China tach doesnt work
Thanks! I got the specs all wrong off memory as I wrote this at work. Its actually a 100MHz (200MHz firmware update) Hantek DSO5102 with 1GSa/s sampling and 200MHz 1-10X probes.
.
This Hantek has an 'auto set' that seems to get about any wave form to show up on screen in a decent spread out waveform. My probes are 1x-10x switcheable and were on 1x during testing. I didnt realize this when setting it up outside. And I didnt think to alter the trigger level as I was kinda in a hurry to see if it would even work. How would I use the external trigger on this? I did see a waveform that looked like a huge spike with a trailing 'ring' but the frequency counter never gave me an accurate figure, it was all over the place. My other scope is a 60MHz HP 54603B using the same probes. Maybe the anolog style CRT would give me an easier waveform to analyze?
