Custom Real Time I/Q Baseband

Configuring Hardware

8.Press Enter.

The contents of the current Rise Shape and Fall Shape editors are stored to the Catalog of SHAPE Files. This burst shape can now be used to customize a modulation or as a basis for a new burst shape design.

To Select and Recall a User-Defined Burst Shape Curve from the Memory Catalog

Once a user- defined burst shape file is stored in the Memory Catalog, it can be recalled for use with real- time I/Q baseband generated digital modulation.

This example requires a user- defined burst shape file stored in memory. If you have not created and stored a user- defined burst shape file, complete the steps in the previous sections.

1. Press Preset.

2. Press Mode > Custom > Real Time I/Q Baseband > Burst Shape > Burst Shape Type > User File.

3.Highlight the desired burst shape file (for example, NEWBURST).

4.Press Select File.

The selected burst shape file is now applied to the current real- time I/Q baseband digital modulation state.

5.Press Return > Custom Off On.

This generates the custom modulation with user- defined burst shape created in the previous steps. During waveform generation, the CUSTOM and I/Q annunciators activate. The waveform is now modulating the RF carrier.

6.Press RF On/Off.

The current real- time I/Q baseband digital modulation format with user- defined burst shape should be available at the signal generator’s RF OUTPUT connector.
