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 RBW Auto for automatic resolution bandwidth selection, or press RBW
Manual
and use the Up/Down arrow key to select the resolution bandwidth.
Press ENTER to set the resolution bandwidth.
Step 3. Press
VBW Auto for automatic video bandwidth selection, or press VBW Manual
and use the Up/Down arrow key to select the video bandwidth. Press ENTER to
set the video bandwidth. Press the
Back soft key to return to the bandwidth
menu.
