    I have been looking at the Tektronix TDS2014C
    (100 MHz, 4 Ch, 2 GS/s, TFT DSO) Oscope.

    I was initially looking at the Tektronix TDS2004C
    (70 MHz, 4 Ch, 1 GS/s, TFT DSO)

    For an entry level scope are either of these good pieces of equipment? I will be looking at mostly microcontroller applications with a max frequency of maybe 32-64MHz most likely lower freq tho, some stepper motor control and maybe optical encoders.

    Is the extra 300 dollars worth the higher model?
    +30mhz bandwidth and double sample rate. also the 100MHz model comes with 200MHZ probes, the 70MHz only comes with 100MHz probes. I have heard that its good to have probes rated double your max bandwidth is that true?

    datasheet



    Alternate recommendations?

    If I was going to be doing anything at 64MHz then I'd be looking at 300MHz bandwidth scopes at a minimum, but 500MHz+ would be ideal. Bring your checkbook, especially if you want a tek. If you're looking to do serious uC stuff then a 4 channel o-scope with MSO is a must.

    100MHz bandwidth might be able to work with 20MHz signals, at most.

    A general rule of thumb: scope bandwidth = operating speed * 10. You can probably get away with operating speed * 5, but that's pushing it.

    Check out the Tek MSO3054 - we have a few of these at work - they are great scopes.
