Custom Digital Modulation (Option 431)
Using the Arbitrary Waveform Generator
Selecting the Filter
1. In the Setup Mod menu ( page 380 ), press Filter > Select > Nyquist .
2. Press Return > Return .
Generating the Waveform
Press Digital Modulation Off On .
This generates a waveform with the custom, single–carrier NADC, digital modulation state created
in the previous sections. The display changes to
Dig Mod Setup: NADC (Modified)
. During
waveform generation, the
DIGMOD
and
I/Q
annunciators appear and the custom single–carrier
digital modulation 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 the non–
volatile memory catalog, see Storing a Custom Digital Modulation State on page 382.
Configuring the RF Output
1. 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 Digital Modulation State
Using this procedure, you learn how to store a custom digital modulation state and a custom
multicarrier digital modulation state to non–volatile memory.
If you have not created a custom, single–carrier, digital modulation state, complete the steps in the
previous section, Creating a Custom Digital Modulation State on page 380.
