Next to a good scan tool, I think having a good scope is vital to diagnosing today’s cars.
The scope you choose should be in line with your needs and your budget.
What Is A Scope?
This tool simply measures voltage and displays it on the screen.
The next tool is a Graphing DVOM. This tool now allows the measurement to be plotted on a graph over time, allowing the user to see the variances in the signal as they occur.
The DSO, too, graphs the voltage signal over time. The typical DVOM may sample at the rate of 200-400 samples per second, as compared to a good DSO with a sample rate of 20 MILLION samples per second.
HandHeld Scopes
Handheld scopes are more convenient than most PC-based scopes and often more user friendly, with built in databases and testing methods.
If cost is the primary factor, then the UEI scope/scan tool may be the choice for you. Having experience with the original UEI ADL7100 scope (I still have it!), I think most beginning scope users will find this scope more than sufficient for most testing needs.
PC-based Scopes
PICO scopes are at the forefront of automotive PC-based scopes, and are competitively priced to handhelds. Aftermarket Automotive Products and You Love Car
