Bandwidth 

BW key sets the resolution bandwidth (RBW). The resolution bandwidth and the 

sweep time are related. Please take into account how the sweep time is effected by 

the resolution bandwidth.  

Resolution Bandwidth Setting (RBW) 

 

Description 

The RBW (Resolution Bandwidth) defines the width of the IF 

(intermediate frequency) filter that is used to separate signal 

peaks from one another. The narrower the RBW, the greater 

the capability to separate signals at close frequencies. But it 

also makes the sweep time longer under specific frequency 

spans (the display is updated less frequently).  

Operation 

1.  Press 

BW

> 

RBW[F1]

 and set the RBW to Auto or Man. 

2.  Set the resolution bandwidth and unit for Man mode. 

 

Mode: 

Frequency Range: 

Auto, Man 

1MHz, 300kHz, 100kHz 

 Note 

The manual RBW is only available when the 

span

≤

10MHz. If the span is greater than 10MHz then the 

RBW is automatically set to Auto.
