Measuring Frequency and Power in the Spectrum Display

To measure the frequency and power at a point on a Spectrum trace:
1. Select Markers > Define Markers.
2. Select the Marker Properties tab.
3. Click Add. This displays a drop-down list under MR (Marker Reference), found inside the Reference
box. The first marker defined is always designated the Marker Reference. Subsequently defined
markers are designated as Delta Markers (you can also select and adjust markers by clicking on an
existing marker on a trace).
4. From the drop-down list, select the trace to which you want to assign the marker.
5. Click the close control panel button to remove the Define Markers control panel.
6. Click on the marker on the trace to activate that marker.
7. Use the knob or the arrow keys on the front panel to move the marker to the desired location on the
trace. You can also click on the marker location text box in the Markers toolbar at the bottom of the
screen and adjust it with your mouse wheel. The Peak button in the Markers toolbar and the arrow
buttons to the right of it control marker peak searching on the trace.
8. Read the frequency and power level of the marker position on the display.
9. Read the signal density, frequency and power level of the marker position on the display.
