Custom Arb Waveform Generator

Working with Modulation Types

6.Press More (1 of 2) > Load/Store > Store To File.

If there is already a file name from the Catalog of IQ Files occupying the active entry area, press the following keys: Editing Keys > Clear Text

7.Enter a file name (for example, NEW4QAM) using the alpha keys and the numeric keypad.

8.Press Enter. The user-defined I/Q State Map should now be stored in the Catalog of IQ Files and can be recalled even after the E8267C PSG signal generator has been turned off.

Modifying a Predefined I/Q Modulation Type (I/Q Symbols) & Simulating Magnitude Errors & Phase Errors

Use the following procedure to manipulate symbol locations which simulate magnitude and phase errors. In this example, you edit a 4QAM constellation to move one symbol closer to the origin.

1.Press Preset.

2.Press Mode > Custom > Real Time I/Q Baseband > Modulation Type > Define User I/Q > More (1 of 2) > Load Default I/Q Map > QAM > 4QAM.

This loads a default 4QAM I/Q modulation into the I/Q Values editor.

3.Press More (2 of 2).

4.In the I/Q Values editor, navigate to Data 00000000 and press Edit Item.

5.Press .235702 > Enter, then .235702 > Enter.

When you press Enter the first time, the I value updates and the highlight moves to the first Q entry. The second time, the Q value updates and the highlight moves to the following I entry.

6.Press Display I/Q Map. Note that one symbol has moved, as shown.
