Input gain range settings are also available as menu choices from within the
applications that make measurements on analog signals. From within a running
application, you can make the change and observe the effects on the signal.
Digital Input Connector Selection. The Digital Main Input connector selection choices
are: Front-panel XLR connector (the most common selection and made by default),
the Rear-panel BNC, and the Rear-panel Optical connector. An internal connection
to the AES generator is also available. Touching the selection soft key associated
with the digital generator choices advances the selection box through the list.
Measurement Channel Assignment. A pull-down menu (see Figure 3-5) is used to
individually assign the signal to the two measurement channels of the AM700. The
same input signals choices are available for both Channel 1 and Channel 2, and the
channels can have the same signal applied to each as well. If you want both inputs
to be obtained from the same type of generator (High Resolution, High Bandwidth,
or Digital Main), the fast selection soft keys along the lower right of the screen can
be used (see Figure 3-5). With a single touch of the choice, both measurement
channels can be set simultaneously to the A and B High Resolution generator, the A
and B High Bandwidth generator, or the Digital Main Inputs. (The measurement
channel assignment choices are also available in the application Main menus using
the Input menu.)
