Re: Attenuator for Picoscope 4425

Thanks for prompt reply and yes, you are right. I need to buy more attenuators for each channel.

Attenuator for Picoscope 4425

I am going to upgrade my old PicoScope 4223 2-CH to Picoscope 4425. I wonder if I can still use my 20:1 attenuator for the Picoscope 4425 or I need the new one 10:1 for it? Thanks.

Re: Alternator Ripple waveform

I finally figure out was the scope itself problem. Pico exchanged me with a new one and I will test again.

Alternator Ripple waveform

Hi, I have attached a screenshot of the alternator ripple waveform. This is a 2001 Camry Lx. I followed the instruction from the picoscope 6 automotive to connect to the battery and let the car ran idling. The waveform was looked very strange and I believed there was something wrong with the alterna...

FIRSTLOOK SENSOR WAVEFORM

Hi Matt, Thanks for your reply. Does it mean the waveform is looked normal? Actually, how can we determine if the waveform from FLS is normal? Besides, I do have some waveforms from 1996 Camry, 1996 Prelude that also used FLS but they all looks terrible. If you don't mind to take a look, I would lik...

Hi Matt, Thanks for your response. I need to explain more clear. I connected the FLS to the tail pipe but not the intake manifold. About the synchronize problem. As you see the attached waveform, there are only 2 peaks in between the trigger. I assume there should be 4 peaks because this 98 Beetle i...

I triggered with the 4th cyl spark plug wire because it is the easiest one to access but it seems the pulse from the FLS was not syn...
