Getting Started
Making a Measurement
When the peak of a signal does not appear on the screen, it may be necessary to adjust the amplitude level on the screen. Press @GKiKKZJ
REF LEVEL 48.8 dBmV appears in the active function block. The REF LVL softkey label appears in inverse video to indicate that reference level is the active function. The reference level is the top graticule line on the display and is set to 48.8 dBmV. Changing the value of the reference level changes the amplitude level of the top graticule line.
If desired, use the reference level function to place the signal peak on the screen using the knob, step keys, or number/units keypad. (Marker functions determine the frequency and amplitude of a signal.)
