Synchronised instruments

[jpsecher]

I want to make it possible for users to connect several identical instruments together to control the collective set of channels as one instrument. The specific instrument is QDAC-II, and it has special features for synchronising the clocks of several units.

What would you suggest as the best route for implementing this? Should I create something that fits in the Instrument hierarchy that delegates commands to underlying VisaInstruments?

@jpsecher Yes I think I would go that route. We don't have a close matching example in QCoDeS but perhaps the virtual driver for the AMI magents could serve some inspiration. See AMIModel4303D here In this case the purely virtual instrumnent is responible for delegating commans to 3 magnet psus to allow the user to set and get magnetic fields in various meaningful coordinate systems without having to manually perform the transformations
