Setting Up a Repetitive Burst Signal

Task S et 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:

1Disable the outputs.

2In the instrument panel, choose the RBurst mode.

3Enter 4 for the number of null data packets.

4Define that the number of zeros t hat follows the repeated bursts is

as large as the burst length.

5Set the frequency to 100 MHz.
