Hello, I'm using gnuradio with the usrp_source block. What I'm trying to do is rapidly retune between 24 Msps and 12 Msps, and possibly other arbitrary rates too shortly.
This is easy to do with a B200 series radio using the usrp_source block and the command message port by sending a PMT message of the "rate" type. However, I'm now using an E310 and it will not easily retune. I can do 24 and 12 Msps by starting out with a 24 and 12 as the clock rate, however, the current API only allows setting the sample rate and not the clock rate during run time. Would it make sense for the E310 only to hack the usrp_source block code to set the clock rate and the sample rate at the same time? Also, I have a related question. I have tried using the RFNOC USRP block, however, this block does not have the "command" PMT message input for retuning while a flowgraph is running. And a related question is that the RFNOC block only has a master clock rate and a Bandwidth and no sample rate. Would it be safe to say the when using this block with the E310, that the sample rate and the clock rate are set to the same value always? Thanks Jack
