Conventions
This manual uses the following conventions:
H Front-panel button and control labels are printed in the manual in upper case
text. For example, SPAN, PEAK, PRINT. If it is part of a procedure, the
button or control label is printed in boldface. For example:
Press SPAN.
H To easily find buttons on the front panel, the area name label is printed together
with the button by concatenating with a colon (:), as in MODE: DEMOD,
VIEW: SCALE, MARKERS: SELECT, etc. For example:
Press the MODE: DEMOD key.
H Menu and on-screen form titles are printed in the manual in the same case
(initial capitals) as they appear on the analyzer screen, such as Span, Source,
and Channel Power. If it is part of a procedure, the menu title is shown in
boldface. For example:
Press the Source side key.
H A list of keys, controls, and/or menu items separated by an arrow symbol
(Õ) indicates the order in which to perform the listed tasks. For example:
Select RBW/FFT Õ Filter Shape...Õ Gaussian.

Signal Type
Definition of Analysis
The analyzer supports three types of W-CDMA uplink signals:
H DPDCH (Dedicated Physical Data Channel) /
DPCCH (Dedicated Physical Control Channel)
H PRACH (Physical Random Access Data Channel)
H PCPCH (Physical Common Packet Channel)
The analyzer covers the W-CDMA uplink parameters listed in Table 1–2.
NOTE. The analyzer de-spreads DPCCH and the control part of the incoming
signal, using the frequency and phase to establish synchronization. If the level of
DPCCH or the control part is much lower than the level of the other channels,
accurate analysis may not be performed.

Measurement Functions
Getting Started
The analyzer has the following measurement functions:
H Code domain power
Measures power relative to the total power for each channel.
H Time vs. Code domain power
Measures the relative power at symbol points for each channel in time series.
H Code domain power spectrogram
Measures the code domain power continuously for up to 150 slots
(0.1 sec) and displays spectrogram for each slot.
H Vector/Constellation
Measures the vector loci and chip points for entire signals, as well as
constellation at symbol points for each channel.
H Modulation accuracy
Measures EVM (Error Vector Magnitude), amplitude and phase errors,
waveform quality, and origin offset for each channel.
Measures PCDE (Peak Code Domain Error), amplitude, Frequency, and
phase errors, waveform quality, and origin offset for a time slot.
Measurement Process
The analyzer processes the input signals internally as shown in Figure 1–2.
1
Perform flatness correction and filtering.
DPDCH/DPCCH PRACH, PCPCH
