AM700 Audio Measurement Set User Manual
System Setup. Touch this soft key to display the System Setup menu. Soft keys in
this display allow you to set the date and time, configure the serial and GPIB
communications parameters, select copy format and destination for display captures,
activate calibration, and specify the external input and output resistance values to be
used for units conversions between volts, dBu, and dBm, and to specify the
conversion factor to dBFS.
View Setup. Touch this soft key to display the View Setup menu. Here is where you
select the measurements to be displayed and the type of view in which the selected
measurement is displayed. In this menu you can also touch the View Options soft
key to display a menu where you can configure the type of display axes and
waveform, whether cursors are enabled (turned on or not), and whether the cursors
will be constrained to the trace data (Snap to Data) or will permitted to be
positioned anywhere in the display window.
System Status. Touch this soft key to display a summary of the AM700 system
configuration selections as seen in Figure 2-12 on page 2-19. This display is useful
for quickly determining what measurement the views in the running application are
set up to display, how the trace data is displayed (interpolator, point plot, or tabular),
the measurement channel input selection, and the generator signal type choices for
the analog and digital generators.
State Saving. This selection provides two choices: one saves the present state of
instrument settings that can be saved, and the other restores the factory default
settings. If you want to save a particular setup state for an application, it should be
done immediately before turning off the AM700. Settings for many of the controls
are saved each time an application is changed. Any settings that are saved when
State Save is used are overwritten if further changes are made and another
application is started prior to power off. State Save does not return the application
that was running at power off when power is again turned on, but the user selections
for an application that were saved will be restored.
Also, refer to the Save AM700 State function discussion on page 4-136. The Save
AM700 State function generates new functions that store customized application
setups. These application setup functions are then used in making repetitive tests
and for building a standardized set of application setups that can be transferred to
other AM700 Audio Measurement Sets.
