The status of the timer/counter value can be checked by tapping
“Timer/Counter” from [
] even during measurement.
Tap “X” on the window to finish the display of timer / counter
value.
6.3 Timing Waveform Measurement Function
It is possible to measure the timing of change of the communication line with a time resolution of up to 50nsec and
display it as a waveform like a logic analyzer do so.
Setting
Display the top menu screen by [MENU] and tap “Wave monitor
”. When using the timing waveform measure
-
ment function, check “Enable wave monitor” on the wave monitor setting screen and set the items.

Sampling clock
Tap the item and select the sampling clock cycle that is 5 to
10 times faster than the communication speed of the measure-
ment target from 50nsec, 100nsec, 200nsec, 500nsec, 1μsec,
2μsec, 5μsec, 10μsec, 20μsec, 50μsec, 100μsec, 200μsec,
500μsec, and 1msec.
For example, when analyzing 38400bps timing, select about 2
μsec or 5 μsec.
ڦ
Trigger position
Tap the item to select the trigger position of the waveform
monitor. Set the trigger position in the waveform monitor
sampling memory (for 2K sampling) depending on which part
of the waveform measurement data -before or after the trig-
ger- is prioritized.
Before : Captures some data from the trigger point and
then stops.
Center : Stops at the point where before and after parts
of the trigger have the same amount of data.
After : Captures a lot of data from the trigger point and
stops.
