If you are in the US, call me. I can answer all of your questions. 1-877-628-4899 toll free. Our pricing is competitive and we have a $350 support package included free with each kit you get from Autonerdz. We have happy users on five continents. There is a good reason for that.
You are heading in the right direction. The Automotive industry trend is toward more PC based diagnostics for many reasons. The PicoScope is the best PC based DSO for the money available. We have a couple of custom kits which differ from others'. Our Master Kit is the Pico Advanced kit but has two 20:1 attenuators included. Our Powermaster kit is the same thing but instead of the ADC 212/3 it has the ADC 212/50.
As a mobile guy, you would still be able to set up PicoScope so that it was as available as your AutoEnginuity. There are many ways you can deploy the equipment. Some examples can be seen here:
The equipment is very flexible and can be adapted for your needs. However, not something you will be able to use out in the rain The long leads would reach out from your van, or you could make it portable and use it in the customer's vehicle.
There is a learning curve, but we got your back Our library of tutorial movies is only the beginning. Once you get comfortable with it, you will not use anything else.
