Custom Digital Modulation (Option 431)
Using the Arbitrary Waveform Generator
Recalling a Custom Digital Modulation State
Using this procedure, you will learn how to recall a custom digital modulation state from signal
non–volatile memory.
If you have not created and stored a user- defined, single–carrier, digital modulation state, complete
the steps in the previous sections, Creating a Custom Digital Modulation State on page 339 and
Storing a Custom Digital Modulation State on page 341, then preset the signal generator to clear the
stored user–defined, digital modulation waveform from volatile ARB memory.
Figure 13-21 Recalling a Custom Digital Modulation State
1. In the Quick Setup menu, press Custom Digital Mod State.
2. Highlight the desired file (for example, NADCQPSK).
3. Press Select File > Return.
4. Press Digital Modulation Off On until On is highlighted.
The instrument regenerates the custom, digital modulation waveform in volatile memory. After
waveform generation, the custom, digital modulation waveform is available to be modulated on the
RF output.
For instruction on configuring the RF output, see Configuring the RF Output on page 338.
