      Audio Adapter for Analog Discovery SKU: 410-405   Product Description   The Audio Adapter for Analog Discovery provides an easy method of connection to analyze audio signals with the Analog Discovery oscilloscope instrument. It is equipped with one Mono and one Mono/Stereo Jack connector connected to the inputs of the oscilloscope and a 2x15 MTE connector to pass through all other signals. The Audio Adapter is compatible with Analog Discovery Legacy and Analog Discovery 2. Features:        One 3.5 mm Mono Audio Jack connector One 3.5 mm Stereo Audio Jack connector 2 Mono vs 1 Stereo Selection Jumper Pass through Connector for the Digital I/O Signals, Power Supplies, and Triggers Compatible with the Analog Discovery 2 and Analog Discovery (Legacy) What's Included:       Audio Adapter for Analog Discovery Custom Anti‐Static Packaging  Analog Discovery Audio Adapter Reference Manual The Analog Discovery Audio Adapter is a module that allows analyzing audio signals from external sources or from the Analog Discovery audio jack socket. It is equipped with a Mono and a Mono/Stereo Jack connector that are connected to the inputs of the oscilloscope. The Audio Adapter is equipped with the 2×15 Analog Discovery connector, which makes it compatible with Analog Discovery Legacy and Analog Discovery 2. An additional 2×15 Analog Discovery connector is loaded as a pass through for the digital signals that can be further used for other applications.  Overview Features     Mono and Mono/Stereo Jack connectors Selection Jumper Pass through Connector for the Digital I/O Signals Compatible with the Analog Discovery 2 and Analog Discovery (Legacy) Compatible Products The Analog Discovery Audio Adapter is compatible with the following:   Analog Discovery 2 Analog Discovery (Legacy) About this Document This reference manual applies to Revision B of the Analog Discovery Audio Adapter. Functional Description Connectors and Jumpers Label Name  Description  J1  2×15 Analog Discovery  connector  Interfaces the Audio Adapter with the Analog Discovery  J2  2×15 Analog Discovery  connector  Used for passing through the unused signals of the Analog  Discovery  J3  Mono/Stereo Jack  connector  Used to connect a mono or a stereo audio source to the inputs of  the Analog Discovery scope  J4  Mono Jack connector  Used to connect a mono audio source to the inputs of the Analog  Discovery scope  JP1  Mono/Stereo Selection  Jumper  Used to select if through J3 will pass a mono or stereo signal  Visualizing the Audio Signals The Analog Discovery Audio Adapter is used to analyze the audio signals taken from an external source or from the Analog Discovery. It uses the Oscilloscope device instrument. If the audio signals are generated by the Analog Discovery, a 3.5mm male jack stereo cable needs to be connected to the stereo input of the audio adapter. The Wavegen of the Analog Discovery is not directly connected to the adapter. The adapter can process stereo audio signals from the Analog Discovery or from external sources. It can also be used for analyzing mono audio signals fro external sources. The Mono and Mono/Stereo measuring functions are implemented as in the circuits below: Mono/Stereo connector (J3) can be used to see mono or stereo inputs. In order to select the mode for the oscilloscope, JP1 should be placed in the desired mode. Stereo Mode In stereo mode the signals from the connector are routed to Scope1+ and Scope2+ of the Analog Discovery. Scope1- and Scope2- are connected to the ground. In this mode, each audio channel corresponds to a scope channel. Mono Mode By selecting the mode Mono on JP1, the audio channel will be routed to Scope1+. As the Jack connector is stereo, the second signal contact will be connected to the ground. Mono connector (J4) can be used to see mono inputs. Paired with the Mono/Stereo connector in Mono mode, gives access to two individual mono channels. The audio channel is routed to Scope2+. Warning: Please be careful when connecting a stereo audio source into the mono connectors as it will short the second channel to ground. This may lead to damaging your audio equipment if it's not protected. Power The device doesn't require any external power supply. Software Support The Analog Discovery Audio Adapter is controlled with the Analog Discovery through the use of WaveForms. Additional Information   WaveForms can be downloaded from the WaveForms Resource Center.
