Trigger, Capture, Analyze Your RF Signal

Quickly Solve Design,
Production or
Operational Problems
With Comprehensive
Characterization of
Time-varying and
Transient RF Signals

Define issues and solve problems faster by

characterizing your device, system or signal

more completely and rapidly than previously

possible with swept spectrum analyzers.

Tektronix RSA2200A and RSA3300A Series

Real-time Spectrum Analyzers capture

many signals not viewable on swept

spectrum analyzers by seamlessly capturing

and storing a span of RF frequencies all at

*1

one time.

Once a signal is captured, it

can be viewed simultaneously and ana-

lyzed in time-correlated frequency, time

and modulation domains. RSA Series instru-

ments include not only Real-time Spectrum

Analyzer fast-signal capture, internal memory

and modulation analysis but also functionality

and operation of a swept spectrum analyzer

for looking at very wide spans, all in an

integrated, transportable package.

See Tektronix Real-time Spectrum Analysis Technical Brief
(lit # 37W-17252-0) for an explanation of how RTSA works
and its unique capabilities.

RSA Series Spectrogram uniquely shows
time-varying signal behavior in frequency
change/stability, spectrum occupancy,
pulsed signal timing, power change and
more! The sample above shows the fre­quency settling characteristic of a
transmitting device.

Time-correlated multi-domain view provides
a new level of insight about design or
operational problems and possible
solutions. This example includes frequency,
time, and modulation domain views of an
AM-modulated pulsed signal with pulse­to-pulse phase variation measured in the
modulation domain.

RSA2200A Series •RSA3300A Series

Trigger, Capture,
Analyze

You can easily catch
an elusive RF signal
and analyze it at your
convenience

Sensitive and fast, RSA Series Real-time

Spectrum Analyzer triggering easily

captures unknown, periodic or intermittent

signals. Using the Tektronix exclusive

Frequency Mask Trigger, you can configure

a custom frequency domain mask including

signal guard bands and levels then trigger

on events isolated to a specific frequency or

frequency range. As signals are captured,

they are automatically saved to RSA internal

memory, making it easy to perform in-depth,

time-correlated analysis across the frequency,

time and modulation domains with no exter-

nal computer required! Quick-to-set-up

IF Level and Power (Span Bandwidth) triggers

provide very convenient capture of signals

in applications such as incident carrier-and-

response interaction between two devices

or burst signal carrier ramp up. Continuous

Trigger Mode ensures a sequence of events

are automatically captured into memory;

you capture only the events and not time in

between, maximizing memory efficiency and

minimizing analysis time.
