Logging Measurments

Postby dbertenshaw » Tue Sep 13, 2016 4:38 pm

I should like to log measurements on Picscope6 automatically. The ideal is to link it to PicoLog which has all the features to log and record measurments. I know that there is the /a Measurements automation feature for people to DIY something but sorting out the scripts with Excel so one can record time-stamped multiple measurements is a bit beyond me. Has anyone either linked it to Picolog or written the neccessary macros for Excel?

Thanks for the interest.
I have both the 4224 and 5203, but the 4224 is the more important at the moment due to its analogue accuracy.
I also log the TC-08 with Picolog.

Unfortunately the two scopes you have will only work with the PicoScope software, and there is no way to share data between the two applications.

You could try emailing support@picotech.com for suggestions although it is likely to involve using the SDK to collect the data and calculate the measurements, possibly directly within Excel.

The idea of learning and coding from the SDK does not appeal, when the Picoscope app already does the measurement computation, and enables me to visually see and align the traces and bars between which measurements are made (SDK I doubt allows this).

The alternate is the idea of macros in Excel using the /a automation facility in Picoscope. This can extract the 2 or more measurement values directly; the challenge is to parse them into columns and repetitively log with time-stamps.

It seems such a useful feature to me, am I so alone?

We are looking at a more direct export of measurements, as we enhance the software, but that is not on the short term plan.

I too would benefit from Picolog working with a wider range of Picoscopes. The 3XXX series particularly.

The driver model for the current scopes, the speed they operate at, and the number of samples they collect mean that adding support for them to PicoLog is not an option. Sorry.

Sorry Martyn, but this is all the more reason to provide a simple (DDE?) link for measurement data from Picoscope to Picolog. Picoscope allows for some very advanced measurements to be made, well outside those possible by classic test instruments. However recording the results and especially how they vary with other parameters, remains in the stone age!

Personally I dont understand Pico's reticence. They PR they could get from it would be massive, as an easy to setup Labview-like test harness.

We are looking at the measurements processing engine for PicoScope 6, so all feedback on this is welcome.

Linking PicoScope 6 to PicoLog is not an option, we are nolonger developing the existing PicoLog application, it is in maintenance mode.

That Picolog is dying is sad to hear. The related products, TC-08 etc, are well spec'ed and easy to use with Picolog.

it is however good news that Pico is going to do something useful with measurements. I assume that Pico does not want to rewrite Picolog to make it universal for all products? If so then it would be better to make the measurements acessible to 3rd party dataloging software. The most obvious is the free NI Software Express LE. Also very affordable is the UK Windmill logging software package which I use. I guess every client will have their own favorite, but since it is very likely that Picoscope measurements will be logged with data from other instruments, Pico will have to chose some industry standard if it does not want to go through the pain of developing a universal open logging package.

Good luck and poste haste!
