    <p>I'm not familiar with that model. I've 1000s of hours using
      scopes mainly (99.99%) Tek scopes.</p>
    <p>What I will say about buying an used scope is unless it comes
      with a current (less than a year old) calibration certificate add
      the bucks it costs to get calibrated it professionally if you want
      accurate measurements. That might get rid of the offset. No you
      shouldn't need a short probe to test the offset, no probe should
      work.</p>
    <p>Personally I thing getting one of the cheap digital scopes now
      days is a better option. You have digital measurements and bus
      decoding which make life a lot easier than having to count ticks
      and do math for measurements and manually decode buses.</p>
