Will I need this only when testing primary ignition and injectors?
As Jamey stated, the Picogroup section is where we provide Picoscope assistance.
Just a suggestion for all you Picogroup members... You all have access to the Picogroup boards on the forums. If you really want the best assistance from other members, post there. The public areas of the boards have a wider audience, but you will not get the same level of assistance there. What section you post to depends on what you want from your thread. If you want to share something with the world, post in the public areas. If you want help with something, especially PicoScope assistance, post in the Picogroup areas. PicoScope assistance is not provided in the public boards.
The attenuator question is an important one and Jamey covered that too. In your case, the 4425 has a 200V input maximum. So, coil primaries are going to be the main thing that is going to exceed that. If you have doubts about the voltage, use an attenuator. You can always take it off.
That being said, the 4425 is the toughest scope Pico has released to date. We actually tried to destroy a prototype unit here doing all kinds of things to it that should never be done. We were unsuccessful.

Welcome Mark. I am glad you were able to sift out the BS in that other discussion. So, now take a drink.

Also be sure to read the important topics on this board to help you get started here with the forums:
