Data Sheet
Revolutionary DPX™ spectrum display discovers events that other analyzers miss. This is
an off-the-air capture of a frequency-hopping signal jammed by large interference.
Discover and interpret complex behaviors of
your time-variant signals
The RSA3000B Series makes it easy for you to discover design issues that
other signal analyzers miss. The revolutionary DPX Live RF spectrum
display offers an intuitive live color view of signal transients changing over
time in the frequency domain, giving you immediate confidence in the
stability of your design or instantly displaying a fault when it occurs. This
live display of transients is impossible with other signal analyzers. Once
a problem is discovered with DPX, the Real Time Spectrum Analyzer
(RTSA) can be set to trigger on the event in the frequency domain,
capture a continuous time record of changing RF events and perform
time-correlated analysis in all domains. You get the functionality of a
high-performance vector signal analyzer, a spectrum analyzer, and the
unique discover-trigger-capture-analyze capability of a Real Time Spectrum
Analyzer – all in a single package.
Performance You Can Count On
Depend on Tektronix to provide you with performance you can count on. In
addition to industry-leading service and support, this product comes backed
by a one-year warranty as standard.

Characteristics
Discover
The DPX™ spectrum processing engine brings live analysis of transient events to
spectrum analyzers. Performing more than 48,000 frequency transforms per second,
transients as brief as 31 μs are displayed in the frequency domain. This is orders of
magnitude faster than conventional analysis techniques. Events are color coded
by rate of occurrence onto a bitmapped display, providing unparalleled insight into
transient signal behavior.
Trigger
The optional Frequency Mask Trigger (FMT) makes it easy to trigger on signals in the
frequency domain and capture transient signals in bandwidths up to 36 MHz. The
FMT is simply configured to monitor all changes in frequency occupancy within the
capture bandwidth. The Power Trigger, working in any capture bandwidth, fires at
the instant in time when the RF input signal crosses a user-set power threshold. An
external trigger is available for synchronization to test system events.
Capture
Unlike many SA/VSA combination instruments, the RTSA is fully preselected at all
times for spurious and image rejection in any combination of capture bandwidth
and frequency. Capture of small signals in the presence of large signals is enabled
with up to 73 dB Spurious Free Dynamic Range (SFDR) and class-leading image
rejection in all capture bandwidths. Capture once with seamless acquisitions and
make multiple measurements without recapturing. Record lengths vary depending
upon the selected capture bandwidth: up to 1.28 seconds at 36 MHz, 2.56 seconds
at 15 MHz, 51.2 seconds at 1 MHz, or 1.42 hours at 10 kHz bandwidth with optional
FMT / Deep Memory.
