AM700 Audio Measurement Set User Manual
The choices in the Axes column allow the linear/log selection for the x- and y-axes
and a choice of Dual Y-Axis. Dual Y-Axis displays are permitted when more than
one trace is displayed in a single view. In Dual Y-Axis displays, the vertical or
y-axis scale of the front trace is seen on the left side of the graticule and y-axis scale
for the back trace is seen on the right side of the graticule. Other axes choices are
determined by the view type.
When persistent is enabled, trace data is accumulated and held in the display in a
continuous storage mode. This feature is very useful for gathering history on the
waveform changes and showing the bounds of varying signals in either frequency,
voltage, or both. Turning persistent off restores the trace to showing trace data for a
single acquisition only.
Cursor controls for enabling the cursors and holding the cursors to the displayed
data are found in the Cursors column. Enabling or disabling cursors is the same as
turning them on or off using the Cursor button on the front panel. Selecting Snap to
Data is used to hold the cursors on actual data points in the trace display.
NOTE. When cursors are viewed on a Dual Y-Axis display, they are associated only
with the front trace. The amplitude readouts accompanying the cursors reflect the
amplitude at the cursor positions in the front trace.
Saving Changes and Exiting the Input Selections Menu. Soft keys to exit the input
selection menu are located at the bottom of the screen. When the Accept Changes
soft key is touched, any selections made are entered. If the Cancel soft key is
touched, all changes are deleted before returning to the current application. Pressing
the Clear Menu button also exits back to the application.
