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.

Greetings:

I have been looking for a HP Signal Analyzer for compliance testing.
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.
