monitor_xs HDL Worker

Ettus x310 channel monitor worker.

Detail

This worker does not have any subdevices. It takes in an iq data stream accumulates the samples, storing the results in its properties.

This worker is controlled by the drc_x310.rcc worker. An application is expected to read the i_value, q_value, and data_valid property of the worker.

The data_valid signal should always be checked before reading i_value or q_value, as otherwise they may contain arbitrary data. If the data on the channel is disrupted, for example due to retuning, changes in receive setup etc… then it is also advisable to throw away the value the first time data_valid is asserted.

If you read just one value, for example just i_value, then the worker will store the matching q_value until it is also read. This is to avoid an ACI application reading values that were actually taken from different samples.

This worker does not drive any GPIO, SPI or LED signals.
