I would like to sweep through a band of several hundred MHz with the pluto but am unsure on two issues:
1) Is there a way to speed up the LO change,
2) Can a command port be added to the pluto source block (akin to to the USRP block) to facilitate this change within GNU Radio companion
Apologies if I have not added enough detail, I am relatively new to this area - please ask questions to help clarify.
I have managed to implement the single parameter update suggested on another post in this forum, which appears to be working perfectly!
Do you still have open questions?
I'm still struggling with how to sweep the pluto's LO automatically from within GNU radio
You can update the LO frequency using the IIO Attribute Sink block, but be aware there will be no tight relation to the data passed to the Pluto Sink block and this frequency. This is true with other radio devices like a USRP.
I'm not sure how to use the attribute sink block. Could you outline the appropriate parameters for updating the pluto's rx LO using this block? I have an OOT block sending frequency messages, which I assume I can connect to the input of the attr sink, but I am a bit lost after that. Apologies for being rather clueless.
