Re: Yoogawas flow input in PT104

Hi Sameer, How do you know that the input voltage is "correct" (how are you measuring it)? It would help us to help you if you could post a diagram, along with some images of how you have everything connected up (to the pins of the the terminal board). Also, if you could tell us what output range yo...

Re: Can not load .plw files in PicoLog6 recorded with PicoLog 5.22.8

Hi Terry, The short answer to your question is NO, you will not be unable to work with your many old recordings , because they will still be viewable in PicoLog 5, if you have re-installed it in compatibility mode. As Picolog 5 is a tiny program I can't see many people needing to get rid of it becau...

Re: How to interpret this pop-up display?

Hi Terry, You might want to check your email, because a reply was sent to your help desk query on this. When you click to display the cursor value, the window is showing you the co-ordinates of where you are actually clicking on the Channel scales, not the value of the signals on the Channel scales....

Re: PicoScope 4262 noise floor has significant spurs

Hi Dan, I had to create a quick answer for you as I was going to be out of the office for a while. So, I've made the below explanation more comprehensive for the benefit of other forum users. As already mentioned, you have to keep in mind that the Spectrum plot of a PicoScope is not a digital Spectr...

Re: How to interpret this pop-up display?

Hi Terry,

It would be better to post the data files so that we can investigate what is happening?

Re: Problem with data dropout

Hi Tim,

Exactly how cold is it?

I would suggest checking the specifications of everything in your setup to see what their operating ranges are, and then comparing that against the actual temperature.

Re: Picoscope 4444 THD measurements

Hi Imbrondir, A simple way of getting the % nth harmonic distortion would be to make two %THD measurements setting the 'Highest Harmonic' in the measurement options of the % THD mesurement to n for the first and n-1 for the second, and then subtracting the second value from the first. I have created...

Re: PicoScope Software and own application at the same time

Hi Andreas,

No you can't, because software needs to be given the 'Handle' of the scope to access it, and there is only one 'Handle' per scope.

Re: Continuous Taking Data

Hi Kate,

This will depend upon:

1/ the Model of PicoScope that you have
2/ the sample rate that you need to use
3/ the number of input channels you will be using
4/ whether or not you need to capture data before the trigger as well (and if so for how long)

Re: How to log all active channels with Alarm trigger

Hi bboyes, Here is an example PS3425 psdata file with the alarm setup to capture and automatically save to disk all active channels (not just the trigger channel). I've set it up to restart the capture so that it automatically continues, but if you don't want that behaviour, then just remove the las...

Re: PicoScope 4262 noise floor has significant spurs

Hi Dan, The PicoScope 4262 would not have the same sort of front end as the HP analyzer, as the frequency domain processing is not a hardware function (so it is not even a digital spectrum analyzer, i.e. it doesn't capture a spectrum of frequencies and then transform the analogue values of those fre...

Re: Deciding between 2000 and 3000 series

Hi tstalcup, I have created a screenshot and data file to show you what was possible with my PicoScope setups in both the 32033D and 2406B PicoScope models. From your screenshots it appears that you have a 5ms Timebase with a 100MS/s sample rate for a 7M point capture, and what appears to be a wavef...

Re: Picoscope 3000 i2c serial decoding

Hi jgleason, The Address + R/W bit field just includes the last bit in the address encoding (shift or shift + 1) because some vendors of I2C comms based devices include the R/W bit in their address frames to create 8-bit addresses, although, officially this is against the convention of the spec wher...

Re: Poor bandpass filter :-(

Hi Knud, The Maths Channel bandpass filter is effectively a single pole filter, so you only get a gentle roll off of between 3dB and 6dB/octave (there is no resonance). So, there will be a practical limit to how small you can set the bandwidth of the bandpass filter, before the filtering effects sta...
