Making a Measurement

7.Set the marker.

You can place a diamond-shaped marker on the signal peak to find the signal’s frequency and amplitude.

To activate a marker, press the m key (located in the MARKER section of the front panel). The MARKER NORMAL label appears in inverse video to show that the marker is the active function. Turn the knob to place the marker at the signal peak.

You can also use the CPEAK SEARCH] key, which automatically places a marker at the highest point on the trace.

Readouts of marker amplitude and frequency appear in the active function block and in the upper-right corner of the display. Look at the marker readout to determine the amplitude of the signal.

If another function is activated, the frequency and amplitude can still be identified by looking at the marker readout in the upper-right corner of the screen.
