Modular Multi Source

At a Glance

Maximum flexibility, highest precision – all in one system: The Modular Multi Source (MMS) combines numerous laboratory sources in a compact benchtop solution, creating a new level of efficiency for everyday laboratory work.

Thanks to its innovative plug-in card system, the Modular Multi Source can be individually adapted to your requirements. Whether current sources, voltage sources, Source Measure Units (SMUs), TEC controllers, or laser drivers – you can combine exactly the functions you need in one powerful system. This makes the Modular Multi Source ideal for applications in electronics development, optics and photonics, component and system characterization, semiconductor research, and communication technology.

Despite its versatility, the MMS remains a cost-efficient high-precision solution. It not only reduces investment costs, but also minimizes cable clutter in laboratory setups: instead of using multiple individual devices, you can access up to 48 channels centrally through a single signal output.

Operation is just as flexible as it is precise: all channels can be synchronized and controlled via an SCPI interface or through our intuitive GUI – even across multiple connected devices. This ensures full control over your measurement and experimental setups at all times.
