waveform - picture request BX1500G

[Anonymous user]

I would like to see an actual Oscilloscope output waveform picture of the Stepped approximation to a sinewave. If possible from the specific UPS that I am using.

Can someone from APC technical support please post a picture of the output at load for this model?
I tried to call technical support, but they told me to Google it, yeah ok that didn't work for my model.
I got general information about how it would work, but not how specifically my unit works.
If you would like to make more customers happy, how about posting this data directly on the technical specifications page in which the product appears? This would be especially nice on the "pure" sine wave versions as well so we can see what that's supposed to look like, instead of what the stepped looks like.
Yes I know what a ideal sine wave looks like, and that grid power doesn't always look that great, but compared to a square wave at least my PC doesn't power off when the power does. No I haven't had any trouble yet, but the tech in me wants to know and the penny pincher wants to get something good enough, but not bad. I figure if this UPS is sold with the "intention" of being used on a PC then it should work on my PC, otherwise they should not sell anything but Pure Sine wave UPSs if they are intended for PC use.

Thanks for the waveforms Impedance. I see that for the most part it's a pure square wave not really stepped that much at all, it would have been nice if there was one more step in the sequence, but I guess that's what makes them less expensive, oh and yes I will be getting a pure sine wave version next, it's just a shame though that I can't just pick one up at my local Best Buy, they really shouldn't sell anything but pure sine wave any more with all the new power supplies running active PFCs.

Unfortunately we do not have documentation depicting the actual sine wave shape of the UPS. If you would like to research about it the wave form is called Step Approximated or Quasi Sine Wave. Hope this helps.

OK so APC doesn't document the waveforms, but does someone else have this model (or generation model) and a oscilloscope, that would be willing to post a picture of the waveform under load (half power is fine, but full power is desirable)
Note to APC, for the future, could you consider documenting this for your tech minded customers please!
