1 Under standard operating conditions (see section 6.11 for details) after a 30-minute 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.
