Reading Frequency & Amplitude

7.Place a marker (labeled 1) on the 10 MHz peak, as shown in Figure 3-3.

Press Peak Search.

Note that the frequency and amplitude of the marker appear both in the active function block, and in the upper-right corner of the screen. You can use the knob, the arrow keys, or the softkeys in the Peak Search menu to move the marker. Pressing Esc removes the value from the display.

8.If you have moved the marker, return it to the peak of the 10 MHz signal.

Changing Reference Level

9.Press AMPLITUDE, and note that reference level (Ref Level) is now the active function. Press Marker , Mkr Ref Lvl.

Note that changing the reference level changes the amplitude value of the top graticule line.

Figure 3-4shows the relationship between center frequency and reference level. The box represents the analyzer display. Changing the center frequency changes the horizontal placement of the signal on the display. Changing the reference level changes the vertical placement of the signal on the display. Increasing the span increases the frequency range that appears horizontally across the display.
