Компания Schwarzbeck Mess-Elektronik - немецкая фирма, разрабатывающая и производящая продукцию для измерений и испытаний на ЭМС (электромагнитную совместимость). Компания была основана в 1953 году в Германии Гюнтером Шварцбеком, который во всей Европе считается основоположником по созданию приборов для ЭМС-измерений. Головной офис Schwarzbeck Mess-Elektronik расположен в городе Шёнау-им-Шварцвальд.
Компания Schwarzbeck Mess-Elektronik выпускает широкий ряд измерительных антенн с сопутствующими аксессуарами, эквиваленты сети, системы… подробнее
The magnetic, handheld coil FESP 5139 was designed to generate defined magnetic fieldstrength in the frequency range from DC up to 5 (7) MHz. The main application is immunity testing against magnetic fields according to IEC 61000-4-39.
Depending on the current source characteristics magnetic fields up to 360 A/m can be generated for a short time. The generated magnetic fieldstrength is pro-portional to the coil current. A distance ring allows a precise spacing of 50 mm between coil and EUT surface. Other distance rings can be used to scale the current-fieldstrength ratio. The highest fieldstrength levels can be achieved using the shortest ring. There are further rings available on request in order to provide a certain scaling between coil current and magnetic fieldstrength (e.g. 1 A coil current = 20 A/m fieldstrength).
Application as Sensor for Magnetic Fields:
The FESP 5139 can also be used to measure existing magnetic fields. For this purpose the FESP 5139 is connected to a frequency selective 50 Ohm measuring instrument e.g. a spectrum analyzer or a measuring receiver.
