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...

Re: 8-Channel Oscilloscope for Automotive?

Nice write up, Steve.

One correction needed:
Sample Rate 10MS/s with all channels active (Which remains impressive)
It's 40MS/s with all eight active is it not?

Re: Raster Parade, etc,..

No problem, Ben. As the original Pico automotive vendor, we have some history. Here is some on the Mixmaster. The Mixmaster was inspired by one of our members who came up with a technique for looking at the entire secondary ignition for all cylinders on a waste spark system using tandem Ferret 953 u...

Re: Raster Parade, etc,..

As PicoKev has mentioned we do have the MixMaster which will allow you to connect to a V12 using just two channels of your scope. Whilst not in Raster it will give you the ignition waveforms in Parade using a trigger from cylinder 1 and the king lead to acquire all ignition patterns. Ben, No Mixmas...
