Help me chose my first oscilloscope!

  1. Aug 12, 2018 #1
    So, I'm a student of electrical engineering and I want to buy an oscilloscope to learn more about stuff and have in mind some projects to do. At the moment I'm working on project "supervision of pellet furnace" with ESP8266 and automatic refilling. For that project I build my own schematic and board, but it has some problems and I want to debug it.
    So I need an oscilloscope, and also in next semester I have a course about oscilloscope and measure.

    My budget is 450€ max!

    1. I was looking at some models like Rigol ds1054z but i don't know if this scope is best buy for that money in 2018. (I will unlock to 100MHz if still can and all other things like I2C,RS232...)

    2. My main interest is digital electronic/microcontrollers/serial comunications (I2C,UART,RS232....)

    3. I want to buy a product that I can use for long, long time as a student and to do hobby stuff with it and maybe one day for work

    Please suggest me some oscilloscopes that will last.

    Thanks!

    Sorry if this topic doesn't belong here.

    Hi there

    welcome to PF :smile:

    tis a good place to post ... all us EE's hang out here

    The Rigol scopes are really good all round scope.
    I bought one for the last company I worked for and had no issues with it, worked well
    cant remember the model, it was around 8 yrs ago. From memory, it went to 50 MHz which was all I needed
    in that workshop as most stuff was audio systems with a rare bit of higher speed digital.

    Getting the 100 MHz option would be good
    Get a good extended warranty .... probably will cost you a few extra Euro. try and get coverage out to around 5 years


    have fun

    Another Dave ( I assume) reviews scopes and has a lot of great info... check it out over at www.eevblog.com

    If I recall correctly the RIgol had a pretty good review, I am also looking at the Siglent brand, he also did an interview with the founder.

    May also want to look at the Analog Discovery kit - students can get a pretty good discount.

    In the IK, there is a healthy supply of pretty cheap analogue scopes on eBay. No good for data analysis, of course but cheap and cheerful and you can rely on what you see as being what's really there. I would avoid the units that plug into a PC for a display. Not handy for fault finding. But 'chaque un a son gout' as they say in France.
    Just think long and hard about what you will actually want to do with it when you have it. :smile:

    Welcome to the PF. :smile:
    An option you should look into is the serial programmers and bus analyzers from TotalPhase. We use their Aardvark SPI/I2C programming pods and their Beable serial protocol analyzer pods here at work. They cost about $250 each, and are very handy when it comes do dealing with serial protocol issues. It's great if your 'scope can provide some of that functionality, but you will usually pay a lot more for those features in a 'scope, compared to just getting the TotalPhase pods.

    I also wants to buy an oscilloscope but they are very expensive, starting form $300, I dont need such kind of oscilloscope as my uses are limited. I came through this article https://circuitdigest.com/electronic-circuits/transistor-as-an-amplifier-circuit where they have shown such small pocket sized oscilloscope this looks cheap and fit for my work.
    I just want to ask where to buy this kind of thing?? It was not available on local shops even on big electronics stores.

    The case is marked "JYE Tech DSO".
    This is their website. https://jyetech.com/index.php

    Yes but the official site have only two payment options, Paypal and Google pay, which I dont have.
    I will try some other online vendors.
