Description
The check mark indicator in the upper, left-hand corner of the display shows
when the Frequency Deviation vs Time display is the optimized display.
Sets the frequency deviation value indicated at the top of the graph. Changing
the top value affects the bottom of graph readout. Also, note that the top of
graph setting interacts with the internal vertical scale setting (which is not
user settable) such that the range between the top and bottom of the graph
increases or decreases automatically.
Specifies the frequency deviation value shown at the center of the graph
display.
Displays the value of the frequency deviation value shown at the bottom
of graph.
Adjusts the vertical and horizontal settings to provide the best display.
Specifies the horizontal position of the trace on the graph display.
Adjusts the span of the graph. By decreasing the scale (time per division), the
graph essentially becomes a window that you can move over the acquisition
record by adjusting the offset.
Displays the difference between the maximum and minimum measured
values of the signal frequency during the Measurement Time. The displayed
frequency error is followed by either Auto or Manual. This indicates the
selected carrier frequency detection method (see Settings > Freq & BW).
