    Oscilloscope Specs. Question

    Post by merlot on Sat May 07, 2011 10:18 am


    I am looking at purchasing an oscilloscope. Specifically I am looking at the Rigol DS1052E. It costs about $400 (not too expensive) and seems to get good reviews. I've never used one before but have always wanted one. I want to learn more about them and will use it with my ST-70 and ST-120s. I will also be purchasing one of Roy's preamps once I figure out what I want.


    The specs are here:

    http://www.rigolna.com/products/digital-oscilloscopes/ds1000e/ds1052e/

    I am not sure how to read the specs and my question is this: The voltages in the amps are around say 500v. The input on the scope has a limit of 300v. There is a 10x attenuation switch on the probe. Can I use this oscilloscope to measure voltages etc. in the amps? Anything else I should think about?

    Appreciate your thoughts.

    I think for the amateur hobbyist, you are better served with a used Tektronix or similiar. I picked one up because like you, I always wanted one. Used them in college a little, and know the very basics.

    I found a seller on Ebay that was local to me, and offered a DOA guarantee. I had to buy the probes seperate but got some cheapies for $12 delivered, and the scope tested fine. Now had it not been local, it would not have been a good deal because the shipping would have been $50, and shipping was on me to return if it was DOA. I only paid $40 something for the scope. Sure, it's a Tek 50 mhz model 2225 scope which is older, but for I need it for, it's fine. If you are buying on ebay, nearly all of them do not have probes, and it's probably worth having a $12 set of probes to try out the scope when you get it. I got the probes on Ebay from a US seller in California. I also had to supply a computer cord to power it.

    Anyway, that's what I did, and I'm happy. I'm not ready to invest $400 in a scope that I will use a few times a year.

    Roy is selling a used scope right now on the parts forum:

    http://dynacotubeaudio.forumotion.com/t115p30-place-for-sale-or-wanted-audio-related-items-in-this-sticky-thread

    It's an older B&K but the price is right.
