Reference Measurement Channels (RMC)
The W-CDMA real-time signal generation modulation format provides reference measurement channels
(RMC) 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. Along with user defined
parameters for the DPCH, the ESG also supports the predefined 12.2 kbps RMC, 64 kbps RMC, 144 kbps
RMC, AMR 12.2 kbps, and UDI 64 kbps with compressed mode.
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.
