MSN12 hand-held power line EMI 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. MSN12 can measure electromagnetic interference (EMI) between any connections in a power outlet.  It also allows measurements of EMI between different grounded parts without creating ground loops using any oscilloscope or a spectrum analyzer, grounded via power outlet or not.

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

A newer version of this adapter is MSN15 which has much wider bandwidth.  If your applications are limited to EMI in electrical outlets you may want to look at MSN17 EMI Adapter.
