RBW
Defines the resolution bandwidth. The available resolution bandwidths are specified in
the data sheet. Numeric input is always rounded to the nearest possible bandwidth.
If "AUTO" is selected, the resolution bandwidth is coupled to the selected span (for
span > 0). If the span is changed, the resolution bandwidth is automatically adjusted.
If the resolution bandwidth is defined manually, a green bullet is displayed next to the
"RBW" display in the channel bar.
For more information see chapter 6.5.1.1, "Separating Signals by Selecting an Appro-
priate Resolution Bandwidth" , on page 403.
For measurements on I/Q data in the frequency domain, the maximum RBW is 1 MHz.
For EMI measurements using the quasipeak detector, the 1 MHz RBW filter is not
available (see chapter 5.13.3.1, "Resolution Bandwidth and Filter Types" ,
on page 290).

VBW
Defines the video bandwidth automatically or manually.
For more information see chapter 6.5.1.2, "Smoothing the Trace Using the Video
Bandwidth" , on page 404.
"Auto" The video bandwidth is coupled to the resolution bandwidth. If the
resolution bandwidth is changed, the video bandwidth is automatically
adjusted.
"Manual" For manual mode, define the bandwidth value. The available video
bandwidths are specified in the data sheet. Numeric input is always
rounded to the nearest possible bandwidth.
If the video bandwidth is defined manually, a green bullet is displayed
next to the "VBW" display in the channel bar.
