Sushil, You bring up an interesting point. We use an 8593EM EMC Analyzer for all of our emissions testing. We have been able to do most of our Class A verification work with this unit, since the EMC Directive is Self-Certification, and the FCC tells me that they will not enforce the Cispr 16-1 compliant receiver requirements for Verification testing. However, I have been unsuccessful in getting any Competent Bodies or the FCC to accept data taken on my non-compliant receiver. This means that all of my Class B testing must be farmed out to test labs who use the appropriate equipment. It is clear that this situation is not cost-effective, and extends my time to market. Because of this issue, we are in the process of gearing up to purchase an 8546A, so that can regester our site for FCC, VCCI, and all other Qualification testing.
Although I would have to say that I get excellent correlation when comparing data from my receiver to data from the local test lab, the fact that the thing isn't CISPR compliant has been a major roadblock from day one. I cannot regester my site with the FCC, or get NVLAP approval. Because of this, I would recommend spending the money on a compliant receiver. For a low cost alternative, you might consider the HP 8568B. This is a low cost, older model, that you can pick up for about 20K with the Quasi Peak adapter. These are high-quality, accurate units, and while they lack some of the the features of the newer models, they are used by a majority of the test labs, and are supported by most EMC measurement software. With the Quasi-Peak adapter, they are completely CISPR 16-1 compliant. I hope this perspective helps out.

The HP 8590 series is only a pre-compliance (non CISPR-16 compliant) tool, yet it is being used in the industry widely for compliance testing. Can somebody explain to me why I need to buy the 8542E or 8546A ($60K+) fully CISPR-16 compliant receivers, when a pre-compliance analyzer seems to be the industry standard.
