Acquisition Time

The process time between acquisitions depends from the selected settings and the selected
processing. Therefore it is not possible to catch the process time between acquisitions in a formula.
The next table gives an indication of the performance of the processing capabilities.
Process time between
acquisitions 500 ns/div
one channel
no trigger delay
acquisition length = 512
500 ns/div
two channel
no trigger delay
acquisition length = 512
average = 8
Equivalent time
Timebase:
- at 2 ns/div
- at 0.2 µs/div
Note 1: Time required to fill the acquisition record at the sampling rate corresponding with the
selected timebase setting is not included.
Note 2: After the specified time, there is a 99% probability of all sample positions being updated to
the new acquisition. Trigger frequency >2 kHz. These values are not tested in production
and are based on theoretical estimates and laboratory tests.
