Setting Up the Instrument
7
Set the Bit Rate
Now we want to set the pattern generator's bit rate. For now, we will use the
instrument's internal clock:
Switch to the
Bit Rate Setup.
Select the
Internal
Clock Source.
Enter the required
clock rate or select
one of the presets
from the list.
You can also define
your own entries.

Now select the data pattern
to be used for the test:
Select the Pattern
Press the
Pattern Setup
button to switch to the
pattern editor.
Open the
Pattern
Select
dialog box.
Select the pattern
type
2^n-1 PRBS.
Select the pattern
size
2^31-1.
The cable does not convert any data.
Therefore, we use the same pattern
for the pattern generator and the
error detector.
Besides generated patterns like PRBS, you can also use memory-based
patterns. A large variety of useful test patterns is already provided, but
you can also set up your own custom patterns. See the Help for details.
