Frequency Counter at Marker

Available in SA Mode ONLY. Use any existing marker to make highly-accurate
frequency counter readings. For highest accuracy, lock the FieldFox to a stable
external frequency reference. Learn how on page 181.
When Frequency Counter is ON, the FieldFox uses background sweeps to zoom
on the signal, measure the signal peak with 1 Hz resolution, and display the
frequency of the signal peak in the marker annotation area. The marker does not
move to the signal peak.
When Freq Counter is ON, measurement sweeps are considerably slower.
How to use Frequency Counter
 Press Marker .
 Press Normal, Delta, or Peak, or select an existing marker to use as a frequency
 Locate the marker somewhere on a CW signal. It does NOT have to be on the

Audio Beep at Marker Power

When enabled, the Audio Beep feature emits a repetitive beep sound which
varies in tone pitch and repetition rate to indicate the relative power level of the
active marker. The highest tone pitch and fastest beep rate occurs when the
marker Y-axis position is at the top of the display. Conversely, the lowest pitch
and repetition rate occurs at the bottom of the display. Therefore, it is important
to scale the signals that you intend to measure between the top and bottom of the
screen. Learn more about Scale on page 80.
Audio Beep can be used with any marker type or function, including
Band/Interval Power. Learn more on page 104.
