3 Spectrum Analyzer Mode

3.5 ACP Measurement

3.5.9 BW

Opens the BW menu, which contains controls for the Resolution Bandwidth and

Video Bandwidth functions of the instrument.

The Resolution BW functions control filter bandwidth and filter type. There are two

filter types, Gaussian and Flattop. The Gaussian filters have a response curve that is

parabolic on a log scale. The Flattop filter shape is a close approximation of a

rectangular filter.

3.5.9.1 Settings

Contains the basic Bandwidth functions. In most measurements it is the only tab

under Bandwidth.

Res BW

Activates the resolution bandwidth active function, which allows you to manually set

the resolution bandwidth (RBW) of the instrument.

Normally, Res BW (Auto) selects automatic coupling of Res BW to "Span" on page

955. To decouple the resolution bandwidth, press the Auto/Man toggle on the Res

BW control, or simply enter a different value for Res BW.

When Res BW is manually selected, it may be returned to the coupled state by

pressing the Auto/Man toggle on the ResBW control. This may also be done by

pressing "Auto Couple" on page 2017 or by performing a Preset.

Remote Command

[:SENSe]:ACPower:BANDwidth[:RESolution] <bandwidth>

[:SENSe]:ACPower:BANDwidth[:RESolution]?

Example

:ACP:BAND 5 MHz

:ACP:BAND?

Notes For numeric entries, all Res BW Types choose the nearest (arithmetically, on a linear scale, rounding

up) available Res BW to the value entered

The setting and querying of values depend on the current bandwidth type

This parameter is preset by "Meas Method" on page 970. Preset values are:

Modes Values
