M9393A List Mode; List Mode Set Up - Keysight Technologies M9393A Programming Manual

M9393A List Mode

Use the "List" Mode to record a set of IVI commands that can be quickly executed
on the M9393A hardware. In the List Mode, IVI commands are recorded as a binary
stream and are played back using the FPGA component of the M9214A PXIe
Digitizer. Thus, the execution speed for such a binary stream is much faster than if
the commands were to be executed sequentially by the host controller.
List Mode is useful in automated manufacturing situations where making high
speed signal acquisitions with accurate timing is important to reduce test times for
a device under test (DUT). By reducing the test times, increased production
throughput is achieved.

List Mode Set Up

Using IVI methods and properties, you can create and play one or more named List
that can be cataloged in the M9393A driver. A List executes a predefined set of
Acquisitions, each of which starts with the specified
specific configurations, such as sample rate, offset, and frequency. There are
several different
list mode, there is another acquisition trigger mode called
Scheduler makes it possible to make a series of acquisitions with accurate timing
using the internal timer. The List can also generate outgoing triggers. Using proper
acquisition triggers and outgoing triggers, the List can interact with DUT and other
external equipment as well as control the timing of acquisitions autonomously with
the internal timer. This enables you to perform complicated test sequences.
