Description of settings
Time Scale
Sets the time scale of the horizontal axis for all signals, in seconds per division. The
value is shown in the top information bar.
Increase the scale to see a longer part of the waveform. Decrease the scale to see the
signal in more detail. The scale has a point that remains fixed on the screen when the
scale value is changing - the reference point.
To set the time scale, you can also use the TIME keys.
Note: In FFT mode, the time scale may be restricted depending on the selected fre-
quency span, (see "Frequency Span" on page 107).
Remote command:
TIMebase:SCALe on page 257
TIMebase:RANGe on page 257
Horizontal Position
Sets the horizontal position of the trigger point in relation to the reference point. The
trigger position is marked by a colored triangle at the top of the diagram.
You can set the trigger point even outside the diagram and analyze the signal some
time before or after the trigger. In this case, the trigger marker is shown on the left or
right side of the diagram.
To set the horizontal position, you can also use the POS keys.
Remote command:
TIMebase:HORizontal:POSition on page 257
Reference Point
Defines the time reference point in the diagram. You can set the reference point in the
middle, or to the right to see the signal before the trigger. If the reference point is on
the left, you see the signal after the trigger.
Remote command:
TIMebase:REFerence on page 258
