The RSA306B: a new class of instrument

The RSA306B offers full-featured spectrum analysis and deep signal analysis at a price unmatched by any previous offering. Using the latest in commercial interfaces and available computing power, the RSA306B separates signal acquisition from measurement, dramatically lowering the cost of instrument hardware. Data analysis, storage and replay is performed on your personal computer, tablet or laptop. Managing the PC separately from the acquisition hardware makes computer upgrades easy, and minimizes IT management issues.

SignalVu-PC™ software and an API for deep analysis and fast programmatic interaction

The RSA306B operates with SignalVu-PC, a powerful program that is the basis of Tektronix performance signal analyzers. SignalVu-PC offers a deep analysis capability previously unavailable in value-priced solutions. Real-time processing of the DPX spectrum/spectrogram is enabled in your PC, further reducing the cost of hardware. Customers who need programmatic access to the instrument can choose either the SignalVu-PC programmatic interface or use the included application programming interface (API) that provides a rich set of commands and measurements. A MATLAB driver for the API is available, enabling operation with MATLAB and the Instrument Control Toolbox.

The RSA306B with SignalVu-PC offers basic and advanced measurements for field and lab

See what you’ve never seen before: The 40 MHz real time bandwidth of the RSA306B combined with the processing power of SignalVu-PC shows you every signal, even down to 100 μs in duration. The following image shows a WLAN transmission (green and orange), and the narrow signals that repeat across the screen are a Bluetooth access probe. The spectrogram (upper part of the screen) clearly separates these signals in time to show any signal collisions.

Monitoring has never been easier. Spectrum mask testing captures detail of transients found in the frequency domain, such as intermittent interference. Mask testing can be set to stop acquisition, save acquisition, save a picture, and send an audible alert. The following image shows a spectrum mask (in orange on the spectrum display) created to monitor a band of frequencies for violations. A single transient of 125 μs duration has occurred that violated the mask, with the violation shown in red. The transient is clearly seen on the spectrogram above the red violation area (circled).

EMI pre-compliance and diagnostic measurements are easy with the RSA306B and SignalVu-PC. Transducer, antenna, preamplifier, and cable gain/loss can be entered and stored in correction files, and the standard spurious measurement feature of SignalVu-PC can be used to establish limit lines for your test. The following illustration shows a test from 30 MHz to 1 GHz with the test limit shown in green. Violations are recorded in the results table of the test below the graph. CISPR peak detection and -6 dB filter bandwidths are standard functions, giving you comparable results to other tools.

Analysis of AM and FM signals is standard in SignalVu-PC. The following screen shot shows a 1 kHz tone amplitude modulating a carrier to 48.9% total AM. Markers are used on the spectrum display to measure the modulation sideband at 1 kHz offset, 12.28 dB down from the carrier. The same signal is simultaneously viewed in the modulation display, showing AM versus time, with +Peak, -Peak and Total AM measurements. Advanced measurements for analog audio modulation including SINAD, THD and modulation rate are available in Option SVA.

SignalVu-PC application-specific licenses

SignalVu-PC offers a wealth of application-oriented measurement and analysis licenses including:

  • General-purpose modulation analysis (27 modulation types including 16/32/64/256 QAM, QPSK, O-QPSK, GMSK, FSK, APSK)
  • P25 analysis of phase I and phase 2 signals
  • WLAN analysis of 802.11a/b/g/j/p, 802.11n, 802.11ac
  • LTE™ FDD and TDD Base Station (eNB) Cell ID & RF measurements
  • Bluetooth® analysis of Low Energy, Basic Rate and Enhanced Data Rate
  • Mapping and signal strength
  • Pulse analysis
  • AM/FM/PM/Direct Audio Measurement including SINAD, THD
  • Playback of recorded files, including complete analysis in all domains
  • Signal Classification and Survey

Modulation analysis application SVM enables multiple displays of modulation quality. The following screen shot shows the standard Channel Power/ACLR measurement combined with a constellation display and vector signal quality measurements on a QPSK signal.

SignalVu-PC application SV26 enables quick, standards-based transmitter health checks on APCO P25 signals. The following image shows a Phase II signal being monitored for anomalies with the spectrum analyzer while performing transmitter power, modulation and frequency measurements.

Sophisticated WLAN measurements are easy. On the 802.11g signal shown below, the spectrogram shows the initial pilot sequence followed by the main signal burst. The modulation is automatically detected as 64 QAM for the packet and displayed as a constellation. The data summary indicates an EVM of -33.24 dB RMS, and burst power is measured at 10.35 dBm. SignalVu-PC applications are available for 802.11a/b/j/g/p, 802.11n and 802.11ac to 40 MHz bandwidth.

