RE: Ivory Coast ITE Compliance Requirements
Hello Collins, Meeting the IEC standards applicable to your product should get you into the Ivory Coast. To be sure, get ARSO (Africa Regional Organization for Standardization) approval. You would probably need to get approval thru an NSB (National Standards Body) of a member country (The Ivory Coast is not one). Testing is based on the IEC standards. The mark itself consists of three circles (inner and outer) with the Africa map in the middle. It is usually affixed to the product with the mark of the approving NSB. There is a Quality System to ISO9000 and surveillance program required. The ARSO page is at: http://www.arso-oran.org/English/Main_menu.htm Regards, Bandele Jetstream Communications, Inc. badep...@jetstream.com -Original Message- From: Collins, Jeffrey [mailto:jcoll...@ciena.com] Sent: Wednesday, December 05, 2001 11:01 PM To: 'emc-p...@majordomo.ieee.org' Subject: Ivory Coast ITE Compliance Requirements Group, Anyone familiar with Compliance requirements to deploy ITE into the Ivory Coast?

RE: Stepping receiver, step sizes.
Ken and I have been talking this over off-line, and it seems like an important thing to note is that the HP / Agilent spectrum analyzers tune over a measurement range by continuously sweeping their local oscillator. Setting a resolution bandwidth and a span width does not mean that the analyzer will tune in discreet hops. Even under external HP software control, the analyzer firmware still does (perhaps a series of) analog sweeps. OTOH, if you use your own software, specify a resolution bandwidth, and then send a series of tune, measure, tune,... commands, then you can miss emissions between the skirts of the passbands if your step size is too large. You have to understand how your receiver or analyzer actually covers a frequency range.

RE: Stepping receiver, step sizes.
Hello Ed, With the signal @2955 MHz (CF2950MHz)I get similar results. In all Spans I get approximately 65 dBuV which is 10 to 20 dB above noise floor. Regards, Ken Hall -Original Message- From: Price, Ed [mailto:ed.pr...@cubic.com] Sent: Friday, December 07, 2001 10:25 AM To: 'HALL,KEN (HP-Roseville,ex1)'; 'John Woodgate'; emc-p...@majordomo.ieee.org Subject: RE: Stepping receiver, step sizes. Ken: Did you do your test by first setting the receiver to the 2950 MHz signal, and then setting up a symmetrical scan from that reference? For example, if I used a spectrum analyzer to look at 2950 MHz, by setting the CENTER FREQUENCY, and then selected a FREQUENCY SPAN of 4000 MHz with a RESOLUTION BANDWIDTH of 10 MHz, the SA would start its scan at 950 MHz and end at 4950 MHz. The 2950 MHz would be the mid-point sample frequency. Regardless of what SPAN and BANDWIDTH I might choose, the mid-point will always stay the same and always be measured. 100 % probability. Try setting the signal generator to 2955 MHz. Then scan from 2900 MHz to 3000 MHz, using a resolution bandwidth of 1 MHz. BTW, my 8571A system uses an 8566B SA, and that analyzer actually uses an analog swept oscillator. But under software control, it will obey the software requests to look only at the directed frequency with a view of only the selected resolution bandwidth. In the above example, it would see 2949.5 MHz to 2950.5 MHz (3 dB down points), then next see 2959.5 MHz to 2960.5 MHz. Signals between 2950.5 MHz and 2959.5 MHz would be seen anywhere from 3 dB too low to completely missed in the SA noise.
