Symbol/Field Description
6 Ground Reference The ground referenceof the trace. Ground references areoffset so that they do notoverlap. The
ground reference offset valueis referenced to the horizontal center line of the grid.
8 Trigger PointIndicator Indicates the trigger position in the data log. In this example the trigger point was offset by 50%,
and the pre trigger data and the posttrigger data was logged. The timeatthe trigger point is
always zero. Changethe trigger offset in the Datalogger Trigger Properties window.
9 Time/Div. Identifies the horizontal time-base setting. This can be adjusted using the front panel Horizontal
Time/Div knob.
10 Left-Grid Time Identifies the timeatthe leftgridline in relation to the trigger point. If the trigger is at the leftof the
grid, the time will be zero.
11 Filename Indicates the filename of the data that is being displayed.
12 Right-Grid Time Identifies the timeatthe right gridlinein relation to the trigger point. If the trigger pointis at the
start of the data log, the timewill equal the total duration of the data log.
13 Trigger Source
Amplitude
In the figure, the trigger source is a voltage level on output1. The Data Logger starts logging data
when the indicated level is reached.
Up trigger indicates the data logger will be triggered on the up-slope (positive).
Down trigger indicates the data logger will be triggered on the down-slope (negative).
If the trigger source is set to a voltage or currentlevel, the amplitude of the trigger level is
indicated belowthe trigger source. In the figure, the voltage trigger level is set to 2 V.
14 OffsetTime Indicates the time that the rightgridlineis offset or away from the end of the data log. When this
valueis zero, itmeans thatthe right gridlineis positioned at the end of the data log. Turning the
offset knob will move the grid away from the end of the data log, as indicated by the Offset Time.
The yellow part of the bar represents the datathat is visible on the display. Theblack part
represents the offset time.
