Custom Digital Modulation (Option 431)Using the Arbitrary Waveform GeneratorRecalling a Custom TDMA Digital Modulation StateUsing this procedure, you will learn how to recall a custom digital modulation state from signalnon–volatile memory.If you have not created and stored a user- defined, single–carrier, digital modulation state, completethe steps in the previous sections, Creating a Custom TDMA Digital Modulation State on page 271and Storing a Custom TDMA Digital Modulation State on page 273, then preset the signal generatorto clear the stored user–defined, digital modulation waveform from volatile ARB memory.Figure 11-9 Recalling a Custom TDMA Digital Modulation StateMode > ARB Custom Modulation > Single Carrier Setup >For details on each key, use keyhelp as described on page 42.Loads the highlighted fileinto the instrumentmemory.These keys manage the tableof DMOD files in internalstorage.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. Afterwaveform generation, the custom, digital modulation waveform is available to be modulated on theRF output.For instruction on configuring the RF output, see Configuring the RF Output on page 270.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 275
