Making a Basic Measurement
Valid marker count range
NOTE Marker count functions properly only on CW signals or discrete peaks. For a valid
reading, the marker must be ≥26 dB above the noise.
Step Action Notes
1 Move the marker
down the skirt of the
50 MHz peak.
Although the readout in the
active function changes, as long
as the marker is at least 26 dB
above the noise, the counted
value (upper-right corner of
display) does not change.
For an accurate count, the
marker does not have to be
exactly at the displayed peak
2 Enter a new value. • Press BW, Res
BW and enter a
value.
This action makes the
resolution bandwidth (RBW)
the active function and allows
you to experiment with different
resolution bandwidth values.
3 Turn off the marker. • Press Marker,
Off.
