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. The scale has a point that remains fixed on the screen when the
scale value is changing - the reference point.
Remote command:
TIMebase:SCALe on page 1188
Acquisition time
Shows the time of one acquisition, that is the time across the 10 divisions of the dia-
gram:
Acquisition time = Time scale * 10 divisions
Changing the acquisition time changes the time scale too.
Remote command:
TIMebase:RANGe on page 1189
Position
Defines the time distance between the reference point and the trigger point (the zero
point of the diagram). If you want to see a section of the waveform some time before or
after the trigger, enter this time as horizontal position. The requested waveform section
is shown around the reference point. Use positive values to see waveform sections
after the trigger - the waveform and the diagram origin move to the left.
See also "Reference point" on page 142.
Remote command:
TIMebase:HORizontal:POSition on page 1189
Reference point
Sets the position of the reference point in % of the screen. The reference point marks
the rescaling center of the time scale. It is indicated by a grey triangle outline at the top
of the diagram. If you modify the time scale, the reference point remains fixed on the
screen, and the scale is stretched or compressed to both sides of the reference point.
Remote command:
TIMebase:REFerence on page 1189
Restrict horizontal position to acquisition range
If enabled, the horizontal position cannot be set outside the visible waveform diagram.
Remote command:
TRIGger<m>:OFFSet:LIMited on page 1190
