How much EMI is on your power lines? Are you working with power line communication (PLC)? How to assess the levels of noise and its properties when it is obviously a bad idea to connect your oscilloscope or a spectrum analyzer directly to your power line? Our EMI power adapters will help you with that.
OnFILTER's EMI interface adapters provide galvanic separation from high mains' voltages but a straight path for high-frequency signals so that you can connect your sensitive instrument to live power lines for analysis and quantification. We offer plug-in and hand-held adapters which can measure both differential ("normal") and common-mode noise. Among applications for EMI Adapters are:
Conducted emission measurements
Compliance with SEMI E176 Standard and IPC-A-610 EOS section
EMI audits, diagnostics and troubleshooting

EMI Adapters enable measurements of power line communication (PLC) which is a part of Smart Power, including the following standards (depending on model):
Homeplug AV and AV2 -- G.hn Wave 2 -- CENELEC EN50065 (all bands) -- IEEE 1902.2 -- ARIB (Japan) -- FCC
As a part of PLC, EMI Adapters are great tools for data security since they allow monitoring of what happens on the "back door of your computers and servers - power lines.
Our EMI adapters have true balanced input allowing for measurement of signals independently of ground loops or whether your instrument is grounded or not.
How to select the right EMI Adapter? Start with why would you need to conduct measurements. If your interest is measuring high-frequency signals only in electrical outlets, there is no need to try to fit and to hold test probes in an outlet - a plug-in model would be the best choice. If your interests are more diverse and you would like to know EMI levels on ground, in electrical panels, inside equipment, and elsewhere, a model with test leads would be more appropriate.
MSN15 and MSN17 are the newer models with extended frequency range up to 200 MHz which covers not only EMI on power lines and ground, but also majority of power line communication (PLC) standards. Both MSN15 and MSN17 are certified for IEC61010-1 (Third Edition), 2010; IEC 61010-2-031.
MSN01 and MSN12 are time-proven models with solid performance for basic EMI measurements on AC power and ground that served as a foundation for MSN15 and MSN17 design. For new applications we encourage use of MSN15 or MSN17. If you are already a user of MSN01 or MSN12 and would like to add the same model, MSN01 and MSN12 will still be available.
