5. With Freq Count ON, you can scroll through the existing markers that are
located on a discrete CW signal, and read the frequency of the signal
peak. However, each frequency count update requires another sweep. If
the FieldFox is in HOLD, press Single to update the frequency count
results.
Time Zero Fixed Marker
This feature was created to allow recall of vintage instrument states (older than
Rev. 7.0) that included Zero span sweep with a trigger delay and at least one
marker. Before Rev. 7.0, these instrument states were saved and recalled with
the equivalent of the ON state of this setting. The default setting is OFF. Learn
more about Triggering with negative delay in
“Triggering” on page 197.
1. Press Mkr->/Tools > More > Mkr Properties > Time Zero Fixed
2. Then choose from the following:
—
ON Time Zero is fixed at the left-edge of the screen. A marker in
negative delay resides at this point. This is the vintage behavior.
—
OFF (default) Time Zero is located at the T-zero indicators. A marker
in negative delay appears to the left of T-zero.
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 in
“Scale and Units” on
page 159
.
Audio Beep can be used with any marker type or function, including
Band/Interval Power. Learn more in “Audio” on page 786.
