Using Custom Digital Modulation for N5172B/82B with Option 431 and 653/655/656/657
Using the Arbitrary Waveform Generator
Storing a Custom Multicarrier Digital Modulation State
Using this procedure, you learn how to store a custom, multicarrier, digital modulation state to
non–volatile memory.
If you have not created a custom, multicarrier, digital modulation state, complete the steps in the
previous section, “Creating a Custom Multicarrier Digital Modulation State” on page 288.
Figure 9-30 Storing a Custom Multicarrier Softkeys
1. Return to the top–level Digital Modulation menu, where Digital Modulation Off On is the first
softkey.
2. Press Multicarrier Setup > More > Load/ Store > Store To File.
If there is already a file name from the Catalog of MDMOD Files occupying the active entry
area, press the following key: Clear Text
3. Enter a file name (for example, EDGEM1) using the alpha keys and the numeric keypad with a
maximum length of 23 characters.
4. Press Enter.
The user–defined, multicarrier, digital modulation state is now stored in non–volatile memory.
Applying Changes to an Active Multicarrier Digital Modulation State
If the digital modulation format is currently in use (Digital Modulation Off On set to On) while
changes are made in the Multicarrier Setup table editor, you must apply the changes before
the updated waveform will be generated.
From the Multicarrier Setup table editor, press Apply Multicarrier to apply the changes and
generate a new custom multicarrier digital modulation waveform based on the updated values.
The RF output amplitude, frequency, and operating state settings are not
stored as part of a user–defined, digital modulation state file.

Fixed: All the carriers are set to a
phase of 0.
Random: All of the carriers are
set to a random phase value.
