Selecting Bandwidth Parameters
Both resolution bandwidth (RBW) and video bandwidth (VBW) can be automatically or
manually coupled. Auto coupling of the RBW links the RBW to the span. That is, the wider
the span, the wider the RBW. Auto coupling is indicated on the display as
RBW XXX
. When
the RBW is manually coupled, it can be adjusted independently of the span. Manual RBW
coupling is indicated on the status window as
RBW* XXX
.
Auto coupling of the VBW links the VBW to the RBW. That is, the wider the RBW, the
wider the VBW. Auto coupling is indicated on the display as
VBW=Auto
. When the VBW
is manually coupled, it can be adjusted independently of the RBW. Manual VBW coupling
is indicated on the display as
VBW* XXX
.
Step 1.
Press the
MEAS/DISP
key and the
Bandwidth
soft key to display the bandwidth
menu.
Step 2.
Press
