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 numerical 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
