QCM-QRM

The QCM/QRM module is responsible for adding the parameters to a single Pulsar or a single module of a Cluster using add_qcodes_params() and QcmQrm respectively. The resulting parameters are module type dependend and are described at the bottom of this page. Each module also adds the parameters for 6 sequencers, the parameters of which are described in Sequencer.
