Do you have unique requirements for your magnetic resonance projects, looking for a customizable NMR console ? You have a particular need for your business or just looking for technical expertise. Our teams are at your disposal to find a solution to your problems.

Contact us with your custom electronics and/or software requirements and our team can discuss options with you.


The Gecho is a modular RF chain (NMR Spectrometer (Cameleon4) + Amplifiers + Pre-amplifiers), associated with a power supply, that can be modified to meet your needs. The Gecho is assembled in a 3 U box.

The Gecho is a versatile system where one can add parts on request, such as a shim card or a gradient card.



The console has 3 transmit channels and 3 receive channels with LNA and TR switches for each one. It can be configured for simultaneous acquisition on the 4 receivers at different observation frequencies.

The adjustment and adaptation of the probes are integrated with a directional coupler on each transmission channel.

The system comes with an unlimited number of licenses on our proprietary acquisition and processing software: SPINit (running Windows). If you wish to keep your acquisition software, we also give access to the Driver, allowing you to ensure a link between your software and ours.
