Put the Analyzer into State Mode

To make a state measurement, you must set the analyzer to state mode. The state mode uses the clock supplied by the system under test to control when data is sampled.

1Press the Config MENU key.

2In the Analyzer 1 box, highlight the field to the right of Type, and press the Select key.

3Highlight State in the pop-up menu, and press the Select key.

Unless you are using an HP 1661 or an HP 1671 analyzer, your Configuration Menu will look different than the one shown below because your analyzer has a different number of data pods than the HP 1661, which was used to create the figure.

The analyzer is in state mode.

Pod A1 has arrows on the lower eight channels and the J-clock channel, indicating that transitions across the threshold voltage are occurring on these channels.
