Audio Precision ATS-1 Access - External Connections; Analog Inputs and Outputs

External Connections
How a device is set up for testing depends on the type and function of
the device.
Analog Inputs and Outputs
Electrical connections between a device under test and the test
instrument are typically made with test cables. Analog test cables for
the ATS-1 Access should have appropriate connectors on both ends
for connection to the test instrument. Adapters may be used to adapt
a standard cable to the device or test instrument.
When cables or adapters for unbalanced connectors are used with an
XLR connector panel, pin 2 of the XLR connector should connect to
the signal conductor and pin 3 of the XLR connector should connect to
the ground. Also be sure to select an unbalanced generator
configuration (see page 3-29).
The ATS-1 Access’ Generator Outputs should be connected to the
analog inputs of the device under test. The Analyzer Inputs should be
connected to the analog outputs of the device under test.
