Center Freq
This field sets the tune frequency for the center of the screen.
Operating Considerations
This field also changes the frequency of the Tracking Generator’s and the RF
Analyzer’s center frequency.
Ref Level
Reference level sets the amplitude reference level for the top line of the display.
All signals displayed are referenced to this line.
Operating Considerations
The unit-of-measure for the reference can be changed as needed. For instance, 0
dBm, 0.224 V, 107.0 dB mV, and 0.00100 W can all be used to represent the same
level.
