Pico has a built in technical library, but it is not vehicle specific with test points and wiring diagrams. Pico does not do raster or superimposed views. However, it will show you more detail and resolution on any waveform than anything you have ever seen.
Feel free to contact me if you have any questions on automotive application. The following are general guidelines when choosing a scope:
I do often get asked about what scope to choose. I don't
have an answer. You see, all scopes have their own set of
limitations. Some have more limitations than others :-p The
scope is only half the picture though. The tech is the
other half. You have to match the tech with the scope. The
most capable scope, not well matched to the user, is less
useful than a somewhat less capable unit that the tech
feels comfortable with. Almost any scope is better than
That being said, sample rate performance is very important.
All the cool features don't mean much if the unit can't
perform. So, I tell techs to first narrow the field by
evaluating the DSO sample rate performance of the units
considered. Then choose based on features from that group.
I have a web based DSO Sample Rate Calculator available to
perform this comparison based on the specs and the math,
not the manufacturer's hype. It enables you to objectively
compare DSO raw performance.
That calculator allows you to compare the sample rate
performance of digital scopes. All you need is two specs.
The max ADC speed and the sample buffer size. This empowers
you to determine the raw performance of DSOs you may be
considering so you can narrow the field of choices and then
focus on features on the short list. The features don't
mean much if a scope can't perform when it comes to sample
rate. You can ignore the manufacturer's hype, and make an
objective comparison using the math. This can help avoid
getting something that can't perform.
If the manufacturer can't tell you these specs for max ADC speed and buffer size (or record length), there are really only two possible reasons. Either they don't know, or are too ashamed to tell you. Neither is good...move on.
The Pico 3000 series automotive scopes have a 20MHz ADC and a 512,000 point buffer.
Vertical resolution is another consideration. It is a
separate issue from actual sample rate (horizontal
resolution) and indicates how small a voltage change can be
detected. If you can imagine horizontal grid lines on the
screen, an 8bit scope will have 256 of them. Voltage
changes between the grid lines cannot be detected or
displayed. The voltage must rise or fall to the next grid
line to be detected. A 12bit scope has 4096 grid lines so
smaller voltage changes can be shown. This results in a
waveform with more vertical detail or resolution. A scope
with lower vertical resolution will have more of a stair
step effect on voltage changes when examined closely. A
scope with higher vertical resolution will have a smoother
more finely defined waveform.
Pico automotive scopes are 12 bit.
