Advice in oscilloscope needs

Former Member
Former Member over 10 years ago

Hi Guys,

Oscilloscope noob here! I am doing some various tinkering that I think I could use an oscilloscope for and I am wondering if the DS201 will do what I need. I have a bunch of old Commodore 64s that I would like to try and fix so I would like to check that the clock outputs from the various chips are working. Will the Nano be ok for this? Looking at thew review and the specs for the C64 I suspect not?

 

My other project is I am trying to interface a six button Sega Megadrive controller to a Arduino Pro Micro using the sketch from here: Sega Genesis controllers and Arduino revisited | Jon Thysell

However it is only working in 3 button mode yet the controller appears to work ok with a real megadrive so I want to be able to look at and measure the pulsed sequences that are sent to the controller so I can emulate them exactly with the Arduino. The pulse widths are around 20 microsecs but could be less. So do you think the Nano 201 will be able to show me what the exactly series of pulses being generated by the Megadrive are?

 

Obviously these are just hobbies so I am not looking to spend a lot of money but if it isnt going to be able to do what I need then I will look elsewhere maybe a second hand something? I have also thought that the Hantek 6022BE might be a better option perhaps?


Edit: Also I am wondering if what would be better for what i am wanting to do would be a logic analyser?

 

Thanks for the advice,

    It would be at its limits at 8Mhz because its sampling is only 48Mhz so even a 4* overhead would barly give you 10Mhz An alternate option is to purchase an older analogue scope. there are very good and…

    It's okay to buy a second hand analog scope. But It's also okay to buy a 2nd hand digital one. Since Rigol released their new DSxx4Z series, the price of second hand DS10x2's has gone down - almost to…

    Beginners should always get analog 2-channel scope with 20MHz bandwidth atleast. No point to get expensive DSO, as a first scope, especially second-hand. I learned this the hard way. My first DSO broke, but my 20MHz analog still works.

    Actually, my analog scope is my only scope, because i can't afford a new one.

    It's okay to buy a second hand analog scope. But It's also okay to buy  a 2nd hand digital one.

    Since Rigol released their new DSxx4Z series, the price of second hand DS10x2's has gone down - almost to pocket money level.

     

    (I've sold my analog 20MHz scope, bought a 1052 with the money and still had some change left to go to the pub image ).
