Setting Up a Repetitive Burst

Signal

Task Set up a signal with 4 repeated bursts.

Each burst consists of a 32- bit pattern signal with NRZ data

output format at 100 MHz to check a digital circuit with LVPECL

logic.

The data pattern is:

11100000000000000000000000000000

Using the Graphical User Interface

Instrument Settings To set the instrument parameters:

1 Disable the outputs.

2 In the instrument panel, choose the RBurst mode.

3 Enter 4 for the number of null data packets.

4 Define that the number of zeros that follows the repeated bursts

is as large as the burst length.

5 Set the frequency to 100 MHz.
