analyzer on the market utilizes resistors that are rated at 5% tolerance (DC) with a power dissipation rating of only
175 watts. These are just a few of the subtle differences between the new BC Biomedical ESU-2000 Series of
ESU analyzers and competitive analyzers on the market today. Don’t let the perceived “promise” of a particular
brand fool you into making an inferior choice when it comes to selecting your new ESU analyzer, Do your
homework before you purchase!
Those Crazy & Exotic Pulsed Waveforms
Conmed and Erbe are two manufacturers that offer electrosurgical generators with pulsed waveforms. Typically,
these pulsed waveforms have long single cycle time periods within which a signal is pulsed for a brief period of
time. This results in a very low duty cycle waveform that is extremely difficult to measure, let alone measure
accurately.

The BC Biomedical ESU-2050 Analyzer handles these pulsed waveforms easily, and yields accurate results time
after time, leaving all competitive units behind, wondering what hit them.
