DESCRIPTION

The dfe_test utility is used to perform a quality control test on South Coast Science digital front-end (DFE) boards. The test exercises all of the ADCs and connectors.

The output of the test is a JSON document, summarising the result of each of a series of tests.

Ideally, a standard resistor load should be attached to the AFE connector of the DFE before the test is run.
