SET UP SEQUENCE MODE

When setting up Sequence Mode, you define the number of fixed-size segments acquired in single-shot mode

(see the instrument specifications for the limits). The oscilloscope uses the sequence timebase setting to

determine the capture duration of each segment. Along with this setting, the oscilloscope uses the number

of segments, maximum segment length, and total available memory to determine the actual number of

samples or segments, and time or points.

1. From the menu bar, choose Timebase > Horizontal Setup....

2. Choose Sequence Sampling Mode.

3. On the Sequence tab under Acquisition Settings, touch Number of Segments and enter a value.

4. To stop acquisition in case no valid trigger event occurs within a certain timeframe, check the Enable

Timeout box, then touch Timeout and provide a timeout value.

NOTE: While optional, Timeout ensures that the acquisition will complete in a reasonable amount of time

and control of the oscilloscope will return to the operator/controller without having to manually stop the

acquisition.

5. Touch the one of the front panel Trigger buttons to begin acquisition.

NOTE: Once acquisition has started, you can interrupt it at any time by pressing the Stop front panel

button. In this case, the segments already acquired will be retained in memory.

VIEW SEGMENTS IN SEQUENCE MODE

When in Sequence Mode, you can view individual segments easily using the Zoom dialog. The Zoom trace

defaults to Segment 1. You can move to later segments by changing the values in First segment to display

and Num(ber) of segments to display at once.

TIP: By changing the Num field value to 1, you can use the front panel Adjust knob to scroll through each

segment in order.

Channel descriptor boxes indicate the total number of segments acquired. Zoom descriptor boxes show the

number of segments displayed. As with all other Zoom traces, the zoomed segments are highlighted on the

source trace.
