THIS IS THE FINAL POST ….I have come to a conclusion to this matter and the 5000 series is a fantastic scope but an ok datalogger…Read further to get my results and closure. Well I FINALLY got someone at Pico to test a 5000 series with caps on the inputs and they got “similar” results to my “pattern...

Martyn,

I emailed them and have been working with them for a couple of days... I will Keep the forum posted

Bump... Just checking On the August 18th post and my offer...DJETH

Martyn… Just an offer… I would like to offer to go to Pico Technologies in Tyler Texas and take my desktop, laptop and both 5000 series scopes to test there. I could run my hardware at your facility for a day along with your team there running a their 5000 series scopes on PicoLog (recording the sam...

Section 7 Pico Scope file

All, Below is page 1 of the attached PDF document that I had to create because of the amount of data and files sizes... I am happy to get the originals to you if you can find a way for me to send you six 17MB files (although you requested only one...I am also attaching the Picolog file that I refere...

Martyn...
Sorry for the slow response. I am currently do not have access to the hardware but I will the middle of next week. I will post the results then.
What do you want me to record on the 4 channels? How many of each item...

Thanks DJETH

the other PicoScope attachments... You can look at the time stamps for the Picoscope and compare to the same time on Picolog...I don't see the same pattern regardless of the setup.

Martyn sorry for the delay and thanks for getting this to the development team… The team seems to be misunderstanding my problem. 1ms sample interval is the time base they are wanting me to test (which I did) but the time base I keep talking about is between 200ms and 1sec (which I also tested). I d...

Excellent... Thank You...DJETH

Bump... Martyn... checking if you have anything yet?

Sorry... But the website would not allow me to post my two 500kb .png pictures so I put them into a pdf

Martyn, when I looked at the first log using the "Latest Sample" setting I was reminded why I have not been using it...Too loud. Look at "Jul 17, 2020 11-20-56 AM 200MS Latest Sample". The temperature readings are pretty unreadable and need to be averaged. I turned the Latest sample to average on Ch...

Martyn, I will set this up and post the results... Channels A and C at 1 msec sample rate and B and D at 200 msec all set to latest sample when i do the recording... I have not seen the noise pattern on any sample rate less than 50 msec (that I remember) so should be interesting. What do you think a...

Well its not local interference... Here is a log that I took today about 30 miles from the other location... All inputs are capped (and set at 50mv) and am recording at 4 different time bases 100ms, 200ms, 500ms and 1 sec. You can definitely see the pattern. This is what I am seeing captured and tra...
