2.1.8 Y Axis Units
Displays the menu keys that enable you to change the vertical (Y) axis amplitude units.
The analyzer retains the entered
Y Axis Units separately for both Log and Lin amplitude
scale types. For example, if
Scale Type has been set to Log, and you set Y Axis Units to dBm,
pressing
Scale Type (Log) sets the Y Axis Units to dBm. If Scale Type has been set to Lin and
you set
Y Axis Units to Volts, pressing Scale Type (Lin) sets the Y Axis Units to Volts. Pressing
Scale Type (Log) again sets the Y Axis units back to dBm.
This key is unavailable (grayed out) when the FM Demod View is on.
Y Axis Units, in conjunction with the Scale Type, affect how the data is read off the display,
markers, and over the remote interface. When using the remote interface no units are
returned, so you must know what the Y-Axis units are to interpret the results:
