Standard Helmholtz Coils
-
Helmholtz Coils are ideal for the measurement of Rare Earth (Samarium Cobalt, Neodymium) and Hard Ferrite permanent magnet materials (materials which exhibit a relative straight line demagnetization). Our standard Helmholtz Coils are for use with fluxmeters. The Helmholtz Coil measures the magnet sample as a single magnetic moment provided that the longest dimension of the magnet sample is less than one-third (1/3) the diameter of the coil system. By definition, the magnetic moment per unit volume is the intrinsic magnetization of the sample. With our calibrated Helmholtz Coil and Integrated Fluxmeter – and given the volume of the permanent magnet sample – the intrinsic open circuit operating B (Bdi) can be measured.

PXIe Frequency Reference: 10 MHz And 100 MHz
M9300A
Signal Generator
The M9300A PXIe frequency reference is a PXIe-compatible, compact, modular instrument that can be used with the Keysight M9301A synthesizer, M9310A source output, and M9311A modulator to create the world’s fastest vector signal generator, the M9381A. Create a CW source, the M9380A, by combining the M9300A with the M9301A and M9310A or use it as the 10-MHz or 100-MHz reference with other PXI solutions. Control the instrument through a soft front panel and programmatic interfaces tuned to your application development environment of choice.
