BX1500G versus BX1500M

[Anonymous user]

Last week I bought the BX1500G from a local retailer.  It's a quality product and thus far it works well.  After the purchase I found out that APC has discontinued the BX1500G and replaced it by the BX1500M.  My only question and concern: What is the real output waveform of the newer BX1500M as shown on an oscilloscope and spectrum analyzer?  I realize, in advance, that both of the UPSs are a simulated sine wave output.  I just wonder whether or not the real output waveform of the BX1500M is any different from the output waveform of the BX1500G.

Thank you,

Mark
