Maximum record length for which a single acquisition is possible. Values inside parentheses apply
when interleave mode is on.
No options:
6.25 M points (12.5 M points)
On models with the /M1(S) option: 25 M points (62.5 M points)
On models with the /M2 option: 62.5 M points (125 M points)
On models with the /M3 option: 125 M points (250M points)
1 Values measured under standard operating conditions (see section 5.11 for details) after a 30-minute warm-up and calibration.
2 Values for repeating phenomena.
The single-shot frequency bandwidth is from DC to the sampling frequency/2.5 or is the frequency bandwidth of the repeating
phenomena, whichever is less.
3 Values when the input section is shorted, the acquisition mode is set to Normal, accumulation is set to off, and the probe
attenuation is set to 1:1.
4 Typical values represent typical or average values. They are not strictly warranted.
