Freq & Span Menu
Figure 14 Freq & Span Menu
In the Freq & Span Menu, the range of frequencies to sweep are specified.
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 the SignalHawk calculate the start and stop fre-
quencies for the sweep. Reducing the span will usually provide more detail and
lower the noise floor. For many measurements, set the center frequency to the
center of the signal being tested.
