I'm using an A5, and it should have the most recent firmware, fpga, etc.
When I try to set the sample rate for an individual channel, it overwrites the sample rates for all of the channels.
Is there something I'm missing?
Here's the output from cmd:

Can't control sample rates inidvidually

Re: Can't control sample rates inidvidually
The AD9361 only has one baseband clock domain, so RX1, RX2, TX1, and TX2 are driven by the same PLL. Changing anyone one channel's sample will change every other channel's sample rate as well.
