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 d esign issues that

other signal an alyzers miss. The revolutionary DPX Live RF spectrum

display offers an in tuitive live color view of sign al transients changing over

time in th

e 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-co

rrelated 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 capa bility of a R eal Time Spectrum

Analyzer – all in a single packa ge.

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 p roduct comes backed

by a one

Discover

The DPX™ spectrum processing engin e 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

freque

ncy domain and capture transient signals in bandwidths up to 36 MHz. The

FMTissimplyconﬁgured to monitor all changes in frequency occupancy within the

capture bandwidth. The Power Trigger, working in any capture bandwidth, ﬁres at

the ins

tant 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.
