Page 6: Preparing The Test
Preparing the Test How Can You Check the Instrument’s Operation? The quickest way to familiarize yourself with the instrument is to set up a short test. All you need for this test is an oscilloscope or Digital Communication Analyzer, two APC/RPC cables, and maybe two SMA adapters to connect the pattern generator’s Data Out and Clock Out to the oscilloscope. - Page 7 Preparing the Test Setting up Voltage Levels Switch to the PG Output Setup Now select the logic family LVDS for the data and clock port. Let's increase the signal's data offset by 100 mV. Just tip the offset field, and turn the fine-tuning knob until you have the desired value.
- Page 8 Viewing the Eye Diagramm We will now generate a Pseudo Random Binary Signal (PRBS) and observe the eye diagram with the oscilloscope. Choose the Pattern Press the Pattern Select button to open the Select Pattern dialog. Select the pattern type 2^n –1 PRBS.
- Page 9 Setting up a Sequence of Patterns The built-in sequencer allows you to define sequences of patterns. A sequence consists of up to four blocks that can be looped. Each block can generate a pause signal (constant 0 or 1), a divided clock, a 2^n –1 PRBS, or a user pattern.
- Page 10 Modifying the Test Setup Inserting Data into the Sequence Blocks Click the Edit... button inside the first block. Click Pattern and browse for the header pattern you have stored. Click the Edit... button of the second block. Set the length to 2048 bits and click PRBS Select the polynomial you wish to generate.

Page 11: Viewing The Results
Inspecting the Sequence Execution To observe the sequence trigger together with the generated data, you need a two-channel oscilloscope that can synchronize on the signal at a channel. If your oscilloscope requires a separate trigger, you need a power splitter and two additional cables to connect the instrument’s Trigger Out with the second channel and the trigger input of the scope. -

What Else You Can Do Generate Trigger Signals The pattern generator can be set up to send trigger signals for different purposes. These signals can indicate various occasions like the beginning of patterns. Use Alternating Patterns Set up two different data patterns that are sent alternately or externally controlled.
