|1MA50: Network Analysis Video Tutorials1MA50: Network Analysis Video Tutorials||13.02.2014|
Welcome to this introductory video show about the R&S® ZVA family of network analyzers. Network analysis is sometimes considered to be cumbersome and difficult to understand, a very offputting reputation for newcomers to network analyzers. To help you look at network analyzers in a different light, we have created this video series. We have intentionally refrained from explaining any theory in depth. Rather, we want to show you how to operate our analyzers for simple and useful applications. As well as just watching this video show, you can also use it as a guide and try yourself. All the operational steps shown only require a standard RF power amplifier which should be available in almost every lab. So, before we get properly started, we hope you enjoy this video show and much success in becoming familiar with network analysis in general, and our R&S products in particular.

|7BM79: I/Q Waveform File Conversion for Use with Precise Broadcast Signal Generators7BM79: I/Q Waveform File Conversion for Use with Precise Broadcast Signal Generators||03.02.2014|
I/Q waveform files contain the digital complex sample values of a radio signal. They can be synthetically computer-calculated for generating precisely defined contents, or they can represent the recording of a received live signal. The structure of these files has never been standardized, which is why so many different formats are in use today. R&S®IQ Converter and R&S®IQ Stream Extractor are programs that quickly and conveniently convert the contents of I/Q waveform files of nearly any structure into the I/Q format used by the R&S®BTC, R&S®CLG, R&S®SLG, R&S®SFU, R&S®SFE and R&S®SFE100 signal generators. This makes it possible for the signal generators to use their integrated ARB function to generate precise RF signals from nearly any I/Q waveform file.

|7BM76: Correlated Receiver Diversity Simulations with R&S®SFU7BM76: Correlated Receiver Diversity Simulations with R&S®SFU||19.10.2012|
Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each other. This results in a more robust handling of multipath signals, since a deep fade will then not affect all received signals at the same time. However, the compact dimensions of handheld devices can introduce unwanted correlation due to their dense antenna spacing. In this case, the popular diversity test setup consisting of several independent transmitters will no longer serve the needs of a realistic simulation, since correlation effects have to be taken into account here. A clever solution is to operate the R&S®SFU in split-fading mode in combination with a second transmitter. This can be another R&S®SFU, the R&S®SFE, the R&S®SFE100 or the R&S®SMU200A. In this way, two diversity signals of adjustable correlation for any common broadcast standard are coded in realtime, while their individual multipath profile is precisely specified by the extensive features of the R&S®SFU fader module.

|1EF16: Phase Noise Measurements with Spectrum Analyzers of the FSE family1EF16: Phase Noise Measurements with Spectrum Analyzers of the FSE family||18.02.2011|
In addition to frequency, power and long-term stability, short-term stability or its equivalent, phase noise, is an important characteristic of signal sources. For example, the phase noise of conversion oscillators of receivers obtained in the presence of a strong signal determines adjacent-channel sensitivity. In the case of transmitters, the phase noise of the oscillator together with the modulator characteristics is responsible for the power generated in adjacent channels. The phase noise of oscillators or synthesizers and the relevant measurements therefore play an important role in radio transmission systems.

TDMA communications systems like GSM, DCS 1800 or PCS 1900 make effective use of the frequency spectrum by assigning several subscribers to the same frequency channel. Each subscriber has access to one predefined time slot for transmitting information. With GSM eight subscribers share one frequency channel with a bandwidth of 200 kHz. In order not to disturb the other users of the 200-kHz channel it has to be ensured that, for instance, a mobile sends in the assigned time slot only and that no power is emitted by the transmitter at other times. For this reason the transmitter power is practically switched off in the transmission intervals.

Are there really power peaks that are 20 dB above the average value? Yes, there are. Ever since the introduction of digital transmission technology, it has been necessary to deal with such orders of magnitude. RF power components must be suitably dimensioned to handle the expected voltage peaks and avoid breaking down. If we can determine the crest factor, i.e. the ratio of the peak value to the average or RMS value, with sufficient accuracy (even though it can only be assessed statistically), then we will have solved the question of dimensioning power components. This Application Note is intended to help with this problem by providing some useful insights including basic formulas, some statistical background and a practical look at the limiting factors when it comes to dealing with real transmitter systems.

In digital wireless communication systems one or multiple users are assigned to a physical RF channel. With analog systems only one user per carrier is possible. Output spectrum of the transmitter has to be restricted to the assigned channel in order to avoid interference with the neighbor channels. With the switch over to digital modulation formats more user per channel are possible. They share one channel by using only part of the time for transmission (Time Division Multiplex Access, TDMA) or by coding the transmission by orthogonal sequences for distinction to other users (Code Division Multiples Access, CDMA). Beneath the restriction of modulation spectrum with TDMA systems also time behavior of the transmitted signal is critical. One reason is that in a multi-user situation only one user is allowed to transmit within his assigned time slots. Another reason is that by switching a carrier on and off spectrum of the transmitter splatters and causes additional interference in other RF channels.

|RSH01: Reproducable Noise Figure Measurement Using the Shielded Box ZA-SB10RSH01: Reproducable Noise Figure Measurement Using the Shielded Box ZA-SB10||22.01.2011|
Determining the noise figure of a component can be difficult in unshielded lab environments. Measuring small noise figures (less than 3 dB) and reproducing the results is sometimes not possible. These difficulties are caused by interference effects (electric fields) that can occur in any environment. A suitable remedy is a measurement environment able to shield the Device Under Test (DUT) against all interfering fields in the range up to 3 GHz. When used in conjunction with a spectrum analyzer and Noise Measurement Software FS-K3, the Shielded Box ZA-SB10 provides a complete noise measurement system.

