MATS-3120SA/1M Hysteresisgraph
MATS-3120SA/1M Hysteresisgraph can automatically measure the AC magnetic parameters of Fe-Si-Al, Fe-Al, soft ferrite, permalloy, amorphous/nanocrystalline and silicon steel under the frequency of 10Hz~1MHz (continuous frequency), the measured parameters are: Ps, Bm, Hm, Ss, μa and Hc, and can calculate μ′, μ″, μL, μR, Q and AL under certain conditions.
 
The test system adopts digital signal processing and synthesis technology, it is composed of the high-speed broadband bipolar power amplifier, high precision broadband power analyzer and the industrial computer. The operation interface adopts MATS V7.0 --SMTest measurement software, which can realize the measurement of complex magnetic properties and the management of data.
