To Apply Bit Errors to an Existing Data Pattern User File

This example demonstrates how to apply bit errors to an existing data pattern user file. If you have not created and stored a data pattern user file, first complete the steps in the previous section, “Creating a Data Pattern User File with the Bit File Editor” on page 149.

1.Press Apply Bit Errors.

2.Press Bit Errors > 5 > Enter.

3.Press Apply Bit Errors.

Notice both Bit Errors softkeys change value as they are linked.

Using an Externally Supplied Data Pattern

In this procedure, an external real time data pattern is supplied through DATA, DATA CLOCK, and SYMBOL SYNC connectors.

1.Press Preset.

2.Press Mode > Custom > Real Time I/Q Baseband > Data > Ext.

3.Connect the real-time data to the DATA input.

4.Connect the data clock trigger signal to DATA CLOCK input.

5.Connect the symbol sync trigger to the SYMBOL SYNC input.
