VIA Bravo MRI™ & MRI II™ Network Analyzers For Testing MRI Coils 0.1 - 3.0T PC Vision Smith Chart Specifications • Frequency/Tesla Range: • Tuning Resolution: • Measurement Speed: • Freq. Display Width: • Impedance Range: • Impedance Scales: • Phase Angle Scales: • Harmonic & Spurious: • Output Power: • Power Requirements: • Input Connectors: • Display: • Non Volatile Memory: • • Dimensions: • Weight: The VIA Bravo MRI & MRI II are Network Analyzers that accurately measure impedances from 2 to 2000 Ohms, resistance, phase angle, X, Q, return loss, and SWR. Both Bravos can simultaneously provide graphical display for any two measurement parameters. The frequency sweep is plotted in the X axis and independent left and right Y axis scales are user selectable. The Bravo’s portability and ability to function in close proximity to magnetic fields make it the ideal test instrument for installing and servicing MRI systems. Additionally, our Bravo products come with Bravo PC Vision™ software. This software permits remote control operation of the Bravo MRI or MRI II to upload test results to a PC or laptop, view the VIA or Smith Charts in full color, store and print complete analyzer documentation. While the Bravo’s LCD can support displaying two parameters, PC Vision can display one or all the testing parameters at once. The Bravo MRI or MRI II will save time, reduce capital expenditures, and reduce costs typically associated with the installation and servicing of MRI Systems.
