Item Element Description
1
Check mark indicator 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.
2 Top of Graph Sets the phase 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.
3 Position Speci fi es the phase value shown at the center of the graph display.
4 Bottom Readout Displays the value of the phase value shown at the bottom of graph.
5 Autoscale Adjusts the vertical and horizontal settings to provide the best display.
6 Position Displays the horizontal position of the trace on the graph display.
7 Scale Adjusts the span of the graph in symbols.
8 Freq Error 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).
