Freq & Span Menu
Figure 45 Freq & Span Menu
In the Freq & Span Menu, the range of frequencies to be tested is specified. The
Spectrum Analyzer can sweep frequencies between 100 kHz and 3.6 GHz.
Frequencies can be selected at spans from 1 kHz up to the entire range of the
instrument.
Note: Information obtained from readings set below the minimum
rating may not be accurate.
These frequencies can be set to sweep by one of the following methods:
 Set the Center Freq and Freq Span.
 Set the Start Freq and Stop Freq.
 Select the Full Span of the instrument.
 Select a band from the Freq List.
The most common of these methods is to set the center frequency and a fre-
quency span (a range) and let SignalHawk calculate the start and stop fre-
quencies. Reducing the span (with RBW and VBW both on auto modes) will
usually speed up the sweep, provide more detail, and lower the noise floor.
Unless specified otherwise, set the center frequency to the center of the sig-
nal being measured.
