Until now i have recorded pulse width and i have to scroll over screens to catch a glitch or abrupt changes in pulse width with my fluke 123B scope. If you select pulse frequency or duty cycle, you are able to track numbers at very low speed rate (maybe I don´t know enough this tool).
Anyway, in near future i am going to get one of those picos, not only for their navigation features, but for its known good waveforms database.
Yes. Picoscope will graph frequency, Duty cycle, and more.
"Knowledge is a weapon. Arm yourself, well, before going to do battle."
"Understanding a question is half an answer." I have learned more by being wrong, than I have by being right.
Duty and Frequency are both available as math channels. So you get both the raw signal trace and the duty and/or frequency trace on the screen at the same time.
Download the software and have a poke around in demo mode.
As shown in the video above, the only limit to PicoScope's advanced math channels are your imagination and an equation that the program allows.
There is also a number of threads on Pico Technology's site (under the automotive section>Library>Training) labeled Maths is Cool. So far there are 16 entries but they are all full of amazing information.
Wahooo... once more I take my hat off as compliment to your suggestion to look at the Math application at the Pico library.
I have been looking for precisely these type of detail and concrete application for the Auto trade.
Also, just browsing at one of the CTI Virtual training Videos I realized that I think I had a miss opportunity with that 4Runner that I had to let it go.
Could it be a reasonable test checking the Frequency on the math channel for the distributor signals?
It was purchased by one young BENZ tech in my area; and his father apparently is a seasoned tech at the same dealership. They have had no time to work on it but promised to share what they find.
Thanks, most probably many other people will benefit from your post.
