Re: Measuring current and voltage using PicoLog 1000

Putting a resistor in the ground return path in this way this means you can't select a value to give access to the full 2.5V input range of the logger as this would raise the ground potential on your device by 2.5V (not good). It needs to be a small value resistor to give a minimal voltage drop but ...

Re: Measuring current and voltage using PicoLog 1000

Using the bennog modification to the circuit fit the resistor in position R4 on the terminal board to measure the current in Ch2. However this will cause the ground level on your device to rise, V = I*R so the resistor needs to be small enough so as not to cause a problem, but big enough so the volt...

Re: inductive impedance speaker measuring

Can you post a psdata file of the data you have collected, some pictures and/or sketch of your setup so we can see what you are connecting where, and a description of the results you would expect to see.

You can do this here or send the details to support@picotech.com

Re: 2205A no DC

Does this happen on both channels ? Do you here a relay click when you switch between DC and AC coupling, or when you switch from high range to low range ? It's possible that there is a hardware fault that is leaving the DC blocking capacitor switched in circuit. I would suggest emailing support@pic...

Re: 5242B Unable to run software 6.14.10

Does the software run in demo mode when the scope is not connected ?

Re: Best practices for using a large number of scopes

Would you want to use the PicoScope 6 software ? or would you be writing your own application to control all the devices ?

Re: Carrying/storage case for PicoScope 2205A

We do not have a carry case specifically for the 2205A. You may be able to add additional inserts into the one you have linked to keep your device from moving, otherwise you will need to look for an alternative from elsewhere.

Re: Obtaining continuous triggered data

The issue is going to be the transferring of data over the USB bus and where in the process this happens. There are three different approaches that you can take :- 1. Streaming data but only saving out what you need You can stream continuously with a 6.4nsec sample interval for a single channel (or ...

Re: Two Signals - Two Grounds

Although what bennog has suggested sounds possible I would suggest drawing out your setup to understand all the voltage levels and exactly where the signals sit in relation to mains earth for the PC and hence the scope. Post the sketch here or send to support@picotech.com for further advice. Do not ...

Re: P5000A RatioMode.Decimate

What exact issue are you seeing? If you need to sample at an interval of 40nsecs then you should not use decimate as this ignores many of the samples you collect. For example if you collected 100 samples at your chosen rate of 40nsecs and then for example you decimated by a factor of 10 you would ju...
