bladeRF 2.0 xA5 multiple RX?

Post by devicenull »

What are the limitations when trying to use both RX inputs on a xA5? Do they both have to be using the same frequency, or can I tune to two different frequencies?

All the info I can find seems to talk about the older iterations of the hardware, so I'm not sure what's relevant anymore.

Got a link to the pages you're referring to so we can update them?
The bladeRF 2.0 micro xA5 has 2 RF PLLs, one is for RX and the other is for TX. The RX RF PLL drives both RX1 and RX2. Completely separately of the RX RF PLL, a single TX RF PLL concurrently drives TX1 and TX2. So RX1 and RX2 will always be tuned to the same channel. And likewise TX1 and TX2 will always be tuned to the same channel.
