Making a Measurement

This section discusses the methods for making measurements after con guring for
measurement.

Triggering a Measurement

The 4349B has four trigger source modes: Internal, Manual, External, or Bus. The Trigger
annunciator( ) shows which trigger source is selected.

To Trigger Manually
1. Press until the Man annunciator(
2. Press to trigger a measurement.
To Trigger Externally
1. Connect an external trigger source to the Ext Trigger terminal on the 4349B's rear panel.
2. Press until the Ext annunciator(
3. Apply a TTL level trigger signal to trigger a measurement. (Refer to \External Trigger
Terminal" in Chapter 3 for trigger speci cations.)

To Use the Comparator Function

The comparator function can be used to sort DUTs according to user set parameter limits.
To set the limit values:
1. Press to select the channel to set.
2. Press .
