Time scale
Sets the horizontal scale for all channel and math waveforms in seconds per division.
Increase the scale to see a longer time interval of the waveform. Decrease the scale to
see it in more detail.
SCPI command:
TIMebase:SCALe on page 429
Acquisition time
Shows the time of one acquisition, that is the time across the 10 divisions of the diagram:
Acquisition time = Time scale * 10 divisions
Changing the acquisition time changes the time scale too.
SCPI command:
TIMebase:RANGe on page 429
Trigger offset
Adds a time offset to the reference point to choose the part of the waveform to be captured
and shown in the diagram. Thus, you can set the trigger outside the diagram and analyze
the signal some time before or after the trigger. Positive values move the trigger to the
right of the reference point to show the pre-trigger part of the signal.
SCPI command:
TIMebase:POSition on page 429
Reference point
Sets the zero point of the time scale in % of the display between 10% and 90%. The
reference point defines which part of the waveform is shown. If the "Trigger offset" is zero,
the trigger point matches the reference point.
SCPI command:
