ESIB
RBW / VBW
PULSE [.1]
The RBW / VBW PULSE softkey sets the following coupling ratio:
video bandwidth = 10 x resolution bandwidth
or
video bandwidth = 10 MHz (= maximum video bandwidth).
This coupling ratio is recommended when the amplitude of pulsed signals is
to be measured. The IF filter characteristics alone determine the pulse shape.
No additional weighting is provided by the video filter.
This setting is only effective for the VBW AUTO selection in the main menu.
IEC/IEEE-bus command :[SENSe:]BWIDth:VIDeo:RATio PULSe
RBW / VBW
NOISE [10]
The RBW / VBW NOISE softkey sets the following coupling ratio:
video bandwidth = resolution bandwidth/10
At this coupling ratio, noise and pulsed signals are suppressed in the video
section. For noise signals, the ESIB displays the average value.
This softkey is disabled unless VBW AUTO is selected in the main menu.
IEC/IEEE-bus command
:[SENSe:]BWIDth:VIDeo:RATio NOISe
RBW / VBW
MANUAL
The RBW / VBW MANUAL softkey activates the entry of the coupling ratio for
resolution bandwidth to video bandwidth.
The range for the RBW/VBW ratio is 0,001 to 1000.
This softkey is disabled unless VBW AUTO is selected in the main menu.
IEC/IEEE-bus command :[SENSe:]BWIDth:VIDeo:RATio 10
SPAN / RBW
AUTO [50]
The SPAN / RBW AUTO [50] softkey sets the following coupling (rounding is
made to the next higher value):
resolution bandwidth = span/50
This coupling corresponds to the default state.
This softkey is disabled unless RBW AUTO is selected in the main menu.
IEC/IEEE-bus command
:[SENSe:]BWIDth[:RESolution]:RATio 0.02
SPAN / RBW
MANUAL
The SPAN / RBW MANUAL softkey activates the entry for the coupling of
resolution bandwidth and span.
The range for the SPAN/RBW ratio is 1 to 10000.
This softkey is disabled unless RBW AUTO is selected in the main menu.
