Timebase

Timebase, also known as Horizontal, settings control the trace along the X axis. The timebase is shared by

all channels.

The time represented by each horizontal division of the grid, or Time/Division, is most easily adjusted using

the front panel Horizontal knob. Full Timebase set up, including sampling mode selection, is done on the

Timebase dialog, which can be accessed by either choosing Timebase > Horizontal Setup from the menu bar,

or touching the Timebase descriptor box.

The Timebase dialog contains settings for Sampling Mode, Timebase Mode, Real Time Memory.

Timebase Settings

Sampling Mode

Choose from Real Time, Sequence, RIS, Roll, or Average mode.

Timebase Mode

Time/Division is the time represented by one horizontal division of the grid. Touch the Up/Down Arrow

buttons on the Timebase dialog or turn the front panel Horizontal knob to adjust this value.

Delay is the amount of time relative to the trigger event to display on the grid. In Real Time sampling mode,

the trigger event is placed at time zero on the grid. Delay may be time pre-trigger, entered as a negative

value, or post-trigger, entered as a positive value. Raising/lowering the Delay value has the effect of shifting

the trace to the right/left, enabling you to focus on the relevant portion of longer acquisitions.

Set to Zero returns Delay to zero.

Real Time Memory

Maximum Points is the maximum number of samples taken per acquisition. The actual number of samples

acquired can be lower due to the current Sample Rate and Time/Division settings.
