Channel Power 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 and set the filter bandwidth.

Res BW

Sets the value of the resolution bandwidth (RBW). 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, 1xEVDO, LTE, LTETDD, WLAN

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

[:SENSe]:CHPower:BANDwidth[:RESolution]?

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

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

Example: CHP:BAND 5 MHz

CHP:BAND?

CHP:BAND:AUTO ON

CHP:BAND:AUTO?

Notes: You must be in the W-CDMA mode, cdma2000 mode, LTD 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 the RBW. As the RBW changes, the sweep time (if

set to Auto) is changed to maintain amplitude calibration.

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

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

VBW/RBW (10:1).

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

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

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

bandwidths are used regardless of other analyzer settings.
