Brian, Here is my two cents worth: RF energy generated by Group 1 is intentionally only for internal function. And Group 2 intentionally generates RF for their working objects.
Thus an electronic microscope (which is not a "smaller bench type test equipment" -- see your Email) falls under Group 1. On the other hand, microwave oven and RF medical therapy belong to Group 2. Please correct me if I'm confused. Barry Ma Anritsu Co.

The standards give some examples of product types but there should be a base criteria which was used. Group 1 products seem to be smaller bench type test equipment like signal generators, spectrum analyzers, and such. Group 2 seems to be products that generate a spark or uses RF in some way to heat, melt, or spark erode. The gap between these two groups seem to be wide which leaves a very large gray area. Is there a defined criteria that exists? Please feel free to give me your thoughts so we can draw up our own criteria if necessary. Thank you in advance, Brain Kunde Compliance Testing Center LECO Corp. --------- This message is coming from the emc-pstc discussion list.
