Interface Problems

The 3066 and 3086 are DC to 3 GHz real-time spec­trum analyzers that allow the seamless capture of
frequency spectra with spans up to 30 MHz
(5 MHz – 3066). This allows the spectrum of burst
signals, such as those from GSM, IS-136, PDC or par­tial rate CDMA mobile stations, to be easily captured
and examined. Real-time spectrum analyzers take a
very different approach compared to traditional
sweeping spectrum analyzers. Rather than acquiring
one frequency step at a time, the real-time instrument
captures a block of frequencies all at once. Because
the instrument samples these full frames constantly
(rather than waiting for each discrete frequency step
to be measured), the signal can come or go as it
pleases and the real-time spectrum analyzer will
detect the change instantly.

The 12.1 in. color TFT display allows easy viewing
of spectrum, waterfall displays, spectrograms and
digital modulation analysis screens. Constellation
and vector diagrams can be displayed, as well as
frequency, phase, magnitude, I and Q versus time,
for in-depth analysis of digitally modulated signals.
Users can move a marker through the time record
and analyze the modulation at any point. In
particular, signals with symbol rates up to

20.48 Msymbols/sec (3066 – 5.3 Msymbols/sec) may
be analyzed during and after capture. This facilitates
analysis of W-CDMA signals with chip rates up to

16.384 Mcps.

In addition, a frequency mask trigger
allows capture of randomly occurring or
infrequent signals such as intermittent
spurious emissions. If the user is not
interested in the period between trans­mission bursts, the frequency mask trigger
allows capture of the “burst-on” periods,
thus maximizing the number of bursts
that can be captured in memory for subse­quent spectral, time or modulation
analysis. The user can graphically define
the frequency trigger mask; this allows
the trigger condition to be generated by a
particular event in the frequency domain
irrespective of other activity within the
displayed span. This is a major benefit
when the trigger condition is used to cap­ture signals arising from intermittent
spurious or spectral re-growth events.

Option 1S, automatic waveform record­ing, can be used to store multiple memory
blocks to the internal hard drive without
operator intervention. This enables unat­tended monitoring and recording of
transient events for later review.

A 1000:1 zoom capability permits analy­sis to be performed on an individual
signal in a multi-signal environment.

Option 16: IS-95 and W-CDMA
Code Domain Power for
the 3086

CDMA and W-CDMA Base Station devel­opers use code domain power
measurements to verify correct operation
of their designs. BTS amplifier designers
rely upon Complementary Cumulative
Distribution Functions (CCDF) to verify
the input and output amplitude distribu­tions of their test waveforms. When
equipped with options 16 and 20, the
3086 now meets these needs for IS-95 and
W-CDMA designs. The real-time nature of
the 3086 spectrum analyzer brings unique
advantages to this application.

The 3086 with option 16 processes the W­CDMA down-link signals as defined in
“Specifications for W-CDMA Mobile
Communication System Experiment
Version 1.1” and offers extensive analysis
capability including:

Code-domain power

The analyzer measures the relative
power to total power for each channel
with 1024 channels maximum

Time vs. code-domain power

The analyzer measures the relative
power at symbol points for each
channel as a time series

Code-domain power spectrogram

The analyzer measures the code­domain power continuously for
maximum 160 slots (0.1 s) and
displays spectrogram for each slot

Modulation accuracy

The analyzer measures EVM (error
vector magnitude), amplitude error,
phase error, waveform quality, and
origin offset for each channel

For customers who need code domain
analysis of IS-95 base station signals,
option 16 also provides code power mea­surements for IS-95 signals over a 6144
symbol period.

Option 20 CCDF (3066 and

3086) Feature Summary

Option 20 records the statistical nature of
a signal, and plots the probability of
exceeding a measured average value for
the waveform. A large amount of data is
collected in the memory of the 3086, and
Complementary Cumulative Distribution
Function (CCDF) can be shown over
selected periods of time to determine the
effect of code selection or multi-carrier
additions on the peak-to-average ratio of
the waveform. Base station amplifier
designers use this information to judge
the distortion performance of their prod­ucts. The rapid changes that occur in base
station power outputs require a real-time
bandwidth higher than the occupied
bandwidth of the signals measured. The
3086 provides unique capability due to
its 30 MHz real-time bandwidth, allowing
CCDF measurements on up to 6 W-CDMA
carriers simultaneously. In the 3066,
CCDF measurements over a 5 MHz real­time bandwidth is possible.

Option 15: IS-95 Code Domain
Power for the 3066 Spectrum
Analyzer

OPTION 15 (3066) FEATURE SUMMARY:

Option 15 offers the measurement func­tions listed below:

Code-domain power

Measures the relative code power to
total power for each channel

Code-domain power vs. Time

The analyzer measures the code­domain power continuously for 6144
symbols (0.32 s) maximum and dis­plays spectrogram for each symbol

Modulation accuracy and vector
display

Measures EVM (error vector magni­tude), amplitude error, phase error,
waveform quality, and origin offset for
