The Data Mode parameter controls how often the 89600 VSA commands the Logic Analyzer application to run (in order to get new measurement data). It only applies to online measurements. If the Logic Analyzer application is offline, the behavior is identical to Continuous mode, except that no run command is ever issued.

Note: Use Block Mode to make triggered measurements with the VSA.

If the 89600 VSA Data Mode is Continuous, the VSA commands the Logic Analyzer to run a single measurement, then takes the data needed for one VSA measurement from the Logic Analyzer buffer. If there is sufficient unused data in the buffer, then the VSA takes data for succeeding measurements by moving through the Logic Analyzer buffer, until the data is exhausted.

If the 89600 VSA Data Mode is Block, the VSA commands the Logic Analyzer to run before every VSA measurement. If the 89600 VSA s set to block mode with a free run trigger, avoid setting the acquisition depth much larger than needed for a measurement because it slows down the measurement. If the 89600 VSA is set to block mode with an external trigger, the correct acquisition depth selection depends on the Logic Analyzer Trigger Position and the amount of pre- or post-trigger delay and the time record length set on the 89600 VSA
