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.
