Was checking out the pico site and found there is a now a 9000 series.

Sixteen bit and 5 Terra sample a sec 

Boy that new OTC scope with the 40Ms/sec has nothing on this.

Brandon,

The 3000 series will have no problem sampling a 50KHz signal at long time bases.  At 100ms/div or 200 ms/div, if you set up properly, you will sample at 1MHz per channel on each of four channels.  That would be 20x signal frequency. 

Sam,

That OTC spec of 40MHz is irrelevant without the record length spec.  I'll bet you no one will be able to tell you what the record length is.  There is a good reason for that   

(tom), to capture an intermittant i like to use 2 or 5 seconds per division,on cars this works great, diesels not so,it breaks up,i've seen bad connections of high current injectors only effect the middle section of the waveform and cause intermittent misses,so even with 2 million samples per screen i wouldnt be able to analyse enough to make a call on the fault (both captures are from same engine).................................(carl)heres an example of instruments avertised specs being beefed up,..my fluke 196c is advertised for a 100 megahertz 1 gigasecond samplerate, it is a  good scope in my opinion for quick diagnosis, but there is only a maximum of 1000-1200 samples on screen per channel,signal will look great as long as you dont use zoom(no buffer but high adc speed) glitch detect anyone?

Brandon,

I see.  There is a huge difference between your 2 millisecond capture and your twenty second capture.

Your 2ms capture is sampling at 10MHz with a sample interval of 100 billionths of a second.

Your 20 second capture is sampling at 100KHz with a sample interval of 10 microseconds.

You will still be able to capture this with a two second capture.  I see you have measured the time for one pulse at 18 microseconds.  With the 2 sec capture you will have 18 samples during this time.

The problem with your 20sec capture is that you only have one sample during an 18us period. 

Yes, you can push the most powerful automotive scope in the world too far
