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 1109
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 178.

TIMebase:HORizontal:POSition on page 1109
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 1109
Sample rate
Sets the number of captured waveform points per second. It considers the samples of
the ADC, and the reduction of waveform points by decimation.
If interpolation is not active, the sample rate is the reciprocal value of the resolution
and thus also depends on the acquisition time and the record length.
If interpolation is active, the sample rate is limited to the ADC sample rate.

Resolution
Sets the time between two waveform samples. A fine resolution with low values produ-
ces a more precise waveform record.
Remote command:
ACQuire:RESolution on page 1112
Record length
Indicates the number of waveform samples that build the waveform across the acquisi-
tion time.
