Tektronix RSA306 USB Real-time Spectrum Analyzer Video Review

Watch this short video presentation of a USB analyzer Tektronix RSA306. It shows the functional and design features of this device and highlights its strengths: compactness, excellent performance, low price, examples of use in an outdoor laboratory in conjunction with an industrial tablet.

 

DETAILED DESCRIPTION

The Tektronix RSA306 Spectrum and Signal Analyzer is a new class instrument. It allows you to perform comprehensive spectrum analysis and in-depth analysis of impulse signals at a price that compares favorably with all known analogues. Using the latest interfaces and available computing power allows you to separate signal acquisition from its measurement, which significantly reduces the cost of equipment. Analysis, recording and playback of data is performed on your desktop computer, tablet or laptop. Operating the computer separately from the capture system makes it easy to increase processing power and minimize control problems of the measuring system.

 

The standard capabilities of this analyzer can be upgraded with a wide range of additional options (12 in total). For a complete list of extension options, see Options and accessories, as well as in the section Documentation.

 

Tektronix RSA306 Spectrum Analyzer with SignalVu-PC software performs basic and advanced measurements in the lab and in the field

With this device you will see what was previously impossible. The RSA306 real-time spectrum analyzer with 40 MHz analysis bandwidth, using the powerful computing capabilities of SignalVu-PC software, allows you to deeply investigate any signal with a duration of 100 µs. The following screenshot shows WLAN signals (green and orange) as well as Bluetooth test signals as narrowband repeating signals. The spectrogram (top of screen) clearly shows signal changes over time, making it possible to clearly identify any simultaneously transmitted signals.

 

Monitoring has never been easier with the Tektronix RSA306 Spectrum Analyzer

Spectrum mask testing allows the Tektronix RSA306 to examine in detail transients in the frequency domain, such as those associated with infrequent interference. A mask mismatch can be used as a condition to stop capturing, remember the collected data and screen image, and sound an alert. The following screenshot shows a spectrum mask (orange in the spectrum screen) created for monitoring over a given frequency range. One outlier of 125 µs duration is shown in red. This transient process is clearly visible on the spectrogram above the mask violation area marked in red (circled in red).

 

AM and FM signal analysis is standard on the Tektronix RSA306 analyzer

AM and FM signal analysis is standard on the Tektronix RSA306 analyzer with SignalVu-PC software. The following screenshot shows a carrier signal modulated with a 1 kHz tone (48.9% AM depth). The markers are used on the spectrum screen to measure the modulation sideband at a 1 kHz offset, 12.28 dB below the carrier level. Simultaneously, the same signal can be seen on the modulation screen showing the AM signal versus time with the measured positive peak, negative peak and modulation depth. Advanced analog audio modulation measurements, including SINAD, harmonic distortion, and modulation frequency, are available with the optional SVA option.

 

Tektronix RSA306 spectrum analyzer with additional options provides extensive modulated signal quality measurements

The Tektronix RSA306 Spectrum Analyzer with SignalVu-PC software offers a wide range of signal analysis options. The following screen shot shows a standard channel power measurement and adjacent-channel leakage power with optional modulation analysis to represent spectrum measurements with constellation and vector QPSK signal quality measurements.

 

Comprehensive WLAN Signal Measurements with Tektronix RSA306 with SignalVu-PC Software

Comprehensive WLAN signal measurements are made easy with the Tektronix RSA306 real-time spectrum analyzer. Below is a spectrogram of an 802.11g signal showing the initial control sequence followed by the main signal packets. The 64 QAM modulation automatically detected for a burst is displayed as a constellation diagram. The summary shows an error vector amplitude (EVM) of -33.24 dB(r.m.s.) and a burst power of 10.35 dBm. SignalVu-PC has options to measure 802.11a/b/j/g/p, 802.11n, and 802.11ac signals up to 40 MHz analysis bandwidth.

 

This video shows how the Tektronix RSA306 can be used to measure and analyze non-stationary Bluetooth wireless network signals. This clearly shows the advantages of a real-time spectrum analyzer over traditional scanning (sweeping) analyzers.

 

Search for interference sources with mapping

The MAP option for the Tektronix RSA306 analyzer with SignalVu-PC software allows you to search for interference sources and analyze their signal strength. The location of the interferer is defined as a function of azimuth. This gives you the opportunity to indicate the direction of the antenna on the map with a line or arrow based on several measurements and, thus, find the source of the signal. You can also create and display measurement labels.
