 |
|
Hi all,
I would greatly appreciate some advise to help me choose between the 2-channel and 4-channel Picoscope Automotive kits.
As I am a complete beginner in the use of oscillopscopes for automotive testing, I have no idea if I would restrict myself by purchasing the 2-channel scope instead of the 4-channel.
If there are meaningful Automotive tests which need 4-channels, then I would choose for the 4-channel scope.
Any comments and thoughts gratefully appreciated.
Regards from the Netherlands,
Brian. |

Hi Brian,
You can get the job done with two channels. However, it may take a bit longer and there are some limitations.
If you were to add a Mixmaster ignition mixer for capturing waste spark secondary ignition, using a two channel, you would have to choose between splitting the banks by polarity between two channels or trigger. To split banks and trigger requires three channels.

There is another example of when four channels can be handy in reply #7 of this thread on EDIS cam sensor syncronization:

There are many other examples on The Autonerdz Community Forums and also a few more four channel example pictures here:

I would suggest the four channel, if you can afford it. It's more expensive to upgrade later.

You are welcome. I hope it was helpful.
No matter which way you go, you are making an excellent choice getting a PicoScope. These are the most powerful automotive scopes anywhere.
I got my expertise by making more mistakes than everyone else 
Now we teach others how to avoid them. Guess the purpose of my life is to serve as a warning to others. 
Now we have customers on six continents including a couple of your neighbors in The Netherlands.  |
