Magnetic Field Camera: mapping for MRI applications
MFC2046
MRI and NMR spectroscopy applications require a highly uniform magnetic field, within at most a few ppm. NMR is the only magnetic measurement technique capable of providing a field map with that degree of precision. Introduced 25 years ago, Metrolab’s NMR Magnetic Field Cameras have revolutionized field mapping for MRI magnets. They reduced acquisition times from hours to minutes, positioning errors to fractions of a millimeter, and they rendered human and drift errors negligible. Now, meet the latest generation NMR Magnetic Field Camera, the MFC2046! Map any magnet with the New generation of MFC probe arrays. Magnetometer Teslameter Gaussmeter

Transistor Testing
Radiant is introducing an I2C digital-to-analog converter product that can be attached to the Precision Premier II and is controlled from Vision. The addition of this extra voltage source makes it possible for the Premier II to measure the performance of thin-ferroelectric-film gate transistors (TFFTs and MFSFETs). This document explains the theory for such testing and gives examples of such tests using Radiant's SFRAM transistors as examples.

Shielding Effectiveness/ Conductivity Test
EM-2107A | 30 MHz – 1.5 GHz
The EM-2107A is a standard test fixture for evaluation of the electromagnetic shielding effectiveness of planar material. The fixture is an enlarged section of coaxial transmission line and complies fully with the requirements of ASTM test method D4935-1. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred. The EM-2107A is provided with a reference standard test specimen, a dynamic range specimen. Dynamic range of greater than 80dB is achievable, although the cables and other test system components usually establishes the limiting factors.
