Functions and Measurements
Improving Frequency Resolution and Accuracy
50
The marker readout in the active frequency function changes
while the counted frequency result (upper- right corner of
display) does not. For an accurate count, the marker need
not be placed at the exact peak of the signal response.
6
To turn off the marker counter:
Press
Marker > Function > Off
.
NOTE
The Frequency counter properly functions only on stable, CW signals
or discrete spectral components. The marker power level must be
greater than 40 dB above the displayed noise level.
NOTE
When using the frequency counter function, the ratio of the resolution
bandwidth to the span must be greater than 0.02.
