Some times when you are up to get full understanding of harmonic content and of digital power meter (analyzers) product specifications, you need to use pencil and paper, or alternatively, Microsoft Excel and Adobe Photoshop. :)

Digital power meter (analyzers) for AC only they come at different bandwidth this starting from 45Hz and up to a higher number.
Digital power meter (analyzers) for AC & DC they come at bandwidth this starting from 0Hz up to 100kHz (the recent developed ones).

Either way, freshest documentation from EEC which I did succeed to find for free, this mentioning as obligatory harmonic content analysis (measurement) up to 13nth of Odd harmonic for Class A equipment.
13nth of Odd harmonic this is at 650 Hz

Next time that you will review digital power meter (analyzers) product specifications, you better compare it bandwidth with this chart that I made for our ITTSB Blog visitors.
This gives an instant clue of harmonic order quantities  that its product were designed to offer for you to review.

High number of harmonic order quantities does not translate to accurate measurement of its one order, and therefore sum of product specifications this should be studied in depth.

This is an interesting keeper chart :)
Because this is useful also for all multimeter & clamp meter buyers, so them correctly evaluates bandwidth potentials of its one tool.
