Trace Time Axis Change
This function changes the time axis displayed in the data trace. The data trace time
axis is displayed below.
a. Select Sampling (S) ⇒Trace Time Axis (T) from View (V) in the data trace
menu.
b. Set the time axis and sampling interval in the dialogue box and push the OK but-
ton.
c. The trace time axis display is switched, and numerical data is displayed.
Note:
It is necessary to input the sampling interval into the dialogue box in (b) when setting Pro-
gram into the Execution Timing box in the Trace Definitions tab, and changing the time
axis to Time Display A or Time Display B.
Important Points - Trace Time Axis
There are four types of trace time axes: TIMEA, TIMEB, SNOA, and SNOB. The mean-
ing of each time axis is as follows:
TIMEA
This displays trace data in time units assuming the time at which tracing starts to be 0.
Therefore, 0 is the newest trace data. The data is traced for each scan set in the Scan Time
Setting screen. The display units are 1s and 0.01s. The units can be alternately displayed
by selecting Data (D)
⇒m/s (M) from View (V) in the Data Trace menu. 01.000 equals
one second in 1s units. 0.01s equals 0.01 seconds in 0.01s units. However, the decimal
point position changes depending on the trace time width. 01.000 and 1.000 are the same.
TIMEB
This displays trace data in time units assuming the time at which tracing stops to be 0.
Therefore, 0 is the oldest trace data. The data is traced for each scan set in the Scan Time
Setting screen. The display units are 1s and 0.01s. The units can be alternately displayed
by selecting Data (D)
⇒m/s (M) from View (V) in the Data Trace menu. 01.000 equals
one second in 1s units. 0.01s equals 0.01 seconds in 0.01s units. However, the decimal
point position may change depending on the trace time width. 01.000 and 1.000 are the
