Title: '04 Intrepid CMP & CKP
Post by Tom Roberts on Oct 9^th, 2004 at 7:10pm

Here is a capture of a 2004 Intrepid 2.7 DOHC cam and crank relationship. It was done using a Pico ADC 212/50.

There are twenty seconds on the above screen. :P One full engine cycle is framed between the cursors at 172.7ms.

Above is the same capture zoomed in 100x focusing on the engine cycle (2 revs) which was framed between the cursors.

I hate anyone who owns this scope setup, and will only begin to like them again after I own it too. :o ;)

Nice capture, Tom.

As you know, I have the 212/100 and is basically the same specs as yours when it's using 2 channels.

All I can say is............

Aliasing? What's that?

;D

Ok, took me a while but I finally found it. These captures are from a 2003 300M 3.5 V6 that I took last year.

Here it is zoomed out 50X.

And here it is zoomed out 100X. I think this one was idling at about the same speed as Tom's capture. :)

Pretty awesome scope.

Harvey.

Hey Harv,

Nice captures. I think your red trace is CMP and the blue trace is CKP though. Right? ::)

The new software has a cool added measurement which displays the number of samples collected for a channel. Mine was dialed up to 128,000 and I got 122,071 samles per channel. This is only one sample off from what the Autonerdz DSO Sample Rate Calculator comes up with. ;D

If you haven't got yourselves the Sample Rate Calculator, I highly urge you to do so. It, even more than helping differentiate scope capabilities, aids in understanding how a DSO functions. It has helped me greatly. Later, Matt.

I'm here with my little ole 212/3 taken apart and having a peak (which doesn't void my warrantee of course) and I see some really neat looking stuff in there. I'm not sure what all this stuff is exactly, but isn't there a screw or something I can turn to crank it up to 128K? Maybe I need to put one of those Superchips in it or something like that, no? :P

Carl, I think I hurt myself laughing ;D

Matt,

Glad you found the calculator useful. It's easier to understand, if you get the lesson that goes with it.

Unfortunately, there is some dis-information out there about how to compare scopes. Some of it is put out by otherwise reputable scope companies. I still have a lot of work to do to remedy some of the confusion that this causes.

Probably a subject for another thread. :P
