1. [RFI] A fun and educational RFI toy. (score: 1): Author: "KD7JYK DM09" <kd7jyk@earthlink.net>; Date: Wed, 29 Feb 2012 12:33:01 -0800; I picked up a LISN, Line Impedance Stabilization Network box from a fellow many years ago. This box allows me to apply power to a device under test and monitor any noise the device produces on the po; /archives//html/RFI/2012-02/msg00044.html (10,162 bytes)
2. Re: [RFI] A fun and educational RFI toy. (score: 1): Author: Larry Benko <xxw0qe@comcast.net>; Date: Wed, 29 Feb 2012 13:49:30 -0700; Be careful with LISNs and preamps. Turning on and off the DUT (device under test) will create significant transients to the receiver. I have never hurt a receiver or spectrum analyzer but have killed; /archives//html/RFI/2012-02/msg00045.html (11,548 bytes)
