About SA Application

Description

Set and read the sweep order. This command applies whenever frequency and power are being swept (sweep type set using the SourceSweepType2 command). Otherwise, this setting is ignored. For example, if all the active sources are set to CW and/or linear sweep type, or if all the active sources are set to CW and/or power sweep type, the sweep order is ignored. If any active source is set to linear and power sweep type, or if an active source is set to linear sweep type and another active source is set to power sweep type, then the sweep order setting will be used.
