RE: Agilent 6842A
Then you haven't dealt with agilent (no caps on purpose) lately. Ask them if they can spell the other company's name. I have been through similar hoops as of late, and they couldn't spell RS.

As a loyal HP/Agilent customer, I would expect them to take care of this issue. This is why we buy certain brands of test equipment, and not others. I feel that we got ripped on this deal since the 6842A is not a cheap piece of test equipment. Tim Pierce

RE: Radiated Immunity
Identify the source of propagation for these frequencies and their egress path. If you can successfully lower the radiated emissions level from these you should have a subsequent decrease in your susceptibility. If you are having a problem at 3V/m, the radiated emissions should be fairly strong. A caveat to this would be aware of ingress paths to enclosed areas whose dimensions may form a resonant chamber for the frequency of concern. Hope this helps. JOHN E.

RE: Evaluation Boards
I had forwarded this to Vic upon receiving his request last week, but viewing some on the responses that I have seen, I feel it would be appropriate to put it out for general viewing. Look at 47 CFR § 2.803 Marketing of radio frequency devices prior to equipment authorization. (a) Except as provided elsewhere in this section, no person shall sell or lease, or offer for sale or lease (including advertising for sale or lease), or import, ship, or distribute for the purpose of selling or leasing or offering for sale or lease, any radio frequency device unless: (1) In the case of a device subject to certification, such device has been authorized by the Commission in accordance with the rules in this chapter and is properly identified and labeled as required by § 2.925 and other relevant sections in this chapter; or (2) In the case of a device that is not required to have a grant of equipment authorization issued by the Commission, but which must comply with the specified technical standards prior to use, such device also complies with all applicable administrative (including verification of the equipment or authorization under a Declaration of Conformity, where required), technical, labeling and identification requirements specified in this chapter. (b) The provisions of paragraph (a) of this section do not prohibit conditional sales contracts between manufacturers and wholesalers or retailers where de-livery is contingent upon compliance with the applicable equipment authorization and technical requirements, nor do they prohibit agreements between such parties to produce new products, manufactured in accordance with designated specifications. (c) Notwithstanding the provisions of paragraphs (a), (b), (d) and (f) of this section, a radio frequency device may be advertised or displayed, e.g., at a trade show or exhibition, prior to equipment authorization or, for devices not subject to the equipment authorization requirements, prior to a determination of compliance with the applicable technical requirements provided that the advertising contains, and the display is accompanied by, a conspicuous notice worded as follows: This device has not been authorized as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained. (1) If the product being displayed is a prototype of a product that has been properly authorized and the prototype, itself, is not authorized due to differences between the prototype and the authorized product, the following disclaimer notice may be used in lieu of the notice stated in paragraph (c) introductory text of this section: Prototype. Not for sale. (2) Except as provided elsewhere in this chapter, devices displayed under the provisions of paragraphs (c) introductory text, and (c)(1) of this section may not be activated or operated.

Article was also published by AP in today's Boston Globe. The following excerpt is from the site you noted Regards, Paul J. Smith Teradyne, Boston Chip maker will replace motherboards using its 820 chip set due to noise caused by simultaneous switching of signals. Intel Corp. has acknowledged another setback for PCs using its 820 chip set. The company announced Wednesday morning that it will replace motherboards using its 820 chip set that are exhibiting symptoms of a problem with a related component -- called a memory translator hub, or MTH -- with synchronous dynamic RAM (SDRAM). While the hub is not part of the 820 itself, it is required on a motherboard that uses SDRAM. It enables the chip set, which was designed to work with Rambus dynamic RAM (RDRAM), to use less expensive, more readily available SDRAM. We have found that some systems ... may be sensitive to system board noise, an Intel spokesman said. Hangs and reboots The MTH problem, which manifests itself by system hangs and intermittent system reboots, is due to noise caused by simultaneous switching of signals on the MTH buses, Intel officials said. Intel is working with PC and motherboard makers to notify computer users of the problem and to offer a replacement motherboard. Intel plans to replace all the 820 motherboards with SDRAM support that it sold directly to customers with an Intel 820 chip set motherboard with RDRAM memory. Computer users who believe they are affected should contact their manufacturers, or they can check Intel's Web site, where they can download the MTH ID Utility to test for the presence of the hub. The MTH support site also includes additional information on the problems. We believe less than 1 million boards with the MTH have been shipped to customers, an Intel spokesman said. However, since we have determined no root cause on this issue, we have decided to offer a replacement.

