The "Max. Power E-DCH" TPC setup sends a TPC pattern suitable for subtest 1 to 4, if
an "RMC+HSPA" test mode connection is configured. If an "HSPA" test mode connec-
tion is configured, it sends a TPC pattern suitable for subtest 5.
The signaling application provides a wizard for comfortable configuration of the signals
required for the individual subtests, see
chapter 2.2.17, "WCDMA Wizards"
Please note that measurement resources are required by the "Max. Power E-DCH"
setup for monitoring of the E-TFCI. Do not execute an HSUPA measurement in parallel
(for example the E-HICH measurement), as this may cause a resource conflict. In that
case, execution of the "Max. Power E-DCH" setup will either be slowed down, or fail
(TPC state "Missing Resource").
For a detailed description of a combined signal path measurement including subtest 1
to 5, see
chapter 2.3.4, "Maximum Power Measurements with E-DCH"

TPC Test Steps for Inner Loop Power Control
The conformance test specification 3GPP TS 34.121, section 5.4.2 "Inner Loop Power
Control" defines the TPC test steps A to H inducing a power ramp of the following
shape:

The R&S
CMW offers most of these steps as fixed TPC pattern setups, see table
below.
