RBS3202 Test with CMU300 and RNC/Iub SIM

1CM56_E 12 Rohde & Schwarz

• Set the starting output level to –70 dBm (Generator Level / Total

Transmit Power: -70 dBm)

• Set the UL frequency or channel number to be used on the RNC

simulator (Generator Settings / Channel or Frequency). Note: In

normal conditions the UMTS UL frequency is 190 MHz below the

DL frequency.

• Set the UL scrambling code to be used by the RNC simulator

(Channel Settings / Dedicated Channel / Scrambling Code).

Default value for the RNC simulator: 100 hex

• Set the required offset of 1024 chips between DL and UL (Channel

Settings / Dedicated Channel / CPICH – UL DPCH Offset: 1024

Chips).

• Check whether the 3GPP reference measurement channel is set at

12.2 kbps incl. PN9.

• Set the TFCI Bits to 1100000000. (Channel Settings / 3GPP

Reference Channel / TFCI Bits: 1100000000)

• Close the Generator Configuration menu and start the generator (press

the Generator softkey on the right of the screen and the ON / OFF

hardkey). The message "Waiting for Synchronisation" should appear

and then disappear when the TTI trigger occurs. The TTI trigger is

made available on the BTS relatively infrequently (approx. 1 to 2 times

per minute).

• Check whether the BER test is currently operating correctly. For this to

be the case, all error rates on the BER analyzer must be 0% and

incoming bits must be present.

• Carry out receiver measurements by reducing the output level in

accordance with the values mentioned in [1] (softkey Total TX Power).
