Measuring Multiple Signals
This section provides the information on how to measure
multiple signals.
Comparing Signals on the Same Screen Using Marker Delta
The delta marker function allows the user to compare two
signals when both appear on the screen at the same time.
In the following example, harmonics of the 10 MHz reference
signal available are used to measure frequency and
amplitude differences between two signals on the same
screen. Delta marker is used to demonstrate this
comparison.
1
Preset the analyzer:
Press
Preset
(With
Preset Type
of
Factory
)
2
Connect the rear panel
REF OUT
to the front panel
RF IN
.
3
Set the analyzer center frequency, span and reference level
to view the 10 MHz signal and its harmonics up to 50 MHz:
Press
Frequency > 30 > MHz
Press
Span > 50 > MHz
Press
Ampulitude > 10 > dBm
4
Place a marker at the highest peak on the display (10 MHz):
Press
Peak Search
The marker should be on the 10 MHz reference signal. Use
the
Next Right Pk
and
Next Left Pk
softkeys to move the marker
from peak to peak.
5
Anchor the first marker and activate a second marker:
Press
Marker > Mode > Delta
The label on the first marker now reads
1R
, indicating that it
is marking the reference point.
