Chapter 2 WCDMA Call Mode
Testing User Equipment on WCDMA channels
60 WCDMA Options Version 6.20
The first screen area shows the results of the UE measurements. You can activate
and deactivate the UE measurement by selecting or deselecting the UE Meas
[ON/OFF] control box.
The second part of the measurement results display shows the BER and BLER
measurement results.
The statistical evaluation of the measurement results is displayed as current,
minimum, average and maximum values. The bar displays give a graphical repre-
sentation of the test results relative to the measurement limits. The Count field
shows the total number of measurements used to calculate the statistical results.
The limit values for the BER/BLER measurements are set in the Measurement
Limits Parameter menu. For details on setting or modifying systems parameters
please refer to “Measurement Limits” on page 71. For descriptions of the basic
test parameters that can be set in the lower half of the measurement screen refer
to “Test parameters” on page 39.
CPICH RSCP
[dBm]
This field indicates the Common Pilot Channel Received
Signal Code Power, which is the average power of the
received signal after despreading and combining the
signal. It is important how the UE received the CPICH
transmitted by Node B. Based on this value the Preamble
Initial Power is calculated. This value indicates the
accuracy of the UE’s CPICH RSCP measurement.
UE Power
[dBM]
This field indicates the UE’s power class and the maxi-
mum power which can be transmitted in dBm. When
WCDMA bands II or III are selected, power classes 1 and
2 are omitted.
BER [%]
The Bit Error Rate indicates the number of erroneous bits
in relation to the total number of bits in a transmission.
It is expressed as a percentage. A BER of 0 would be
ideal.
According to WCDMA specifications the BER value shall
not exceed 0.001 at the conditions specified in Table 2
on page 59.
BLER [%]
The Block Error Rate indicates the number of erroneous
data blocks in relation to the total number of data blocks
in a transmission. It is expressed as a percentage. A BLER
of 0 would be ideal.
