IQ Correction (`iq_corrector_xs`)

Ettus x310 IQ Correction worker.

Design

This worker provides IQ and DC correction coefficients to a stream of i and q data.

This worker is controlled by the drc_x310.rcc worker, which accesses all of its properties.

Interface

The interface of the iq_corrector_xs.hdl worker is defined in ../specs/iq_correction_xs-spec.xml

</ComponentSpec>

Opcode handling

The both the transmit and receive data stream ports of the DRC use protocol complex_short_timed_sample-prot.xml Transmit (DAC) data streams ignore all opcodes except sample. Receive (ADC) data streams can produce Discontinuity OpCode (dependent on the setting of DRC property report_data_loss)

Properties

The properties of this worker can be found in ./iq_correction_xs.xml These properties are used by the drc_x310.rcc and do not need to be set by an application using the drc_x310. If you want manual control of the iq correction this can be done with the drc_x310.

Ports

The iq_correction_xs.hdl worker has one input and one output port.
