Note: *0 Hz is available only in zero span.
Full Span
Set the span of the analyzer to the maximum.
Zero Span
Set the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal
the center frequency and the horizontal axis will denote time. The analyzer
measures the time domain characteristics of the amplitude of the corresponding
frequency point on the input signal.
Key Points:
As opposed to Non-zero span, the screen shows the time domain characteristics of
the fixed frequency component of the signal in zero span mode.
The following functions are invalid in Zero span mode:
FREQ
: Peak->CF and Signal Track;
SPAN
: Zoom In and Zoom Out;
Marker->
: Mkr->CF, Mkr->Step, Mkr->Start, Mkr->Stop, MkrΔ->CF and
MkrΔ->Span;
