Brian & Ed: You've nailed it. There wasn't a valid cal sticker, so I verified the performance. The waveform looks out-of-spec. Rather than call places and ask them to 'fix it', I wanted them to evaluate it on their own. Surge voltage might be corrected by a simple pot adjustment. I don't want to think about what it would take for pulse width correction. I had to get another brand of surge generator repaired a few years ago -- what a pain!
Since we're not an accredited test house, I'm really just interested in the waveform meeting the standard. I'll contact the 'no bid' houses and clarify what I want.