Bluetooth is a universal radio interface using the license-free 2.45 GHz frequency band. It enables electronic devices to connect and communicate without connecting cables in short-range, ad hoc networks. As the SMIQ Vector Signal Generator in combination with I/Q Modulation Generator AMIQ is able to generate nearly any kind of digitally modulated signal, this combination is also an ideal signal source for Bluetooth® test signals.
|1MA135: Path Compensation for MS Fading Tests1MA135: Path Compensation for MS Fading Tests||22.01.2011|
As well as static tests, modern mobile communication standards also stipulate measurements under fading conditions, sometimes with additional white gaussian noise AWGN. Rohde & Schwarz supports these tests with the combination of the R&S®CMU200 Radio Communication Tester and the R&S®SMU200A or R&S®AMU200A Vector / Baseband Signal Generator and Fading Simulator. Applying fading and noise always raises the crest factor of a signal considerably. Thus, automatic path attenuation inside the R&S® baseband fader prevents the new signal peaks from being clipped at I/Q full scale. Any additional attenuation in the baseband, however, makes the RF output fall below its intended level. This application note shows how to achieve an accurate RF output level by compensating for the I/Q attenuation - without modifying the test setup or using additional instruments.
|1EE13: Radiomonitoring with Test Receivers R&S®ESN/ESVN1EE13: Radiomonitoring with Test Receivers R&S®ESN/ESVN||22.01.2011|

|1EE19: Exchanging Data Records between Different Test Receiver Models1EE19: Exchanging Data Records between Different Test Receiver Models||22.01.2011|
Rohde & Schwarz test receivers of the ESXS, ESS and ESXN series are equipped with a 3.5' floppy-disk drive so that receiver settings, scan results, limit lines, transducer factors and whole sets of transducers can be stored on a floppy disk and reloaded into the receiver. Data can only be loaded into the receiver type from which they have been stored. The reason is that data eg from an ESHS30, which operates in the frequency range from 9 kHz to 30 Hz, should not be loaded into an ESVS30 as the data of the two units may be incompatible to because of the different frequency ranges alone (ESVS30: 20 MHz to 1000 MHz). However, in some cases it may be desirable to load an ESVS20 file into an ESVS30, or an ESN file into an ESVN40.

|1GPAN28: Frequency Hopping for GSM Base Station Tests with Signal Generators SME1GPAN28: Frequency Hopping for GSM Base Station Tests with Signal Generators SME||22.01.2011|
While Mobile phones are allowed to require approximately 3 time slots for switching from transmission to reception, base stations must be able to transmit and receive at a new frequency in every time slot in the frequency hopping mode. This behaviour must of course be tested and measurements carried out on the base station transmitter and receiver. Since there is no signal generator which is able to settle at different frequencies from one to the next time slot with GSM modulation, a solution to this problem was found by linking two Signal Generators SME in such a way that they alternately provide signals at different frequencies.
|1EZ27: Frequency Conversion Measurements with Vector Network Analyzer R&S®ZVR1EZ27: Frequency Conversion Measurements with Vector Network Analyzer R&S®ZVR||22.01.2011|
Vector Network Analyzer ZVR is able to control two external generators via the IEC/IEEE bus in the frequency conversion mode. This feature allows to make automatic measurements on DUTs with up to two frequency converters. For the measurement of the conversion response over the whole frequency range, one of the two generators must be swept. Since this frequency variation is controlled via the IEC/IEEE bus, the sweep time must be increased (automatically) depending on the used generator. Very short sweep time is possible by the use of a generator SME or SMP and the IEC+TTL remote mode. In this case the generator operates in the frequency list mode triggered by ZVR.

This application note describes how to use the Rohde & Schwarz software tool ‘RsBatchConvert.exe’ for the conversion of binary data or WinIQSIM generated AMIQ waveforms into the new waveform format. The tool not only rescales I/Q data contained in the file but also changes the K-option requirement from WinIQSIM Kxx to the new WinIQSIM2 K2xx options. Thus, new instruments with installed K2xx options may be used to continue using existing waveform files.

While RF communication signal distortions in nonlinear transmission paths have been predicted theoretically and studied experimentally for various signals, it is interesting to examine a wideband nonlinear system reaction to a wideband 3G signal and a narrowband 2G signal. Research and testing have demonstrated that, while most vital signal parameters remain within the limits specified by applicable standards even if composite signal power approaches specified maximum power, a relatively high level of spurious emissions caused by cross- and intermodulation can result. To avoid degrading both existing and new systems, this and other signal quality issues must be considered when designing and deploying multitechnology systems.