RE: The wisdom behind all these standards
The question is posed; what is the wisdom behind all these standards? Indeed the are numerous standards that have been, are, and will be brought into existence effect every aspect of our various industries. The history of the beginnings of these regulates can be traced back to the events of the Titanic. As we move forward from this point we see that the number of electrical and electronics based equipment as spread from single end items, to necessary, critical, and life support interfaces and command and control devices. It is these reasons that make the control of emissions and the immunity from threats an absolute necessity. My background covers both sides of the issue, that of testing for and complying with the various standards. While involved in the first it was my goal to establish a reputation through out the industry that when my or my colleges names appeared upon a test report it was understood that all due diligence had been exercised and the data reported was accurate. In pursuit of this, there were times when a client had to be made aware of the fact that their equipment was not compliant in its present state and then embark on a course to rectify the problems. There were no maybes, or if I do this to get by then I'll fix it of the next rev. If a client chooses to tightly encroach upon a limit, it is incumbent upon the test laboratory to inform them of such and document it. Integrity and pride of workmanship have no price. Working on the other side of the equation, it is only a change in that now the knowledge has to be spread across the design teams and other parts of the company. Once again though integrity takes precedence. This leads to the answer of the first question; what is the wisdom of these standards? Standards should change by the logical data supported arguments that are presented to industry and the committees. Yes there are standards which have outlive their usefulness and there are interpretations that may need review, but it will take the objective analysis of all aspects to implement changes. Until changes take affect, the are many sources of information available and EMC specialists to provide consultation. Use these in the evaluation and design phases to develop solid methodologies that prevent system level fixes, do not impact scheduling, prevent unplanned expenditures of reworking or redesigning, and eliminates the why is compliance always a problem? Below is an excerpt of a paper that I did for one of the groups that I support: EMC testing encompasses the measurement and verification of radiated emissions (RE), conducted emissions (CE), radiated immunity (RI), conducted immunity (CI), electrostatic discharge (ESD), electrical fast transients (EFT), and power line anomalies (surges, transients, and fluctuations.) These measurements are compared to standards set forth by FCC, CE (CISPR 22, CISPR 24, EN50082-1 et al.), VCCI, and CSA to prove compliance. Compliance to these standards is mandatory to be able to sell and export electronic equipment to our customers. Compliance to standards is only the beginning. As a component manufacturer we have no control of the final end-item, its manufacturing tolerances, or final configuration when in use. For these reasons, it is imperative to have as much margin between the demonstrated emissions and the applicable limit. For the same reasons, emissions margin is not the last aspect to be considered; identifying the immunity margin is as, or more important. More important in that as of July 01, 2001 it will be mandatory to comply with four additional immunity tests. As a note, the industry is already moving toward certifying to these standards. The question now would be; how does the quantification of margin help us? The quantification of margins provides us with a demonstrable measure of the effect our product will have on the performance of an OEM's end item. The OEM has the greater task of certifying a product; their situation being, they are integrating a system that must meet the same compliance standards. From the system level view two things become concerns, 1) how do the emissions profiles of all components align (thusly contributing to the overall emission profile of the system) and 2) what component is the most susceptible to interference. The astute OEM's engineers will evaluate the components from which the system is to be assembled, scrutinizing them for performance and their compliance documents. It is at this point, performance being similar, that documented margin in the emission limits and testing above the required immunity standards can make the difference in our products being selected. Discounting the selection process of an OEM, ascertaining the margins and thresholds of susceptibility, provides us with recourse should a question arise. With data in hand we can establish that we have met and exceeded the base requirements for the market we are selling to and have only to question the quality
