The test is simple:

1. Set gain to 10mm/mV.

2. Input a triangular wave.

3. Adjust input signal amplitude to 100% full scale peak-to-valley output.

4. Decrease input signal amplitude by factors of 2, 5, and 10.

Success criteria:

For each signal amplitude in (4), the displayed output shall be linear within ±20 % or ± 100 μV of the full scale output.

My question is:

How do you interpret the success criteria? I'm assuming the +/-20% is allowing a margin of error for output signals that are not perfectly triangular, which means it's acceptable to have a noisy/distorted signals?

I'm currently interpreting this as a 20% linearity on a single test case. It's not making sense to me on how this 20% applies to the full scale output.

Any help would be greatly appreciated.

Thanks.
