Technical Specification R&S CMU-B17
1100.4903.12 TI.8 E-3
R&S CMU200 as RF generator / IQ analyzer
If IQ signals are applied to the receive section of the tester, signal analysis can be performed in the
same manner as when feeding a RF signal. In this connection, modulation analysis, for example, is
useful since it evaluates the quality of an IQ signal. Modulation analysis yields analysis results such as
IQ offset and IQ imbalance, which directly affect IQ signals, or even more complex evaluations such as
error vector magnitude (EVM).

Remarks:
• The listed R&S CMU200 function groups support the option R&S CMU-B17 from SW version V3.10
on:
RF
GSM (GPRS, EGPRS)
IS136
CDMA2000 (IS95)
WCDMA (3GPP FDD)
• Due to used modulation schemes Bluetooth and AMPS standards will not be supported.
• The upgrade of existing units can be performed at R&S Service Center Munich. Installation and
calibration costs must be considered in addition to the price of option R&S CMU-B17. Later on it will
be possible to perform R&S CMU-B17 upgrades at local R&S Service Centers.
• The options R&S CMU-B17 and R&S CMU-B73 use the same mainboard connector of R&S CMU.
Therefore either the R&S CMU-B17 or the R&S CMU-B73 can be ordered for a single instrument.
