Title: Pico scope 9000 series Post by jarvissamuel on Dec 4th, 2008 at 10:33am
Was checking out the pico site and found there is a now a 9000 series.
http://www.picotech.com/picoscope9000.html Sixteen bit and 5 Terra sample a sec :o Boy that new OTC scope with the 40Ms/sec has nothing on this. |

that would come in handy, diesel engine injector drivers run around 50,000 hz nowadays(common rail), its impossible to veiw any detail when theres more than 100m/s per div on screen (when zooming), wave form breaks and looks real funny, 12,500 dollars do they give you a car for a carrying case :D

Title: Re: Pico scope 9000 series Post by Tom Roberts on Dec 4th, 2008 at 4:14pm 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 :P |

Record depth is highly important when choosing a DSO for our timebases in automotive. The 3000 series scopes can handle this task with ease at longer timebases.
The incredible thing is free software updates which improve performance and support that is always there to answer any questions. |

(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?

if i had the morgage to buy a pico 9000,i figure if it had a streaming mode,which not sure if it does,my last post would look like this at 2 seconds per division? :P

Title: Re: Pico scope 9000 series Post by Tom Roberts on Dec 5th, 2008 at 8:02am 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 ;) |

Hi Tom
You are correct that OTC has not officially released the size of the buffer. I recently attended a class on the tool and asked that specific question. Interesting answer of 60gig was related then I finally explained I wanted to know the number of record points per screen. That was unknown. I did have a chance to play and have comparison on you tube. I think there is a linke embedded in the open forum under is this cheating? The resources are better than the original but I did not have a chance to completely compare it. That probably would not be fair to OTC anyway ;D Sam |
