Custom Arb Waveform Generator
Working with
Customizing a Multicarrier Setup
In this procedure, you learn how to customize a predefined multicarrier digital modulation setup by creating a custom
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
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 file name from the Catalog of MDMOD Files occupying the active entry area, press Edit Keys > Clear Text.
12.Enter a file name (for example, EDGEM1) using the alpha keys and the numeric keypad, and press Enter. The
