Bravo MRI Analyzers :: Product

The Bravo MRI analyzers are handheld test instruments used by R&D engineers, field service engineers, installation specialists, production, and quality assurance teams to calibrate/tune MRI transmit and receive coils. They provide accurate measurements of impedance, resistance, phase angle, X, Q, return loss, and SWR. The Bravo MRI is a true Vector Impedance analyzer that accurately measures circuit impedances from 2 to 2000 Ohms. The Bravo MRI is capable of simultaneously plotting any two measurements while displaying both plot's respective Y axis scales. Circuit Q is calculated using either serial or parallel resonances. The Bravo MRI's portability and ability to be used in close proximity of the magnetic field make it the ideal test instrument for installing and servicing MRI systems. There is a Cable Nulling capability to eliminate the effects of connecting cables.

AEA Technology offers several configurations of the Bravo MRI product to satisfy your specific requirements. The Bravo MRI covers up to 70 MHz while the MRI EX unit extends the frequency range to 200 MHz. The MRI II adds S21 parameters and is the perfect tool for measuring isolation between coils.

The PC Vision Software application provides the user with the capability of remotely operating the Bravo MRI through a serial port connection while viewing Real-Time results on a P.C. The software makes the capture, storage, and printing of documentation and reports easy.

The Bravo MRI will save time, reduce capital expenditures, and improve on other costs that are typically associated with the development, production, installation, and servicing of MRI systems.
