The TI LMX2594 wideband PLLatinum RF synthesizer, available from Mouser Electronics, is a high-performance wideband phased-locked loop (PLL) RF synthesizer with an integrated voltage-controlled oscillator (VCO) that can generate any frequency from 10 MHz to 15 GHz without using an internal frequency doubler, eliminating the need for complex onboard filters to remove subharmonics.
The requirements for current harmonics, subharmonics, and interharmonics specify the allowable distortion as a function of multiples of the fundamental frequency of the input voltage.
Additional requirement is that the stimulating frequencies cannot be harmonics or subharmonics from each other [19].
From the frequency spectrums of all the UPSs it is clear that outputs of all the uninterruptible power supplies contains subharmonics, harmonics and Interharmonics.

The VSA-1215 allows the user to go down to 1 Hz and even below that, if he needs to, so he can actually see what's happening at low frequencies Co especially subharmonics on machines with operating speeds from 1,800 RPM to below 600 RPM.
