R&S ESU
For some standards, the channel power and the adjacent-channel power are to be
weighted by means of a root-raised cosine filter corresponding to a receive filter.
This type of filtering is switched on automatically for both methods on selecting the
standard (e.g. NADC, TETRA or 3GPP W-CDMA).
Addition of firmware starting from version 4.3x:
As of firmware version 4.3x it is possible to configure overlapping adjacent chan-
nels. Based on a common carrier channel setting, it is now possible to measure with
two slightly different ADJ channel settings with one single measurement at the same
time.
Example:
ACP Measurement A and Measurement B are using identical TX channel settings
(Channel Bandwidth).
The ADJ settings for Measurement A and measurement B are different.
It is now possible to do both measurements at the same time.
• Configure the ACP measurement with number of ADJ channels = 2.
• Define ADJ settings (bandwidth, spacing) as required for measurement A.
• Define ALT1 settings (bandwidth, spacing) as required for ADJ channel of
measurement B
• Perform the ACP measurement
• Read the ACP measurement result
The Carrier Power belongs to measurement A and B
The ADJ result is the ADJ result of measurement A
The ALT1 result is the ADJ result of measurement B.
This feature is only supported for ACP but not for Multi Carrier ACP measurement.
