Conducted Emissions, average method
Ladies and Gents, Since the original posting, would anyone concur with the spectrum analyzer settings and steps necessary to successful complete conducted emissions using the average method: Please consider using this eight (8) step procedure as a generic model for your suggestions. A1) Set the Video Bandwidth on the analyzer to one tenth the resolution bandwidth. A2) Center the signal frequency in question on the analyzer screen. A3) While keeping the chosen signal in the center of the analyzer screen, reduce the frequency span to 0 Hz. A4) Reduce the video bandwidth on the analyzer until there is no modulation on the signal in question. Typically, this would occur when a smooth trace is displayed on the spectrum analyzer. A5) Set the analyzer to linear mode, depress LIN button. In linear mode it may be necessary to increase the sensitivity of the analyzer by pressing the Reference Level UP or DOWN arrow key. A6) The signal level should be above the lowest graticule and below the highest graticule on the analyzer screen. The analyzer at this time will be in uv. It will be necessary to press the SHIFT and then C buttons in order to be recording under dBuV. A7) Depress the MAX-HOLD button, and PEAK SEARCH button, now record this meter reading on the Excel spreadsheet project file. A8) Return the analyzer to the normal operating mode. NOTE: It is important to remember when reducing the video bandwidth, resolution bandwidth, or frequency span as to not cause the analyzer to become uncalibrated, nor to cause the identified peak signal to be lost.

How to Upgrade an HP8566A
Hello folks, Anyone familiar with an upgrade service or consultant who can convert an HP8566A to an HP8566B??? In terms of commercial EMI testing, would this be a good, reliable inexpensive alternative compared to using an original HP factory built 8566B or newer HP spec analyzer / receiver model??? A few months back, I heard there was a contact in the San Diego, CA area. Any names or numbers heard of preferrably in the Southern California Area?

RE: How to Upgrade an HP8566A
Steve I know that we have upgraded at least several HP8566A's to B's. I believe we did this by returning them to HP to perform the upgrade service. I would recommend contacting your local HP rep directly. Or, try their Test Measurement call center at 800-542-4844.

RE:cellular phone supply system
Moshe, I have been testing power supplies for use in cell sites to EN 60950 (ITE equipment). This standard has been requested and accepted by the company purchasing these supplies from the power supply vendor I am dealing with. UL has been testing the supplies to UL 1950.
