15.4 Block Sampling
Item
Specifications
Selectable range of the
• Time stamp mode
number of blocks
• When the arming source is EXT and the rest mode is OFF or when the arming source is AUTO
and the rest mode is event or time: 2 to 250
• When the arming source is AUTO and the rest mode is OFF: 2 to 1000
• When in hardware histogram mode: 2 to 1000
The total sample size of all blocks is within the maximum sampling size (see page 15-1).
