The following display selections are available through the
MEAS/DISP
key:
CDP
— When CDP is selected, the display shows Code Domain Power as 64 or 128 bit re-
versed Walsh codes in graphical format. Pilot power, Channel Power, Frequency Error,
Rho, and Noise Floor will be displayed and three strong pilots will be displayed in OTA
measurement.
Text Only
— Displays Pilot Power, Channel Power, Ec/Io, Rho, Tau, Frequency Error and
Carrier Feed Through in a text format.
Over The Air Meas
— Available only with Option 33, OTA can display the six strongest pi-
lots with Tau and Ec/Io or the two strongest multipaths with Ec/Io related to the strongest
pilot. Pilot power, Noise floor, Channel Power, Pilot Dominance, delta Sync, delta Page,
delta Quick Page and Multipath Power will be displayed as a numerical format.
RF Meas
— Available only with Option 42, RF measurements displays the selected channel
spectrum and Channel Power, Freq Error, Measured Occupied Bandwidth and Noise Floor
in a numerical format.
Measurements
Code Domain Power
Code Domain Power displays how much of the channel power is in each Walsh code.
Power is normalized to the channel power, so if a code reads –10dB, it means that the
power in that code is 1/10th of the channel power. Colors are applied according to the fol-
lowing table:
Pilot

Sync

Pilot Power
Pilot power is the total power in the pilot channel. This is normally a constant for a base
station. When the Cell Master is connected to the base station, if the measured power is un-
expected, check that the entered power offset is correct and that the connections are tight.
Unexpected readings may indicate an incorrect power setting at the base station.
For Over The Air (OTA) measurements, the pilot power will vary as the signal path from
the transmitter to receiver varies.
Ch Power RMS
Channel power is the total power broadcast in the 1.25 MHz wide CDMA channel speci-
fied.
