Introduction to Timing Analysis

Trigger on the Term and Examine the Waveform

Trigger on the Term and Examine the Waveform

When you press the Run key, the analyzer triggers on the term you set up in the previous exercise, captures the data, and then switches to the Waveform menu where the data is displayed.

1Press the Run key.

2Use the table below to examine the waveform.

To Do This:

To scale the waveform

To scroll through the waveform

To measure a time interval

Do This:

Highlight the sec/Div field, then turn the knob clockwise to zoom in and counter clockwise to zoom out. If you zoom out enough you can view the entire acquisition buffer.

Highlight the Delay field, then turn the knob in either direction to scroll through the data.

Highlight the Markers Off field, then press the Select key. Choose Time from the pop-up menu. Highlight the Trig to X field, then turn the knob to move the X marker.

Triggering on the Term and Examining the Waveform

As you move the X-marker past transitions on the waveform, the hex value to the right of X-> changes, showing you the value of the TCOUNT label at the current X-marker position.

3 Highlight the Markers Time field. Press the Select key, then select Off.
