As shown, some of these list items have additional sub-lists. Clicking on it opens a sub-list displaying the many Bluetooth sequence steps available. For example, as shown in Figure 2, when configured to test a Bluetooth device, a sequence step labeled Bluetooth appears in the list. In some cases, an item in the list of sequence steps has a dark triangle on the right, indicating the presence of a sub-list. It can be used to set the on/off state and the DC voltage of the PDM module’s Vdd power supply at any point in the test sequence. This step is only present for analyzers equipped with a PDM Module. For example, in Figure 1c, there is a step labeled “Set Vdd Output…”. This list is context-sensitive, meaning the steps available will change depending on the specific APx model in use, which digital IO modules are installed, and which input and output connectors are selected. The Sequence Steps node in the Level and Gain measurement.Ĭlicking the node with the plus sign icon labeled “Add Step…” will display a list of sequence steps that can be added to the current measurement, as shown in Figure 1c. These steps will be executed only if their checkbox is checked.įigure 1.

Other Sequence Steps usually have a checkbox, like the Turn Generator On step in Figure 1b. This node represents the point in the sequence when the selected measurement will be run. The list always includes a step with a triangular “play” icon – for example, the Measure Level and Gain step in Figure 1b. Clicking on this node will expand it to reveal one or more Sequence Steps (Figure 1b). One of the most useful features of Sequence Mode is one that new or casual APx users may not yet have discovered: Sequence Steps.Įvery measurement in the APx software has a node with a folder icon labeled Sequence Steps, which is collapsed by default to reduce UI clutter (Figure 1a).

With its built-in test sequencer, reporting engine, test limits and pass/fail indicators, Sequence Mode in the APx500 software can be very useful for repetitive audio tests in R&D, product verification and production test applications.
