Rent Tektronix RSA5126B Real-Time Spectrum Analyzer, DC to 26.5 GHz
The Tektronix RSA5126B Real Time Signal Analyzer replaces conventional instruments, offering the measurement confidence and functionality you demand for everyday tasks. The RSA5126B offers industry-leading real time specifications and includes minimum signal duration for 100% probability of intercept and best real time dynamic range. With the RSA5126B, you get the functionality of a highperformance spectrum analyzer, wideband vector signal analyzer, and the unique trigger-capture-analyze capability of a real-time spectrum analyzer – all in a single package.
The Tektronix RSA5126B replaces conventional high-performance signal analyzers, offering the measurement confidence and functionality you demand for everyday tasks. A +20 dBm TOI and -151 dBm/Hz DANL at 2 GHz gives you the dynamic range you expect for challenging spectrum analysis measurements. All analysis is fully preselected and image free. You never have to compromise between dynamic range and analysis bandwidth by 'switching out the preselector'. A complete toolset of power and signal statistics measurements are standard, including Channel Power, ACLR, CCDF, Occupied Bandwidth, AM/FM/PM, and Spurious measurements. Available Phase Noise and General Purpose Modulation Analysis measurements round out the expected set of high-performance analysis tools. But, just being an excellent mid-range signal analyzer is not sufficient to meet the demands of today's hopping, transient signals. The Tektronix RSA5126B will help you to easily discover design issues that other signal analyzers may miss. The revolutionary DPX® 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. Once a problem is discovered with DPX® , the Tektronix RSA5126B Series spectrum analyzers can be set to trigger on the event, capture a contiguous time record of changing RF events, and perform time-correlated analysis in all domains. You get the functionality of a high-performance spectrum analyzer, wideband vector signal analyzer, and the unique trigger-capture-analyze capability of a realtime spectrum analyzer - all in a single package.

The patented DPX® spectrum processing engine brings live analysis of transient events to spectrum analyzers. Performing up to 292,000 frequency transforms per second, transients of a minimum event duration of 3.7 μs in length are displayed in the frequency domain. This is orders of magnitude faster than swept analysis techniques. Events can be color coded by rate of occurrence onto a bitmapped display, providing unparalleled insight into transient signal behavior. The DPX spectrum processor can be swept over the entire frequency range of the instrument, enabling broadband transient capture previously unavailable in any spectrum analyzer. In applications that require only spectral information, Opt. 200 provides gap-free spectral recording, replay, and analysis of up to 60,000 spectral traces. Spectrum recording resolution is variable from 110 µs to 6400 s per line.
Tektronix has a long history of innovative triggering capability, and the RSA Series spectrum analyzers lead the industry in triggered signal analysis. The RSA5126B provides unique triggers essential for troubleshooting modern digitally implemented RF systems. Includes time-qualified power, runt, density, frequency, and frequency mask triggers. Time qualification can be applied to any internal trigger source, enabling capture of ‘the short pulse’ or ‘the long pulse’ in a pulse train, or, when applied to the Frequency Mask Trigger, only triggering when a frequency domain event lasts for a specified time. Runt triggers capture troublesome infrequent pulses that either turn on or turn off to an incorrect level, greatly reducing time to fault. DPX Density™ Trigger works on the measured frequency of occurrence or density of the DPX display. The unique Trigger On This™ function allows the user to simply point at the signal of interest on the DPX display, and a trigger level is automatically set to trigger slightly below the measured density level. You can capture low-level signals in the presence of high-level signals at the click of a button. The Frequency Mask Trigger (FMT) is easily configured to monitor all changes in frequency occupancy within the acquisition bandwidth. A Power Trigger working in the time domain can be armed to monitor for a user-set power threshold. Resolution bandwidths may be used with the power trigger for band limiting and noise reduction. Two external triggers are available for synchronization to test system events.
Capture once – make multiple measurements without recapturing. All signals in an acquisition bandwidth are recorded into the RSA5126B deep memory. Record lengths vary depending upon the selected acquisition bandwidth – up to 7.15 seconds at 110 MHz, 343 seconds at 1 MHz, or 6.1 hours at 10 kHz bandwidth with Memory Extension (Opt. 53). Real-time capture of small signals in the presence of large signals is enabled with 73 dB SFDR in all acquisition bandwidths, even up to 110 MHz (Opt. 110). Acquisitions of any length can stored in MATLAB™ Level 5 format for offline analysis. Most spectrum analyzers in the market utilize narrowband tunable band pass filters, often YIG tuned filters (YTF) to serve as a preselector. These filters provide image rejection and improve spurious performance in swept applications by limiting the number of signals present at the first mixing stage. YTF's are narrow band devices by nature and are usually limited to bandwidths less than 50 MHz. These analyzers bypass the input filter when performing wideband analysis, leaving them susceptible to image responses when operating in modes where wideband analysis is required such as for real time signal analysis. Unlike spectrum analyzers with YTF's, Tektronix Real Time Signal Analyzers use a wideband image-free architecture guaranteeing that signals at frequencies outside of the band to which the instrument is tuned don't create spurious or image responses. This image-free response is due to a series of input filters designed such that all image responses are suppressed. The input filters are overlapped by greater than the widest acquisition bandwidth, ensuring that full-bandwidth acquisitions are always available. This series of filters serves the purpose of the preselector used by other spectrum analyzers, but has the benefit of always being on while still providing the image-free response in all instrument bandwidth settings and at all frequencies.
The RSA5126B offers 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, or spectrum management. In addition to spectrum analysis, spectrograms display both frequency and amplitude changes over time. Time-correlated measurements can be made across the frequency, phase, amplitude, and modulation domains. This is ideal for signal analysis that includes frequency hopping, pulse characteristics, modulation switching, settling time, bandwidth changes, and intermittent signals.
