Revolutionary DPX spectrum display reveals transient signal behavior that helps you discover instability, glitches, and interference. Here, an infrequently occurring transient is seen in detail. The frequency of occurrence is color-graded, indicating the infrequent transient event in blue and the noise background in red. The DPX Density Trigger is activated, seen in the measurement box at the center of the screen, and Trigger On This has been activated. Any signal density greater than the selected level causes a trigger event.

High-performance Spectrum and Vector Signal Analysis, and a Lot More

The RSA6000 Series replaces conventional high-performance signal analyzers, offering the measurement confidence and functionality you demand for everyday tasks. A typical 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. The RSA6000 Series uses broadband preselection filters that are always in the signal path. 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 a high-performance signal analyzer is not sufficient to meet the demands of today’s hopping, transient signals.

The RSA6000 Series 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. This live display of transients is impossible with other signal analyzers. Once a problem is discovered with DPX, the RSA6000 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 real-time spectrum analyzer all in a single package.

Discover

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 10.3 s 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.

Trigger and Capture: The DPX Density Trigger monitors for changes in the frequency domain, and captures any violations into memory. The spectrogram display (left panel) shows frequency and amplitude changing over time. By selecting the point in time in the spectrogram where the spectrum violation triggered the DPX Density Trigger, the frequency domain view (right panel) automatically updates to show the detailed spectrum view at that precise moment in time.

Trigger

Tektronix has a long history of innovative triggering capability, and the RSA Series spectrum analyzers lead the industry in triggered signal analysis. The RSA6000 Series provides unique triggers essential for troubleshooting modern digitally implemented RF systems. Includes time-qualified power, runt, density, 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 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

Capture once make multiple measurements without recapturing. All signals in an acquisition bandwidth are recorded into the RSA6000 Series deep memory. Record lengths vary depending upon the selected acquisition bandwidth up to 1.7 seconds at 110 MHz, 81.9 seconds at 1 MHz, or 1.46 hours at 10 kHz bandwidth with FMT / Deep Memory (Opt. 02). 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).

Analyze

The RSA6000 Series 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.

The measurement capabilities of the RSA6000 Series and available options and software packages are summarized below:

Measurement Functions

The Windows XP environment makes this multidomain analysis even easier with an unlimited number of analysis windows, all time correlated, to provide deeper insight into signal behavior. A user interface that adapts to your preferences (keyboard, front panel, touchscreen, and mouse) makes learning the RSA6000 Series easy for both first-time users and experienced hands.

Time-correlated, multidomain views provide a new level of insight into design or operational problems not possible with conventional analysis solutions. Here, ACLR and Vector Modulation Quality (Opt. 21) are performed on a single acquisition, combined with the continuous monitoring of the DPX spectrum display.

Spurious search Up to 20 noncontiguous frequency regions can be defined, each with their own resolution bandwidth, video bandwidth, detector (peak, average, Quasi-peak), and limit ranges. Test results can be exported in CSV format to external programs, with up to 999 violations reported. Spectrum results are available in linear or log scale.

Advanced Signal Analysis package (Opt. 20) offers over 20 automated pulse parameter calculations on every pulse. Easily validate designs with measurements of peak power, pulse width rise time, ripple, droop, overshoot, and pulse-to-pulse phase. Gain insight into linear FM chirp quality with measurements such as Impulse Response and Phase Error. A pulse train (upper left) is seen with automatic calculation of pulse width and impulse response (lower right). A detailed view of the Impulse Response is seen in the lower left, and a DPX display monitors the spectrum on the upper right.

Phase noise and Jitter measurements (Opt. 11) adds value to your RSA6000 Series by replacing a conventional phase noise tester for many applications. Phase noise can be measured at carrier offsets up to 1 GHz, and internal phase noise is automatically reduced by optimizing acquisition bandwidths and attenuator settings for each carrier offset for maximum dynamic range. For less critical measurements, speed optimization may be applied for faster results. Typical residual phase noise of -132 dBc/Hz at 1 MHz offset, 0 GHz carrier frequency gives sufficient measurement margin for many applications.

Advanced Triggers and Swept DPX (Opt. 200) combines the revolutionary DPX Density Trigger with the ability to trigger on runt pulses and apply time qualification to any trigger. The runt trigger seen here can be used to track down nonconforming pulses in a pulse train, greatly reducing time to insight. Time qualification can be used to separate ranging pulses from higher resolution pulses in a radar signal, or trigger only on signals that remain on longer than a specified time.

Advanced Triggers and Swept DPX (Opt. 200) re-invents the way swept spectrum analysis is done. The DPX engine collects hundreds of thousands of spectrums per second over a 110 MHz bandwidth. Users can now sweep the DPX across the full input range of the RSA6000 Series, up to 20 GHz. In the time a traditional spectrum analyzer has captured one spectrum, the RSA6000 Series has captured orders of magnitude more spectrums. This new level of performance reduces the chance of missing time-interleaved and transient signals during broadband searches.
