R&S ESU Instrument Functions
Analyzer Mode
As of firmware version 4.4x, the weigthing filter parameters can be manually con-
trolled for USER ACP measurements. To change the weighting filter settings when
using predefined standards, proceeed as follows:
Select the predefined standard with the CP/ACP STANDARD softkey.
Save the settings as a user defined standard with the SAVE AS USER STD
softkey.
Select the user defined standard you just saved with the SELECT USER STD
softkey.
Since the standard in use is now a user defined standard, you can change the
weighting filter settings as required.
Save the user standard again to keep the current settings.
Weighting filters are not available for FAST ACP measurements and for Multi Carrier
ACP measurements.

OFFSET
Defines an additional level offset to the measured mean power to be taken into
account for the analyzer's reference level setting.
It is a modification to the ADJUST REF LEVEL function specific to user standards.
Proceed as follows to adjust the offset value for a predefined standard:
Select a predefine standard with the CP/ACP STANDARD
Changing the TX channel filter parameter will additionally adjust the ADJ channel
settings as long as the current settings for TX and ADJ channels are identical. As
most of the digital standards require identical settings for all channels it is there-
fore required to configure the TX channel weigthing filter parameter only.
Change the ADJ weigthing filter settings first, if different settings are required for
TX and ADJ channels.
