Integrated real-time solutions


SPECMON-Series-Spectrum-Analyzers-Datasheet



Advanced Triggers and Swept DPX re-invents the way swept spectrum analysis is done. The DPX engine collects hundreds of thousands of spectrums per second over a 165 MHz bandwidth. Users can sweep the DPX across the full input range of the SPECMONB Series, up to 26.5 GHz. In the time a traditional spectrum analyzer has captured one spectrum, the SPECMONB 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.

SPECMON-Series-Spectrum-Analyzers-Datasheet



Advanced Triggers, Swept DPX, and Zero Span provides superior swept spectrum analysis for transient signals. Here, a 150 MHz swath of spectrum is swept across the ISM band. Multiple WLAN signals are seen, and narrow signals seen in the blue peak-hold trace are Bluetooth access probes. Multiple interfering signals are seen below the analyzers noise level in the multi-color DPX display.

SPECMON-Series-Spectrum-Analyzers-Datasheet



DPX Spectrograms provide gap-free spectral monitoring for up to 12 years at a time. 60,000 traces can be recorded and reviewed, with resolution per line adjustable from 125 µs to 6400 s.

Discover

The patented DPX®spectrum processing engine brings live analysis of transient events to spectrum analyzers. Performing up to 3,125,000 frequency transforms per second, transients of a minimum event duration of 0.434 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, DPX spectograms provides gap-free spectral recording, replay, and analysis of up to 60,000 spectral traces. Spectrum recording resolution is variable from 125 µs to 6400 s per line.

Trigger

Tektronix has a long history of innovative triggering capability, and the SPECMONB Series spectrum analyzers lead the industry in triggered signal analysis. The SPECMONB Series 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.


SPECMON-Series-Spectrum-Analyzers-Datasheet



Revolutionary DPX ® spectrum display reveals transient signal behavior that helps you discover instability, glitches, and interference. Here, three distinct signals can be seen. Two high-level signals of different frequency-of-occurrence are seen in light and dark blue, and a third signal beneath the center signal can also be discerned. The DPX Density™ trigger allows the user to acquire signals for analysis only when this third signal is present. Trigger On This™ has been activated, and a density measurement box is automatically opened, measuring a signal density 7.275%. Any signal density greater than the measured value will cause a trigger event.

SPECMON-Series-Spectrum-Analyzers-Datasheet



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.

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

Real-time capture of small signals in the presence of large signals is enabled with greater than 70 dB SFDR in all acquisition bandwidths, even up to 165 MHz (Opt. B16x). The dynamic range of the wideband acquisition system can be improved to an unmatched 80 dB with the options B85HD, B125HD, and B16xHD. Capture once - make multiple measurements without recapturing. All signals in an acquisition bandwidth are recorded into the SPECMONB Series deep memory. Record lengths vary depending upon the selected acquisition bandwidth - up to 5.37 seconds at 165 MHz. Acquisitions of up to 2 GB can stored in MATLAB™ Level 5 format for offline analysis.

Most spectrum analyzers use 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 achieved with 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.

Analyze

The SPECMONB 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.


SPECMON-Series-Spectrum-Analyzers-Datasheet

Here, the DPX spectrum display shows a live spectrum of the signal of interest and simultaneously provides demodulated audio to the internal instrument loudspeaker. FM deviation measurements are seen in the right side of the display for the same signal .

SPECMON-Series-Spectrum-Analyzers-Datasheet



Phase noise and jitter measurements (Opt. 11) on the SPECMONB Series may reduce the cost of your measurements by reducing the need for a dedicated phase noise tester. Outstanding phase noise across the operating range provides margin for many applications. Here, phase noise on a 13 MHz carrier is measured at -119 dBc/Hz at 10 kHz offset. The instrument phase noise of < -134 dBc/Hz at this frequency provides ample measurement margin for the task.

SPECMON-Series-Spectrum-Analyzers-Datasheet



Settling time measurements (Opt. 12) are easy and automated. The user can select measurement bandwidth, tolerance bands, reference frequency (auto or manual), and establish up to 3 tolerance bands vs. time for Pass/Fail testing. Settling time may be referenced to external or internal trigger, and from the last settled frequency or phase. In the illustration, frequency settling time for a hopped oscillator is measured from an external trigger point from the device under test.

SPECMON-Series-Spectrum-Analyzers-Datasheet


The wide-bandwidth, high dynamic range options (B85HD, B125HD, and B16xHD) offer unmatched real time spectrum analysis dynamic range. Two 16-bit, 200 MS/sec digitizers are interleaved, resulting in 400 MS/sec acquisitions with a typical spurious free dynamic range of -80 dBc, up to 10 dB better than other commercially available instruments. Here, a signal at 3 GHz is measured at -13.71 dBm, with the largest spurious signal from the digitizer -87.89 dB below the carrier.

Integrated solution for mapping

SPECMONB Series Real-Time Spectrum Analyzers provide an integrated solution for field interference and coverage problems. The built-in RSA Map lets you use an on-screen map to record the location and value of SPECMONB measurements.

With RSA Map you can do the following:

  • Select a measurement and touch the displayed map where you want the measurement to be placed
  • Use a GPS receiver (customer supplied) to automatically position measurements at your current location (on maps with geophysical reference information)
  • Collect and export measurement data (and position data when using a GPS receiver) to common formats to help analyze measurements (position, value, and direction) and prepare reports to resolve interference problems

RSA Map uses MapInfo format map files (.mif) or Windows bitmap files (.bmp) to indicate location. The .bmp format map files can be either geo-referenced or non-geo-referenced. Saved test results give you complete measurement data along with exporting compatibility to Google Earth (.kmz) and Mapinfo (MIF/MID) formats.


SPECMON-Series-Spectrum-Analyzers-Datasheet



Locate interference with azimuth direction function. It lets you draw a line or an arrow on a mapped measurement to indicate the direction your antenna was pointing when you take a measurement. User label can also be displayed (this example shows real time DPX measurement taken from Hospital, School and Park Lot)

SPECMON-Series-Spectrum-Analyzers-Datasheet



Both manual and automatic drive test measurements are supported. The Repeat measurements function automatically takes measurements at a user-set time or distance interval.
