X26 is 19Hz, and thus is not 100us

Taser International and their brain-trust minions make much of the short duration of the X26 waveform. They constantly claim in various articles and propaganda pieces that each taser pulse is only 100 micro-seconds in duration.




First of all, with a 'main phase' time of at least 100 micro-seconds and a subsequent decay time-constant of 48 micro-seconds, the entire pulse is in reality much longer than 100 micro-seconds (to drop to very low values). 100 micro-seconds is just the 'main phase'. This is really just a clarification for those that might otherwise be misled.

But far more importantly, these guys appear to be ignoring the fact that the duty cycle of the 19Hz and harmonic spectral components is 100% continuous duty cycle for the entire 5 second deployment cycle (or 31 seconds, or even 2 minutes and 49 seconds, or however long the trigger is squeezed).

Refering to the above waveform graphic, note that the DC pulse part of the waveform (outlined with a thin green line at the start and tailing off to the extreme right) contains far more area than the relatively short 100 kHz oscillating arc phase. Although the monophasic pulse isn't as tall in peak amps, the long and low monophasic pulse covers a lot of area. And it's 19Hz. And it lasts for 5 seconds.

And they do admit that the X26 is "19Hz". See the graphic from the Kroll puff-piece (below, and see [LINK]). They place the X26 dot at the 19 Hz point on the graphic (and the stupid dot is a hopeless over-simplification of a complex spectrum [LINK]).



But they fail to connect this dot to the resultant 5s duration. Even though it is duh-obvious.

The duration of these more-dangerous low frequency spectral components is not 100 micro-seconds.

They're FIVE SECONDS duration.

Or more.

Or even much more.


This basic fact casts a serious doubt on their claims of safety based on the very short 100 micro-second pulses.

Their arguments might apply to the older M26 taser where the output waveform didn't include the nasty monophasic DC offset pulse. But the X26 taser does include that monophasic DC offset pulse, and thus the energy in that part of the waveform is 19Hz [LINK]. As indicated on the Kroll graphic above.

And thus... the actual duration of the X26 output is at least 50,000 times longer than they claim [LINK].

5,000,000 microseconds, not 100.

Is anyone out there searching for some missing 'orders of magnitude'?
