Choosing the Sampling Mode

If all pods are used, memory depth is reduced by half in order to store the required time tags.

With the Sample Period at 2.5 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.

To specify the sample period

When the logic analyzer is in timing (asynchronous sampling) mode, the Sample Period setting specifies how often the logic analyzer samples the signals from the device under test.

1.In the Sampling tab, with Timing Mode selected, enter the desired time between logic analyzer samples.

To capture signal level changes reliably, the sample period should be less than half (many engineers prefer one-fourth) of the period of the fastest signal you want to measure.

The sample rate is the inverse of the sample period.

In the conventional timing configuration, the sample rate is fixed at 1.25 ns.
