Custom Arb Waveform Generator

Working with Modulation Types

Modifying a Predefined FSK Modulation Type User File with the Frequency Values Editor

Using the Frequency Values editor, you can define, modify, and store user-defined frequency shift keying modulation. The Frequency Values editor is available for custom Real-Time I/Q Baseband mode, but is not available for waveforms generated in custom Arb Waveform Generator mode. Use this example to learn how to add errors to a default FSK modulation.

1.Press Preset.

2.Press Mode > Custom > Real Time I/Q Baseband > Modulation Type > Define User FSK > More (1 of 2) > Load Default FSK.

3.Press Freq Dev > 1.8 > kHz.

4.Press 4-Lvl FSK.

This sets the frequency deviation and opens the Frequency Values editor with the 4-level FSK default values displayed. The frequency value for data 0000 is highlighted.

5.Press -1.81> kHz.

6.Press -590> Hz.

7.Press 1.805 > kHz.

8.Press 610 > Hz.

As you modify the frequency deviation values, the cursor moves to the next data row. An unstored file of frequency deviation values is created for your custom 4-level FSK file.

9.Press Load/Store > Store To File.

If there is already a file name from the Catalog of FSK Files occupying the active entry area, press the following keys:

Edit Keys > Clear Text

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

11.Press Enter.

The user-defined FSK modulation should now be stored in the Catalog of FSK Files.
