11.Press Digital Mod Define > Store Custom Dig Mod State > Store To File.

If there is already a file name from the Catalog of DMOD Files occupying the active entry area, press: Edit Keys > Clear Text

12.Enter a file name (for example, NADCQPSK) using the alpha keys and the numeric keypad.

13.Press Enter.

The user- defined single- carrier digital modulation state should now be stored in non- volatile memory. The RF output amplitude, frequency, and operating state settings are not stored as part of a user- defined digital modulation state file.

In this procedure, you learn how to customize a predefined multicarrier digital modulation setup by creating a custom 3- carrier EDGE digital modulation state.

1.Press Preset.

2.Press Mode > Custom > Arb Waveform Generator > Multicarrier Off On.

3. Press Multicarrier Define > Initialize Table > Carrier Setup > EDGE > Done.

4.Highlight the Freq Offset value (500.000 kHz) for the carrier in row 2, and press Edit Item > −625 > kHz.

5.Highlight the Power value (0.00 dB) for the carrier in row 2, and press Edit Item > −10 > dB.

You have a custom 2- carrier EDGE waveform with a carrier at a frequency offset of −625 kHz and a power level of −10.00 dBm.

6.Press Return > Digital Modulation Off On.

This generates a waveform with the custom multicarrier EDGE state. The display changes to Dig Mod Setup: Multicarrier (Modified). During waveform generation, the DIGMOD and I/Q annunciators appear and the new custom multicarrier EDGE state is stored in volatile memory.

7.Set the RF output frequency to 890.01 MHz.

8.Set the output amplitude to −10 dBm.

9.Press RF On/Off.

The custom multicarrier EDGE waveform is available at the RF OUTPUT connector; it does not include bursting or channel coding.

10.Press Mode > Custom > Arb Waveform Generator, where Digital Modulation Off On is the first softkey.

11.Press Multicarrier Off On > Multicarrier Define > More (1 of 2) > Load/ Store > Store To File.

If there is already a area, press Edit Keys >
