5 Large variety of sources for signal acquisition Processing of recorded digital signal data The R&S CA210 processes recorded digital signal data from different sources: Digital I/Q data in R&S AMMOS I/Q format provided by Rohde & Schwarz monitoring receivers and direction finders; this data may be imported from a file server or from the R&S GX460/R&S GX465 recording/replay units Digital I/Q data from non Rohde & Schwarz receivers (after conversion to the R&S AMMOS I/Q format; the structure of the R&S AMMOS IF format is public); this data may be imported from a file server WAV files imported from a file server, for example (by using an included file converter) Calculation of signal-adapted spectrograms The R&S CA210 calculates a spectrogram of a recorded signal sample or wideband signal scenario sample providing a complete overview about the behaviour of the included signals. The operator can calculate several spectrograms (with different FFT lengths, window types and overlap factors may be used according to special emission types). The spectrogram is presented in a zoomable and scrollable window. Additionally, a spectrum can be activated. Selection of emissions of interest The operator selects emissions of interest and investigates them with an automatic classification algorithm or by manual measurement. Zooming to emissions of interest. Rohde & Schwarz R&S CA210 Signal Analysis Software 5 CA210_bro_en_ _v0200.indd :43:18

6 Automatic signal detection and classification for fast and reliable results Wideband signal sample investigation To speed up the investigation of a wideband signal sample that may contain a large number of different emissions, an automatic detection function is provided. The algorithm operates on a selected sample portion and delivers the time/frequency segments of all emissions matching the search criteria (such as frequency range of interest, emission power and bandwidth). Additionally a classification of the detected signal can be performed to measure the modulation parameters and determine the signals transmission system / channel code. Detected emissions listed in a table and highlighted in the spectrogram The operator can refine the detection process and edit the emission list in order to obtain a data set containing all emissions of interest. This function also enables a user to reproduce online detection results delivered by the R&S CA120 multichannel signal analysis software (for more information, see the R&S CA120 product brochure and adapt the detection parameters for difficult online search operations using the automatic detect, search and classify workflow of R&S CA120DSC. To get a complete and structured overview of the measured signals the user can filter signals with certain technical parameters. The filtered signals are highlighted in the spectrogram. A selection of detected and classified e missions is highlighted in the spectrogram. In this example all signals are highlighted with baud rates between 95 Bd and 105 Bd. 6 CA210_bro_en_ _v0200.indd :43:19

7 Automatic signal classification with complex classes of signals such as PACTOR III and STANAG 4285, this involves the identification of signal-specific characteristics such as frame structures, bit patterns and operational modes. Alternatively, pure bitstream classification is performed based on the symbol stream of a universal demodulator that is applied (e.g. FSK2 Baudot, multitone Piccolo MK12). Powerful classifier R&S CA210 includes a powerful automatic classifier for determining the modulation type, measuring technical parameters and identifying the transmission system of a wide range of analog and digital signals. For a list of all types of modulation and transmission systems that can be recognized, see the R&S CA210 data sheet. The classification algorithm performs segmentation and modulation analysis. Segmentation determines the signal's exact center frequency and bandwidth. The subsequent automatic modulation analysis determines the modulation type along with relevant modulation parameters such as symbol rate, frequency shift and number of OFDM channels. After modulation analysis has been performed, automatic transmission system recognition is initiated. E specially Using demodulators and decoders (in combination with an additional R&S CA100, installed on the same PC) If the classifier delivers a valid result, the measured modulation and transmission system parameters can be used to directly set the parameters for the demodulator/decoder in the R&S CA100 PC-based signal analysis and signal processing software (not included in the R&S CA210 delivery) so that the content can be recovered and saved. If only the type of modulation is recognized, a universal d emodulator in R&S CA100 can be used to recover a symbol stream that is saved for subsequent channel coding analysis (e.g. with R&S CA250 bitstream analysis). Information about the available demodulators and decoders is provided in the R&S CA100 brochure and data sheet. This library will be continuously expanded. Automatic classification of the technical parameters and the signal type for fixed- frequency signals. Rohde & Schwarz R&S CA210 Signal Analysis Software 7 CA210_bro_en_ _v0200.indd :43:19

8 Detailed interactive modulation analysis In-depth modulation analysis with measurement cursors in zoomable spectrogram Manual measurements of emission characteristics (bandwidth, duration, S/N ratio) can be performed with measurement cursors in the zoomable spectrogram. For in-depth measurements, the selected emission is transferred (via DDC) to high-resolution modulation analysis. The filter bandwidth is automatically adapted to filter out all disturbing out-of-band emissions and noise. Technical parameters of unknown signals R&S CA210 covers the measurement methods specified in the ITU-R SM.1600 recommendation. For unknown signals, it offers a variety of representations and tools for analyzing and measuring technical parameters such as bandwidth, symbol rate, number of tones, tone spacing, shift, modulation index, length of guard interval, number of channels, signal duration, symbol valency and modulation type. For known or standardized methods (GSM, DECT, CDMA, etc.), correlation and pattern analysis techniques are available. The tools of R&S CA210 allow quick recognition of preambles, training sequences and synchronization words of known methods. Time/frequency segmentation including filtering makes multichannel methods, noncontinuous emissions (bursts) and densely occupied signal scenarios easy to handle. Methods using multiple modulation (e.g. AM FSK, FM FSK) and (coded) orthogonal frequency division multiplex ((C)OFDM) signals can be easily measured and analyzed. I/Q constellation diagrams and eye patterns are available for evaluating the measured parameters and the equalizer settings.

9 Using automatic and manual measurement together The system's interactive modulation analysis feature is the most powerful way to quickly achieve reliable modulation analysis. The automatic classification algorithm displays all its results, giving the operator access to all relevant intermediate results (including time and frequency segmentation, primary demodulation, symbol rate estimation, equalization, harmonic analysis and sampling). The operator can verify the output of the automatic classification process one step at a time and concentrate on analysis steps where the algorithmic output might need manual refinement.
