Reference Measurement Channels (RMC)
3GPP W-CDMA real-time signal generation personality provides reference measurement
channels at 12.2, 64, 144, and 384 kbps. This option also provides transport layer coding for
AMR 12.2 (adaptive multi-rate) and UDI 64 (unrestricted digital information) protocols.
The signal generator provides one-button setup capabilities for transport channel
configuration. The dedicated physical channel DPDCH is predefined by pressing the
Ref
Measure Setup
softkey (or sending the appropriate SCPI commands) and selecting the desired
RMC. RMC 12.2 kbps is the factory default selection.
Table 15-4 describes the uplink reference measurement channel (RMC) configurations.
