Hello, I need to control a RF synthesizer from within a GNURadio flowchart updating some parameters on the base of some measurements obtained from processing data collected by an USRP.
The synthesizer is connected through a RS232 serial port, thus is quite slow, but the bandwidth of the control is also very small, < 1Hz. One of the parameters that needs to be controlled is the output power, and it can be adjusted only in discrete steps of 0.01 dB, therefore I need to correctly take care of the discretization. What is the best strategy to do that? Should I simply implement a sink block? Would be better to implement the discretization in a sink block that then sends messages to another block that handles the communication with the synthesizer? As far as my experimentation goes, there are no blocks using messages in the standard GNURadio distribution (version 3.7.2), therefore I don't really have examples of use cases for it. Thanks.
