Query Syntax

:JOBS:RESults:INFO:AENGine? <Job ID>

Where <Job ID> is an integer that represents the Job ID.

Query Response

Returns an integer that identifies the acquisition engine number or -1 if the Job ID is not valid.

{1:16 | -1}

Description

For the specified Job ID, returns the ID of the acquisition engine used to control the hardware. An acquisition engine is defined to be a combination of an N109x-series DCA-M acquisition module triggered from an N107x-series clock data recovery module or, if available, triggered from its own internal clock recovery as is the case for an N1092B.

Up to 16 acquisition engines can be defined, although it is unlikely you will use that many. The following figure show a Hardware Diagram that has three acquisition engines. After the test program is run, this query will show that some of the Job IDs were assigned to acquisition engine 1, some assigned to acquisition engine 2, and some assigned to acquisition engine 3. This query returns the acquisition number for the Job ID, which in this example is 1, 2, or 3.

How do you know which DCA-M modules (acquisition engine) is assigned to a given Job ID? Use the following queries to identify the DCA-M modules for the Job ID:

• Acquisition module: :JOBS:RESults:INFO:AMODule?. The query returns the N109x-series DCA-M's model number, serial number, and installed options.
• Clock Recovery module::JOBS:RESults:INFO:CMODule?. The query returns the N107x-series DCA-M's model number, serial number, and installed options.

This query returns a -1 if the Job ID is not valid.
