Generating a DPCCH/DPDCH with a Reference Measurement Channel
The tasks in this procedure teach you how to set up a pre-defined DPDCH reference measurement channel.
Configuring the RF Output
1. Preset the ESG.
2. Set the carrier frequency to 1.95 GHz.
3. Set the carrier power to −10 dBm.
4. Turn on the RF output.
Selecting a Reference Measurement Channel
The ESG provides a single-softkey solution for configuring the transport layer coding according to the
reference measurement channel’s (RMC) 3GPP specifications.
1. Press
Mode > W-CDMA > Real Time W-CDMA > Link Down Up to Up.
2. Press
Link Control > Ref Measure Setup > RMC 384 kbps (25.141).
3. Press
PhyCH Setup > DPCH Power Setup.
4. Press
Adjust Code Domain Power > Scale to 0dB.
This adjustment changes only the displayed power values, the I/Q channels are automatically adjusted to
achieve zero dB power. For more information on channel power, see “Adjusting Code Domain Power”
on page 548.
5. Press
Mode Setup to return to the top level W-CDMA menu.
In this task you have selected a predefined 384 kbps reference measurement channel setup that conforms to
the 3GPP standards. For more information on reference measurement channels, see “Reference
Measurement Channels (RMC)” on page 550.
