Re: Sample Rate Limiting

You will need to sample at 8-10x the baud rate for good CAN reconstruction.

Here is an example of the insane power of the 4425 on CAN:

Re: European Auto Repair Shop - BMW specialized

We also are interested to know how to record a waveform ongoing/continuously instead of filling the screen, going away, then filling the screen again and having to capture it in that exact timeframe? Thank you! I think this will serve the purpose: https://www.autonerdz.com/cgi/yabb2/YaBB.pl?num=126...

Re: Attenuator for Picoscope 4425

Nice upgrade. 2 more channels and a lot more horsepower. The 20:1 attenuators will be just fine but you will need two more... It's essential to have one for each channel. The 10:1 attenuators are a better match for the 4425 and also increase the scope input impedance to 8 megohms. BTW... Might want ...

Re: Laptop specs

Our group is composed of power users. While minimal specs can certainly run PicoScope software, when you push the scope performance, it is PC resource intensive and some PCs will fall down. We recommend a minimum of a 2 GHz duo core processor with 4 gigs of RAM and preferably USB 3.0. More RAM is pr...

Re: PicoScope Automotive and PicoScope 2000 Series?

the 3000 series is still used throughout the world and is actually a better scope now due to the improvements made to the software. Hi Ben, New features, yes indeed, but the newer PicoScope builds have dummied down the block mode performance of the 3000 series. Would be nice if that performance cou...

Re: freezing waveform

Yup. 6.13.6.3775 is a broken build. I suggest you update.

Not aware of any such issues with the current build but it does have a bug with the RPM/Frequency measurement box.

Re: forward and reverse image options

I understand friend, but in this function that you mentioned moves the whole screen, in this option I had before it was possible to advance or delay only one signal example if I caught a wave of vacuum I could advance or delay it in relation to another signal as a signal. rotation What you want to ...

Re: Help for the newbie

I'm abit confused why I need to set to DC as these are Inductive crank sensor 2 wires in a shielded sheath, so I thought these produced AC output. It is a common misconception that AC signals need AC coupling. This comes from a misunderstanding of what AC/DC coupling does. Many of the automotive me...

Re: Advice needed on charging current waveform

We see it with some inductive crank sensors which can cause problems when looking at additional signals. This occurs when improperly hooked up to a floating ground VR sensor. Easy to create a no start condition with your scope. No active differential probe needed. Just hook up properly. What you do...

Re: 2 x 4 Software.

If that was technically possible, it would be ideal for everyone. Everyone that has a four channel would likely buy another as two could be used separately on different vehicles or combined in the less common circumstance when you really need 8 channels. So much more versatile. Pico would sell a LOT...