With application SV27 you can perform Bluetooth SIG standard-based transmitter RF measurements in the time, frequency, and modulation domains. This application supports Basic Rate and Low Energy Transmitter measurements defined by Bluetooth SIG Test Specification RF.TS.4.1.1 for Basic Rate and RF-PHY.TS.4.1.1 for Bluetooth Low Energy. Application SV27 also automatically detects Enhanced Data Rate packets, demodulates them and provides symbol information. Data packet fields are color encoded in the Symbol table for clear identification.

Pass/Fail results are provided with customizable limits and the Bluetooth presets make the different test set-ups push-button. The measurement below shows deviation vs. time, frequency offset and drift, and a measurement summary with pass/fail results.

The SignalVu-PC MAP application enables interference hunting and location analysis. Locate interference with an azimuth function that 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. You can also create and display measurement labels.

Application SV28 enables the following LTE base station transmitter measurements:

Cell ID

Channel Power

Occupied Bandwidth

Adjacent Channel Leakage Ratio (ACLR)

Spectrum Emission Mask (SEM)

Transmitter Off Power for TDD

There are four presets to accelerate pre-compliance testing and determine the Cell ID. These presets are defined as Cell ID, ACLR, SEM, Channel Power and TDD Toff Power. The measurements follow the definition in 3GPP TS Version 12.5 and support all base station categories, including picocells and femtocells. Pass/Fail information is reported and all channel bandwidths are supported.

The Cell ID preset displays the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS) in a Constellation diagram. It also provides Frequency Error.

The ACLR preset measures the E-UTRA and the UTRA adjacent channels, with different chip rates for UTRA. ACLR also supports Noise Correction based on the noise measured when there is no input. Both ACLR and SEM will operate in swept mode (default) or in faster single acquisition (real-time) when the measurement bandwidth required is less than 40 MHz.

Playback of recorded signals can reduce hours of watching and waiting for a spectral violation to minutes at your desk reviewing recorded data. Recording length is limited only by storage media size and recording is a basic feature included in SignalVu-PC. SignalVu-PC application SV56 Playback allows for complete analysis by all SignalVu-PC measurements, including DPX Spectrogram. Minimum signal duration specifications are maintained during playback. AM/FM audio demodulation can be performed. Variable span, resolution bandwidth, analysis length, and bandwidth are all available. Frequency mask testing can be performed on recorded signals up to 40 MHz in span, with actions on mask violation including beep, stop, save trace, save picture, and save data. Portions of the playback can be selected and looped for repeat examination of signals of interest. Playback can be skip-free, or time gaps can be inserted to reduce review time. A Live Rate playback ensures fidelity of AM/FM demodulation and provides a 1:1 playback vs. actual time. Clock time of the recording is displayed in the spectrogram markers for correlation to real world events. In the illustration below, the FM band is being replayed, with a mask applied to detect spectral violations, simultaneous with listening to the FM signal at the center frequency of 92.3 MHz.

The signal classification application (SV54) enables expert systems guidance to aid the user in classifying signals. It provides graphical tools that allow you to quickly create a spectral region of interest, enabling you to classify and sort signals efficiently. The spectral profile mask, when overlaid on top of a trace, provides signal shape guidance, while frequency, bandwidth, channel number, and location are displayed allowing for quick checks. WLAN, GSM, W-CDMA, CDMA, Bluetooth standard and enhanced data rate, LTE FDD and TDD, and ATSC signals can be quickly and simply classified. Databases can be imported from your H500/RSA2500 signal database library for easy transition to the new software base.

Above is a typical signal survey. This survey is of a portion of the TV broadcast band, and 7 regions have been declared as either Permitted, Unknown, or Unauthorized, as indicated by the color bars for each region.
In this illustration, a single region has been selected. Since we have declared this to be an ATSC video signal, the spectrum mask for the ATSC signal is shown overlaid in the region. The signal is a close match to the spectrum mask, including the vestigial carrier at the lower side of the signal, characteristic of ATSC broadcasts.

SignalVu-PC with mapping can be used to manually indicate the azimuth of a measurement made in the field, greatly aiding in triangulation efforts. The addition of a smart antenna able to report its direction to SignalVu-PC automates this process. Automatically plotting the azimuth/bearing of a measurement during interference hunting can greatly speed the time spent searching for the source of interference. Tektronix offers the Alaris DF-A0047 handheld direction finding antenna with frequency coverage from 20 MHz -8.5 GHz (optional 9 kHz-20 MHz) as part of a complete interference hunting solution. Azimuth information and the selected measurement is automatically recorded on the SignalVu-PC Map just by releasing the control button on the antenna. Full specifications for the DF-A0047 antenna are available in a separate antenna datasheet available on www.Tektronix.com.
