Emissions quick test

Hi all, Does anyone know of a down- and- dirty , inexpensive method or equipment for sniffing out emissions issues? I've used a Spectrum Analyzer in the past with a series of different probes, but that tends to be costly. Also, Is there a universal probe kit out there? Thank you in advance.

I guess 5x12GHz I was told a few years ago the highest existing frequency in the equipment/system You better buy a new analyser which covers up to 60Gig... :-) Best regards Amund, Oslo/Norway -Opprinnelig melding- Fra: owner-emc-p...@majordomo.ieee.org

RE: EN 55022:1998 vs. ANSI C63.4

Hi Steven The function of the ferrites to prevent noise to enter the site is just one side of the story. One equally important aspect is presenting a fixed Common Mode impedance (150 Ohm approx)to the interference current sources that drive the cables and to create a fixed radiating cable

RE: Radiated Emissions setup

A few loose comments and additions on your approach: The CISPR committee is like you seeking for repeatability in test set ups. Therefore an effort is made to create a common set up for immunity and emission test set up. The idea is a (vert) cylindric volume of 1m60 miniumum diameter for left

RE: Question on highest frequency used

I would guess the answer is b) 5x the 12GHz transmitter. I think (going from memory) ANSI C63.4 gives test instructions for receivers. The Local Oscillator or the receiver must be active, i.e. receiving a real signal (alternately you can inject a test signal into the receiver). Thus making

RE: Radiated Emissions setup

Neil, I would like to see the pictures of your audit board. Without seeing the pictures I have the following comments. 1. I think this is a very good idea from a repeatability standpoint and I would like to consider adopting it. 2. It may be more trouble than simply draping the cables over the

Re: EN 55022:1998 vs. ANSI C63.4

The idea of putting the ferrites on the cables is to prevent noise from outside the test site form entering the test site. My opinion is that you should not have to repeat the test as the ferrites do not have any effect on what is happening in the room where the test is being performed. Just

Question on highest frequency used

Hi - and just when I thought I had it all figured out.. I have a question on the FCC requirement to test a product to the highest frequency used. Say a company has an RF receiver that has a DSP processor in it running at 50MHz. Lets also say that said receiver is pointed at a transmitter that

Re: Grounding in an operating room environment ...

Doug, You are really asking if the product is Type B (earthed applied part) or Type BF (isolated ground part) according the the classification of IEC 60601-1. The answer is that some types of medical equipment must be Type BF or even Type CF (direct cardiac contact) according to the

EN 55022:1998 vs. ANSI C63.4

Probably won't get many responses this week as everyone with a travel budget is now in Minnesota. However, I'll try it anyway. In the 1998 version of EN 55022, radiated emissions tests on table top products are performed with a ferrite tube or clamp on each cable that exits the test site (i.e.
