  • Oscilloscope & Data Logging

    Greetings everyone,

    I've been working on a solid state device aside from my SSG and it appears that I'm achieving some amazing results from the data I've measured. My interest in radiant energy started as a hobby but because of these recent results I would like to pursue more accurate testing in order to confirm the data.

    I would like some recommendations on accurate testing and a good USB data logging hardware/software to use. I'm assuming 4 clamp probes would be needed to monitor voltage and current for input/output during charging and discharging.

    Any suggestions and advice is appreciated. Thanks in advance.

    Hi Eco,

    Cost and complexity /sophistication will depend most on one important factor:

    Sample Rate. So if you are monitoring average current with clamps, then if the clamps have DC outputs that you can run to a 4-channel PC-based data acquisition system... The cost will be much lower. The main concern with these is the sample rate of the box... that usually means it is divided down by the number of channels active. See "Iotech" or a slew of others... they start at about $500 but again, cost is dependent on Sample Rate. These allow direct storage to hard drive, and usually come with some analysis software that allow math functions, scaling, and the like, (or it can always be ported to Excel).

    If you need to capture 4 channels of complex waveforms, of high frequency... Then a 4 channel scope or equivalent is needed; or if not too high in F, what "oscillographic chart recorders" have become in the last 15 years (see "Astromed"), which is a meld of the 2 above with an optional paper output as well... both of these are much more expensive than a low sample rate DAS... but they are designed for long term recording.

    The "Data Loggers" you see advertised are generally very low sample rate (sometimes "1 second" is the fastest they will log).

      Current probes cost mega $$$

      I was looking at a "kit" a while back from tektronix . price tag - 14,000 dollars US. I couldn't afford it, but it was nice to look at.

        Yes I've been looking around and even a decent unit isn't cheap. I'm now thinking it might be better to get it professionally measured by an engineer instead of me buying all this gear, perhaps someone on the forum here would do it.

        I did get a DSO nano today and I have to say it's a nifty little pocket scope. What are the best points and methods to measure radiant output?

        I'm still open to suggestions on data loggers in the range of $200-400 or some sort of watt consumption analyzer with 3-4 digit resolution. Anyone?

          I'm like a kid in a candy shop with this oscilloscope. I've been working on this coil for 8 months and today I finally see what it looks like. Hopefully I have it hooked up right.

          In the background you hear whitenoise which is the coil.

          No sleep for me tonight.

            Hi Ecoman11, In the vid are you scoping your self resonating coil you showed in this thread http://www.energeticforum.com/renewa...iscussion.html

            Thats very interesting, if so you should make a thread about it when your ready. Oscilliscope is a very usefull thing, I was wanting to set up some data logging with my comp but I lack the time unfortunately.

            Cheers.

              These scope shots are from a regular coil and after that video I believe I damaged my oscilloscope trying to measure the output.

              I think what I have is beyond my knowledge for accurately measuring this device and I'm going to need some help from someone who has the proper equipment. I'm new here so I don't know who is who. Can anyone suggest a senior member or moderator to approach on this forum?

              I've been COP testing with the SSG datasheet and can say that my device at worst preforms battery COPs in the low 90s and system COPs and mid 80s. It's a unique device and worth looking into.

                Hi Ecoman

                I have just got an Owon PDS Rapid Electronics - Owon Technology PDS Series 2-channel colour oscilloscopes

                It has a USB output which I think can be used for data logging, however it is not clear from the manual what can and cannot be done via the USB. The price for this seems to me to be very good.

                Regards
                John

                  Thanks John.

                  What I need to outline here is that my device produces random frequencies and fluctuating current ranging from 200mah - 300mah so it is difficult to test without a fixed rate. I'm assuming a high sample rate data logger would be able to record the fluctuating current and voltages, but would probably cost thousands of dollars.

                  In this video you can see how the impulses come in waves which constantly changes the current and voltage. It's difficult to control but you can see at 10v/Div that it's producing some spikes that are off the scale.

                  YouTube - Impulses 2

                  So how does one go about accurately testing a device like this?
