Working with User-Defined Setups (Modes)−Custom Arb Only

Modifying a Single-Carrier NADC Setup

In this procedure, you learn how to start with a single-carrier NADC digital modulation and modify it to a custom waveform with customized modulation type, symbol rate, and filtering.

1.Press Preset.

2.Press Mode > Custom > ARB Waveform Generator > Setup Select > NADC.

3.Press Digital Mod Define > Modulation Type > PSK > QPSK and OQPSK > QPSK.

4.Press Symbol Rate > 56 > ksps.

5.Press Filter > Select > Nyquist.

6.Press Return > Return > Digital Modulation Off On.

This generates a waveform with the custom single-carrier NADC digital modulation state. 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.

7.Set the RF output frequency to 835 MHz.

8.Set the output amplitude to 0 dBm.

9.Press RF On/Off.

The user-defined NADC signal is now available at the RF OUTPUT connector.

10.Press Return > Return.

This returns to the top-level Digital Modulation menu, where Digital Modulation Off On is the first softkey.

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.
