RSA3408A Real-Time Spectrum Analyser
Features & Benefits• Exclusive 36 MHz Frequency Mask Trigger makes easy event-based capture of transient, pulsed, or intermittent RF signals by triggering on any change in the frequency domain• All signals up to 36 MHz spans seamlessly captured into memory • Up to 1.28 s record length at 36 MHz span provides for complete analysis over time without making multiple acquisitions • Time-correlated, simultaneous views of frequency, time and modulation domains provide a unique understanding of time-varying RF signals • Up to 20 nsec resolution Spectrogram enabling engineers to view signal instabilities and transients that they never knew existed • Built-in 802.11a/b/g application provides robust analysis of WLAN modules and systems • High 3G measurement versatility with W-CDMA, CDMA2000, 1X EVDO, HSDPA, TD-SCDMA RF and modulation analysis • Comprehensive pulsed RF signal characterization suite – makes quick work of understanding behaviour of individual pulses or a pulse train for radar and other pulsed signal analysis • General purpose digital modulation analysis, WLAN and Cellular Standards modulation analysis applications provide vector signal analyser functionality • Spectrum Analyzer view for traditional wide band signal analysis Applications• System integration on WLAN, multi-channel Wireless, WLAN/Wireless combination devices• Radar and other pulsed RF signal characterisation • RFID system development and troubleshooting (see a case study for RFID communication between reader/writer) • Characterisation of interfering or unknown signals such as in spectrum monitoring and surveillance • Diagnostic testing during component or module development, or at system integration • Getting answers to elusive EMI problems • Analog and digital modulation analysis (vector signal analysis) TriggerUnparalleled 36 MHz bandwidth Frequency Mask Trigger (FMT) makes it easy to capture transient, low duty-cycle or other difficult signals. An FMT mask is simply configured using a mouse and it can be set up for one or many frequency bands within an analysis span. FMT can monitor for signal appearance/disappearance, or change in amplitude, frequency, bandwidth, spectral shape, and more...all while the instrument user is working on another task. A Power Trigger, working in the time domain and at any real-time analysis span, can be armed to monitor for a user-set power threshold to be crossed during a moment in time. A power detector determines total power of all signals in a span which is compared to the user-set threshold. CaptureCapture once and make multiple measurements as needed. All signals in a real-time analysis span - including transients, low duty-cycle and other difficult-to-measure events - are captured together into RSA3408A deep memory where signal data can be accessed at the user's convenience for different analyses. Record lengths vary depending on span selected - up to 1.28 seconds at 36 MHz span, 51.2 seconds at 1 MHz span, or 5120 seconds at 10 kHz span with Deep Memory Option 02. Real-time capture of small signals is enhanced by –78 dBc third order IM and 66 dB 3GPP ACLR (TM1, 16 channel), plus very good phase noise performance and sensitivity. A solid performance front-end serves not only Real-Time and wide band Spectrum Analysis modes, but also on-board vector signal analysis functionality. AnalyseTime-correlated multi-domain analysis provides engineers with unique insight to time-varying signal behavior resulting in fast analysis and problem solving. Time-correlated measurements can be made across the frequency, time and modulation domains. Spectrogram with up to 20 nsec resolution provides an intuitive view of signal or spectrum changes over continuous time - immediately assess behavior of frequency hopping or pulsed signals, modulation switching, settling, bandwidth changes, relative timing of appearing and disappearing signals. The RSA3408A introduces analysis capabilities that advance productivity for engineers working on components or in RF system design, integration and performance verification, or operations engineers working in networks, spectrum monitoring, or surveillance.

See signals and events you've been missing with conventional analysis tools. With only a single acquisition, the RSA3408A Real-Time Spectrum Analyser (RTSA) provides a continuous time record of changing events in an RF spectrum and time-correlated analysis in the frequency, time and modulation domains. You get the functionality of a vector signal analyser, a wide band spectrum analyzer, plus the unique trigger-capture-analyse capability of RTSA, all in one, transportable package.
