CDMA2000
The following tests can be carried out only if the CDMA2000 (R&S CMU-K8x) software options are
installed and enabled by entering a key code.
TX CDMA2000 Modulation
Only with options R&S CMU-K83, R&S CMU-K84, R&S CMU-K85 or R&S CMU-K86:
The CDMA2000 modulation parameter of a TX path is measured.
Preparation: Test setup TX5:
 Connect spectrum analyzer FSIQ to RF3 OUT.
Control:  Set R&S CMU generator to specified RF frequency.
Settings at R&S CMU:
CDMA2000 450 MHz (CDMA2000 Cellular, CDMA2000 PCS, CDMA2000 IMT-
2000) Signaling Connection Control
CDMA Power = -7 dBm
Traffic level = OFF, Paging level = OFF, Sync. level = OFF, Pilot level = - 7 dB,
OCNS level = OFF

Set Reference Level
Rho Factor Measurement , Carrier Suppression
Annotation:
FSIQ can perform this measurement only on one active channel
The R&S CMU CDMA2000 Output level will only be equal to displayed CDMA
power with OCNS=AUTO.
Test: Rho factor and carrier suppression are measured according to CDMA2000
recommendation.
