1 Under standard operating conditions (see section 6.11) after warm-up
2 Typical values represent typical or average values. They are not strictly warranted.
3 Resolution only improves for analog waveforms.
4 If high resolution mode is off and the sample rate of analog channels is 2.5 GS/s, interpolation (sampling) mode is used.
5 Repetitive sampling is not possible when the trigger source is set to logic input.
6 At record lengths that only odd channels can use, acquisition is not possible for logic input.
