3-2 W-CDMA/HSPA+ Measurements
W-CDMA/HSPA+ Signal Analyzer
3-4
PN: 10580-00234 Rev. V
3GPP MG
Peak to Average Power
Peak to Average power is the ratio of the peak power and the RMS power of the signal
calculated over one frame interval and is displayed in dB.
Peak CD Error (Peak Code Domain Error)
PCDE takes the noise and projects the maximum impact it will have on all OVSF codes.
PCDE is the maximum value for the code domain error for all codes (both active and inactive).
In the 3GPP standard, in order to address the possibility of uneven error power distribution
in W-CDMA, the EVM measurement has been supplemented with PCDE. The 3GPP standard
requires that the PCDE not exceed –33 dB at a spreading factor of 256.
Ec
Ec is a measurement of energy. Ec is determined by multiplying CPICH by the chip time.
Ec/Io
The pilot power compared to the total channel power. Ec/Io is displayed in text-only displays
and in OTA measurement displays.
Pilot Dominance
The strength of the strongest pilot compared to the next strongest pilot in the same channel.
This should be >10 dB in order to make good measurements.
OTA Total Power
The total channel power is also called (Io) and displayed in dBm.
CPICH Power
CPICH power is the power of the Common Pilot Channel power displayed in dBm.
P-CCPCH Power
P-CCPCH power is the Primary Common Control Physical Channel power displayed in dBm.
S-CCPCH Power
S-CCPCH power is the Secondary Common Control Physical Channel power displayed in
dBm.
P-SCH Power
P-SCH power is the Primary Sync Channel power displayed in dBm.
S-SCH Power
S-SCH power is the Secondary Sync Channel Power displayed in dBm.
PICH
PICH is the Paging Indicator Channel Power.
HSPA+ Power versus Time Display
Select the code and set the time to display how the code is varying over time. In CDP view,
HSPA+ signals are displayed in orange.
Constellation
In the HSPA+ view, the symbol constellation for the selected code is displayed (16QAM or
QPSK).
