Bases: MonitorControl.BackEnds.Backend

SAO 32K-channel spectrometer client

This is a DSSServer attribute item equipment['Backend']

This backend consists of four ROACH boards, each running the same firmware. It takes in four IF class signals and outputs digital data (spectra) for each channel.

The details of this class depend on the SAO spectrometer firmware in the ROACH processors.

This is a client class which uses the server controlling the spectrometer.
