1 Values measured under standard operating conditions (see page 19-11) after 30-minute warm-up and calibration with the time
base set to internal clock.
2 Values for a repeating phenomena.
The frequency bandwidth of a single burst frequency bandwidth is the smaller of the two values, DC to the sampling
frequency/2.5 and the frequency bandwidth of the repeating phenomena.

4 Typical values are typical or mean values. They are not strictly guaranteed.
5 No change in the acquisition rate with an increase or decrease in the number of channels
