Occupied Bandwidth Measurement

Accesses a menu of functions that enable you to specify and control the video and resolution bandwidths. You can also select the type of filter for the measurement.

Res BW

Sets the resolution bandwidth for the current measurement. If an unavailable bandwidth is entered with the numeric keypad, the closest available bandwidth is selected.

Key Path: Front-panel key

Initial S/W Revision: Prior to A.02.00

Key Path: BW

Mode: WCDMA, C2K, WIMAX OFDMA, TD-SCDMA, 1xEVDO, LTE, LTETDD,

BLUETOOTH, WLAN

Remote Command: [:SENSe]:OBWidth:BANDwidth[:RESolution] <bandwidth>

[:SENSe]:OBWidth:BANDwidth[:RESolution]?

[:SENSe]:OBWidth:BANDwidth[:RESolution]:AUTO ON|OFF|1|0

[:SENSe]:OBWidth:BANDwidth[:RESolution]:AUTO?

Example: OBW:BAND 250000

OBW:BAND?

OBW:BAND:AUTO OFF

OBW:BAND:AUTO?

Notes: You must be in the W-CDMA mode, cdma2000 mode, TD-SCDMA mode,

BLUETOOTH mode, LTE mode, LTE TDD mode, WLAN mode, 1xEVDO

mode, or WIMAX OFDMA mode to use this command.

Use:INSTrument:SELect to set the mode.

Couplings: Sweep time is coupled to RBW. As the RBW changes, the sweep time (if set

to Auto) is changed to maintain amplitude calibration.

Video bandwidth (VBW) is coupled to RBW. As the resolution bandwidth

changes, the video bandwidth (if set to Auto) changes to maintain the ratio of

VBW/RBW (10:1).

When Res BW is set to Auto, the resolution bandwidth is auto-coupled to

span. The ratio of Span/RBW is approximately 106:1 when auto coupled.

When Res BW is set to Man, bandwidths are entered manually, and these

bandwidths are used regardless of other analyzer settings.
