Pico 4 channel 4423

Post by Technician » Wed Sep 13, 2017 9:48 am

Hello,

I have downloaded the software for the 4423 scope and been spending time reading the online help along with learning to navigate my way round the menus of the scope functions. On the 4423 the channels A and B say 100V peak max, I have not found any information about these two channels to date, I am assuming that if I were to measure primary ignition waveforms I would not use channels A or B?

Or do I need the attenuators 10:1 and 20:1?

Any advice more than welcome, I'd like to start off using the scope on the right understandings :)

Use attenuators, I think Pico sells now 10:1 version.

Do you have a 4423 and if so which kit did you buy?

Ar no, I have a range of pico BNC leads and a Pico M1007 60MHz probe. All my other equipment is either Fluke, Sykes or Snap ON.

Technician,

The M1007 probe is really a T&M product; the lead is too short and not well suited to Automotive Mechatraonics they were a means to an end to measure FlexRay signals. I have a couple of them and they have never been out of the packets they came in!

Especially as the MI007 is supposed to be "tuned" before use and you will struggle to do that without a function generator. :cry: See https://www.picotech.com/download/manua ... 7.en-4.pdf

As a basic starting point I would advise you to invest in either of the lead sets below.

https://www.picoauto.com/products/test- ... a125-ta128

https://www.picoauto.com/products/test- ... a199-ta202

You will also need some 4mm croc clips and some backprobe pins, but you may already have these in your collection of other product.

The 4423 is not the latest Pico model but it is still a very capable scope see here for user manual / specs: :arrow: https://www.picotech.com/download/manua ... a-en-1.pdf

Do not worry about secondary at this stage as it sounds like you do not have the M1074's https://www.picoauto.com/products/ignit ... e-with-bnc
Or the PP400 set https://www.picoauto.com/products/ignit ... of-4-leads that you will need.

Along with some PP198 20:1 attenuators (not sure if these are still available from Pico direct but they are out there if you look.)

Main thing to remember about the 4000 series is that all the channel grounds are connected that can be a good thing in some situations and a bad thing in others.

As with all tools the Pico range of oscilloscopes are a great tool but they are massively enhanced by good training; the investment in which will re-pay itself many times over. The tool represents an opportunity! Training, knowledge, dedication and practice is what makes the whole thing fly. :D :D

Personally I've not found it any help that all grounds connected?

Thanks PicoKev for all the effort you have put in there, very much appreciated. :)

With regards to the leads sets a125 - ta128 and a199 - ta202, I do have a set of four of those leads but from the descriptions I can't make my mind up which set I have!!

I also have the early version of the ignition coil probe you mention above; https://www.picoauto.com/products/ignit ... gnal-probe

and I do have the set of spark plug leads you mention, and I have a CAN Test box similar to this; https://www.picoauto.com/products/break ... n-test-box, and loads of wire probes, clips adapters etc.

I just need a lot of practice now learning to use this marvelous scope :) and I am finally starting my two year refresher course in automotive electronics Monday evening :)

Hopefully I can start to provide real working examples of problem vehicles and receive some valuable knowledge and understanding from you more experienced professionals :)

What college? And what course? Link to course objectives would be good!

On a personal note please do not bother to quote large parts of, and or complete posts. It is entirely pointless, makes the forum slower to load and wastes bandwidth and data allowances for everyone. It also makes threads hard work to read and probably means that some people may not be bothered to reply and or help out. Nothing personal just my opinion! :P :shock: :D
