8.5 SPECTRUM
Narda FieldMan 79
8.5.2 Measuring and evaluating a spectrum
8.5.3 Numerical display
The measurement starts immediately after selecting the operating mode.
The ◄ ► keys can be used to move and evaluate the marker at any time during the mea-
surement. However, to use the peak marker, the display must be stopped.
Stop and start measurement:
⇒ Press SK3.
In the graphical display, the measured values can be evaluated using the Peak Marker
function (see 8.5.4 Graphic display on page 81).
Two fields are available for numer
ical display:
• Main field: Displays current or statistical broadband values depending on the
selected result type and detection type
• Supplementary field: Always displays statistical broadband values
Detector
A selection is only available for the BFD-400-1 probe. For all other probes, RMS is spec-
ified.
Select a detector:
⇒ MEASUREMENT SETTINGS: Select a detector under Detector.
Detector Description Availability
RMS All measured values are recorded and displayed
as RMS values.
All probes
Peak All measured values are recorded and displayed
as peak values.

Result type
In SPECTRUM mode, the control pad is used for the marker. The selection of the result
type is therefore made in the measurement settings.
Select a result type:
⇒ MEASUREMENT SETTINGS: Select the desired result type under Result Type.
↳ The selection option depends on the detector and the probe.
