reception.
But when the reception starts, the sample rate of the transmission gets modified to the sample rate of reception because the AD9361 has only one BBPLL. Is there any workaround aside from setting the same sampling rate for Tx and Rx? Like a multiplayer/divider that I can set only for the Tx or Rx channels?
I am asking this because I haven't seen this restriction anywhere, hence I may be doing something wrong or missed the documentation page.
Thanks!
