Using the Dual ARB Waveform Player

Playing a Waveform

This procedure applies to playing either a waveform segment or a waveform sequence. This example plays the waveform sequence created in the previous procedure.

1.Select a waveform sequence:

a.Press Mode > Dual ARB > Select Waveform.

b.Highlight a waveform sequence (for this example, TTONE+MTONE) from the Sequence column of the Select Waveform catalog, and press Select Waveform.

The display shows the currently selected waveform (for example, Selected Waveform: SEQ:TTONE+MTONE).

2.Generate the waveform: Press ARB Off On to On.

This plays the selected waveform sequence.

During the waveform sequence generation, the ARB and I/Q annunciators activate.

Editing a Waveform Sequence

This example shows how to edit waveform segments within a waveform sequence, and then save the edited sequence under a new name. Within the editing display, you can change the number of times each segment plays (the repetitions), delete segments, add segments, toggle markers (described on page 97), and save changes.

NOTE If you do not store changes to the waveform sequence prior to exiting the waveform sequence editing display, the changes are removed.

1.Press Waveform Sequences > Edit Selected Waveform Sequence, and highlight the first entry.

2. Press Edit Repetitions > 100 > Enter. The second segment is automatically selected.

3.Press Edit Repetitions > 200 > Enter.

4.Save the edited file as a new waveform sequence:

a.Press Name And Store.

b. Press Editing Keys > Clear Text, then enter a new file name (for example, TTONE100+MTONE200).

c. Press Enter.

You have now changed the number of repetitions for each waveform segment entry from 1 to 100 and 200, respectively. The sequence has been stored under a new name to the Catalog of Seq Files in the signal generator’s memory catalog.

For information on playing a waveform sequence, refer to page 86.

Adding Real-Time Noise to a Dual ARB Waveform

The signal generator with option 403 can apply AWGN (additive white gaussian noise) to a carrier in real time while the modulating waveform file is being played by the Dual ARB waveform player. The AWGN can be configured using front- panel softkeys. The Carrier to Noise Ratio softkey allows you to specify the amount of noise power relative to carrier power that is applied to the signal.
