Selecting the recording time/sample rate
How to select the recording time and the sample rate:
1. Select the desired time base from the time base list field.
• The current time base setting multiplied by ten results in the recording time.
• Since the measured data memory of the controller has a limited capacity, usually a
compromise is made between sample rate and recording time.
2. Enter the desired sampling rate in [ms] in the sampling rate input field.
By pressing the
button behind the Sampling rate input field, you open the Sampling
rate dialog box where you can also select the option Increased sampling rate:
Note!
When the option Increased sampling rate is selected, only integer multiples of 1/
(sampling rate in ms) are detected by the system.
• Since a complete representation in the oscillogram (10 * 1/(sampling rate in ms) *
(horizontal resolution in ms/Div)) requires + 1 measured values, but due to system-
dependent reasons only integer multiples of (1 / (sampling rate in ms)) can be
recorded, 1 ... 3 measured values may be missing at the left or right edges of the
oscillogram. The displayed curve then ends before the end or starts after the start of
the oscillogram.
• The curve that is recorded is not extended or compressed.
