Setting Up the Proper Configurations
Setting Up the Proper Configurations
This section discusses setting up the configuration attributes and
parameters of the pattern generator.
If you are reloading existing configurations or downloading ASCII
vector files, refer to the Load operation in the disk drive menus of the
System.

To set up the configuration

1From the Format menu, set the Vector Output Mode to either
full- or half-channel.
Make this selection first because clock frequencies and available
channels are affected.
In half-channel mode, only pods 1 and 3 are used.
2Set the Clock Source to either internal or external.
An external clock is used when you need a clock frequency that is not
available internally, or if you need to drive the pattern generator timing
with an external reference.
3Set the Clock Period for an internal clock or the Clock Frequency
for an external clock.
The external clock frequency information is required to select the
appropriate operating mode. Operating the pattern generator at an
external clock frequency higher than selected will result in erroneous
operation.
