MEAS - Analyzer R&S ESCI
1166.6004.12 4.154 E-1
CP/ACP
STANDARD
The CP/ACP STANDARD softkey opens a table for the selection of the settings
according to predefined standards. The test parameters for the channel and
adjacent-channel measurements are set according to the mobile radio standard.
The standards available are listed in the
table on the left.
Note: For the R&S ESCI, the channel spacing is defined as the distance
between the center frequency of the adjacent channel and the center
frequency of the transmission channel. The definition of the adjacent-
channel spacing in standards IS95 B and C, IS97 B and C and IS98 B
and C is different. These standards define the adjacent-channel
spacing from the center of the transmission channel to the closest
border of the adjacent channel. This definition is also used for the
R&S ESCI when the following standard settings are selected:
CDMA IS95 Class 0 FWD
CDMA IS95 Class 0 REV
CDMA IS95 Class 1 FWD
CDMA IS95 Class 1 REV
The selection of the standard influences the following parameters:
• channel spacing and adjacent-channel spacing
• channel bandwidth, adjacent-channel bandwidth, and type of filtering
• resolution bandwidth
• video bandwidth
• detector
• # of adjacent channels
Trace mathematics and trace averaging are switched off.
The reference level is not influenced by the selection of a standard. To achieve
an optimum dynamic range, the reference level has to be set in a way that
places the signal maximum close to the reference level without forcing an
overload message.
The default setting is CP/ACP STANDARD NONE.
IEC/IEEE-bus command: CALC:MARK:FUNC:POW:PRES <standard>
