SOURce:DAUDio Subsystem
3–108 AM700 Audio Measurement Set Programmer Manual
SOURce:DAUDio Subsystem
SOURce is the root command in the SOURce Subsystem for the AM700. The
SOURce setup commands are divided into several sections. Each section or
subsystem deals with controls that directly affect device-specific settings of the
AM700; not those related to the signal-oriented characteristics. These
commands are referenced through the SOURce node.
Suffixes: SOURce5 is digital generator chan A
SOURce6 is digital generator chan B
SOURce7 is DSP chan A
SOURce8 is DSP chan B
The special commands under DAUDio are used to control the operation of the
digital audio signal generator. See GCONtrol for additional commands
controlling the audio generator, and OUTPut for commands that control the
digital interface parameters.
The special commands under AUDio select the sample rate and word size of the
digital audio signal. Also, the shape of the applied dither may be selected as
either rectangular or triangular.

SOURce[5–8]:DAUDio:AUDio:SRATe HIGH|MEDium|LOW

Usage: Selects the sample rate used for the digital audio signal from the generator.
Parameters: HIGH = 48 kHz
MEDium = 44.1 kHz
LOW = 32 kHz.
Query: SOUR[5–8]:DAUD:AUD:SRAT? returns the identifier for the currently
assigned audio sample rate.
Current software in the AM700 forces both channels on a digital interface to
have the same sample rate. Changes to one channel will then cause the same
change in the other channel.
*RST: Sets SRATe to HIGH.
