Custom Digital Modulation (Option 431)Using the Arbitrary Waveform GeneratorSelecting the Filter1. In the Setup Mod menu (page 271), press Filter > Select > Nyquist.2. Press Return > Return.Generating the WaveformPress Digital Modulation Off On.This generates a waveform with the custom, single–carrier NADC, digital modulation state created inthe previous sections. The display changes to Dig Mod Setup: NADC (Modified). During waveformgeneration, the DIGMOD and I/Q annunciators appear and the custom single–carrier digitalmodulation state is stored in volatile memory. The waveform is now modulating the RF carrier.For instructions on storing this custom, single–carrier NADC, digital modulation state to thenon–volatile memory catalog, see Storing a Custom TDMA Digital Modulation State on page 273.Configuring the RF Output1. Set the RF output frequency to 835 MHz.2. Set the output amplitude to 0 dBm.3. Press RF On/Off.The user–defined NADC signal is now available at the RF OUTPUT connector.Storing a Custom TDMA Digital Modulation StateUsing this procedure, you learn how to store a custom digital modulation state and a custommulticarrier digital modulation state to non–volatile memory.If you have not created a custom, single–carrier, digital modulation state, complete the steps in theprevious section, Creating a Custom TDMA Digital Modulation State on page 271.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 273
