The multi evaluation measurement provides additional power control tests and limit
checks, see
chapter 3.2.5.3, "Power Control Limits"
4.2.6.4
Max. Power E-DCH Limits
The conformance test specification 3GPP TS 34.121, section 5.2B "Maximum Output
Power with HS-DPCCH and E-DCH" defines a test for verification of the maximum UE
power with active HS-DPCCH and E-DCH. The test comprises five subtests.
At the end of each subtest procedure, the maximum output power shall be measured
and checked against tolerance values.
You can configure the expected maximum power and a pair of tolerance values in the
configuration dialog. The limit applies to measurements with TPC setup "Max. Power
E-DCH".
Fig. 4-7: Max. Power E-DCH limit settings
3GPP defines the following requirements depending on the subtest and on the power
class of the UE. The default settings correspond to subtest 1 for power class 3.
