At 8:00, the vertical ranges will probably depend on the probe attenuation. At 9:40, triggering wasn't a problem -- the pulse train was stationary; the problem was the sampling frequency beating with the pulse frequency... instead of sampling at the peak it sampled half-way down on each side during some traces.

There's also noise and possibly some quantization error at that scale (200mV)

I'm astounded at the value! that much performance for $25 is really good. Even with a 200kHz analogue bandwidth (which I'm sure is limited by an input filter that could be 'adjusted'😂, it's really great for situations you mention. Heck, you could even use it to explain aliasing and digital down-conversion with a 455KHz IF AM radio. How to use a scope and how to interpret the waveform is 80% of mastery. I'd pay an extra $5 for a trigger input that doubled as a 1-ch logic analyzer. Really cool!

@surferdudemi Жыл бұрын

Bandwidth is likely limited by the internal A/D sample rate, so while you might be able to "adjust" the input filter, you would not gain much in terms of performance.

@surferdudemi Жыл бұрын

At 9:20, it appears the problem with the sync pulse triggering is not the scope: it's either that the amplitude of the pulse varies, or (at 200mV / div) you're getting quantization error on the signal. That would make it appear to shift slightly. There also appears to be a little noise in the signal which could make it appear to shift.

@koenlefever Жыл бұрын

9:02 When you started talking about a "sync pulse" before zooming in, and I just saw the spikes, I assumed for a moment you were talking about some synchronization pulse. Then you zoomed in and I recognized the function as a "sinus cardinalis" sinc(x)=sin(πx)/πx, and I understood you were talking about a "sinc pulse" rather than a "sync pulse". BTW, according to the cc subtitles you talk about a "sink pulse", which briefly added to the confusion.

Hi , I am knew to electronics. I replaced an alcohol addiction with electronics. At first I didn’t know how to use a breadboard, now I have built a MOT self starting Jacobs ladder and some Slayer Exciter Circuits. I just ordered a mini oscilloscope and it should get in in a week or so. I want to build a pulse laser driver to run a 905nm 75w laser diode that has a typical voltage of 12.8v 30a 100ns max pulse 0.1% Any idea’s of a simple cheap way to drive the laser diode ? The arduino is too slow, so I found I can generate a 100ns PWM with a 555 timer but I don’t know what MOSFET to use for the 100ns switch and if I need a capacitor or what size and if I need an inductor ? Any thoughts ?
