Freq & RBW Tab for ACPR and MCPR Displays
The Freq & RBW tab specifies frequency parameters for the Channel Power & ACPR measurements and
MCPR measurement.
Setting
Description
Meas Freq
Specifies the center/measurement frequency.
Step
The Step control sets the increment/decrement size for the adjustment of the center
frequency. If Auto is enabled, the analyzer will adjust the Step size as required.
RBW
Select Auto or Manual. Adjusts the RBW for the entire measurement. This setting is
Independent of the Spectrum view's RBW setting.
VBW
Adjusts the VBW (Video Bandwidth) value. VBW Maximum = current RBW value. VBW
Minimum = 1/10,000 RBW setting.
xxx
NOTE. While the center frequency and step settings on this control tab are shared between ACPR, MCPR
and Occupied Bandwidth, the RBW setting is not shared. The RBW setting is unique for each measurement.
VBW
The VBW setting enables/disables the Video Bandwidth filter. VBW is used in traditional swept analyzers
to reduce the effect of noise on the displayed signal. The VBW algorithm in the analyzer emulates the
VBW filters of traditional swept analyzers.
The maximum VBW value is the current RBW setting. The minimum VBW value is 1/10,000 of the
RBW setting.
Measurement Params for ACPR and MCPR Displays
The Measurement Params tab is where you set parameters that control the ACPR and MCPR measurements.
