Notes
You must be in the Spectrum Analysis mode, W-CDMA mode, cdma2000 mode, TD-SCDMA
mode,ISDB-T mode, CMMB mode, LTE mode, LTE TDD mode,BLUETOOTH mode, WLAN mode,
1xEVDO mode, MSR or WIMAX OFDMA mode to use this command. Use:INSTrument:SELect to set
the mode.
Dependencies
When using the average detector with either Sweep Time set to Man, or in zero span, the VBW
setting has no effect and is disabled (grayed out).
Couplings
Video bandwidth (VBW) is coupled to RBW. As the resolution bandwidth changes, the video
bandwidth (if set to Auto) changes to maintain the ratio set by VBW/RBW.
Sweep Time is coupled to Video Bandwidth (VBW). As the VBW is changed, the sweep time (when
