Narrower RBW allows to distinguish closer signals, but the span is swept considerably slower.
The 10 kHz RBW for Airscout Spectrum 0.3-3 GHz and 30 kHz for Airscout Spectrum 2-8 GHz is most
effectively utilized together with a lower reference level (see
REF
).
The available VBW values are:
• 1 kHz
• 3 kHz
• 10 kHz
• 30 kHz
• 100 kHz*
* Only Airscout Spectrum 2-8 GHz, 24-40 GHz
Narrower VBW stabilizes the displayed trace (i.e. smooths the noise) and allows to see weaker signals
better, but for pulsating signals, a wider VBW should be used.
For most accurate power measurements AVG detector (see
TRACE
) is recommended. If utilizing the
MAX or MIN detector, please note that a narrower VBW must be used. In case the manually selected
VBW is too wide for the current RBW, there is a warning displayed on the screen, VBW indication
under the graph is
red
and the indication “UNCAL” is put under the battery symbol.
