3. Choose the Timing Mode option.
You can also select the timing sampling mode in the "Pod Assignment
Dialog" on page 130.
To select the full/half channel configuration
1. In the Sampling tab, with Timing Mode selected, select the timing analyzer
configuration. You can choose between:
• 8M Sample Full Channel 333 MHz
NOTE:
When the Sample Period is 3.0 ns, data is acquired at two times the trigger
sequencer rate. This means that data must be present for at least two samples
before the trigger sequencer can reliably detect it. The trigger sequencer
could miss data present for less than two sample periods.
The trigger sequencer treats the data as a group of two samples for each
sequencer clock. This means that the trigger point indication could be off by
one sample.
Although the trigger sequencer cannot detect all data, the analyzer will
correctly capture all data present for at least one sample period.
• 16M Sample Half Channel 667 MHz

In this configuration, the total memory depth is 8M samples per
channel, with data being sampled and stored as often as every 3.0 ns.
You can set the sample rate to go slower with the Sample Period
control.
In this configuration, only one pod of each pod pair is available.
Channels assigned to unavailable pods are ignored. You can specify
which pod to use by toggling the Pod field in Format.
The total memory depth is 16M samples per channel. Data is sampled
and stored every 1.5 ns; this rate cannot be changed.
