In one of my previous lives, I was EMC Engineer/Lab Manager at a commercial
EMC Compliance lab. We had the following process for report generation:
1) The time charged for report generation was 3 hours, and I did not see any
customer complaining.
2) The package generated for Class-B systems to be forwarded to FCC for
approval was charged at 6 hours, which included report, additional information
needed, and EUT pictures etc.
3) The report was written after the test was completed and the EUT passed the
test. Report for a failing EUT was prepared only if the customer asked for
it. Otherwise, only the raw test data was provided to the customer. Also, no
report was generated for the pre-compliance scans.
4) The preferred software for report generation was MS Word (DOS version).
The EUT information was gathered by the test engineer and provided to the
person writing the report. Report writing consisted mainly of replacing the
EUT/customer specific information within the template.
5) Every report was reviewed by another person before it was provided to the
customer.
As far as I know, the system worked quite well.

EMC Test report generation
Hi all
just wondering what time is considered realistically to generate a test
report for a commercial product, meaning no Mil or similar. Since most
customers will not accept a huge price tag for the report, management
usually calculates less time then needed for an average test report.
Also what is a time the customer is willing to wait for the report after
the test was completed?
What are the tools to generate a report? I assume the most common tools are
Word. Also have seen Lotus Notes based for intra company use and data base
driven reports (in-house only)
Next question, how to generate a report
Have seen automatic templates, Single files for each item, reports copied
again and again and just some EUT details changed ( Sometime even
accidentally two EUT are listed in the report), single sheet collections.
When is the best time to write a test report?
Basically I consider the best time to write most of the report is prior to
testing. Meaning, before the test starts, the data of the EUT including
configuration, options cables accessories and a schematic showing the
interconnections of the EUT and accessories are provided by the customer in
a format, easily to be integrated into the test report.
During the test the data from the measurement software, mostly anyway EMI
can be integrated by a macro in the test report. The couple lines of
additional comments, if the EUT fails can be written during the test.
Pictures go direct from the digital camera to the computer HD and from there
to the report.
However, real life is a different animal. Mostly little data before testing
about the EUT configuration, Measurement data by copy and paste, and most
notes let's say handwritten. And then sometimes later the report will be
written.
