-<b>&#9888; LimeSuite library is difficult to implement due to the lack of documentation. The plugins should work normally when running as single instances. Support of many Rx and/or Tx instances running concurrently is experimental and not actively supported.</b>

-Sometimes changing parameters in one instance or stopping/starting it will make the other fail or block everything. If you are lucky enough and don't change the configuration too much you may make it work but generally this is not reliable.

 This is the sample rate at which the DAC runs in kS/s (k) or MS/s (M) after hardware interpolation (8). Thus this is the host to device sample rate (10) multiplied by the hardware interpolation factor (8).
 
+☞ Note that changing the hardware interpolation factor (8) or the host to device sample rate (10) may change the ADC clock sample rate and therefore the Rx side hardware decimation factor and/or device to host sample rate. In fact ADC and DAC sample rates can be equal or related by a factor of 2.

 This is the baseband sample rate in kS/s before interpolation (9) to produce the final stream that is sent to the LimeSDR device. Thus this is the host to device sample rate (10) divided by the software interpolation factor (9).
