Basics of Modern Signal Generators

 

In this session, the fundamental concept of an RF and microwave generator will be discussed.

The attendee will learn how a signal with a constant output power is generated. Related to the concept of a modern signal generator, typical specifications as well as the realization of fundamental analog modulations will be discussed.

 

The following topics are covered:

 

►  Fundamental synthesizer concepts of RF and microwave generators

    How to achieve low phase noise and high output power

    Fundamental specifications of RF and microwave generators

    Principles of analog and pulse modulations

Advanced Methods of Modern Signal Generators

 

Setting a frequency on a signal generator should always be fast and accurate. This workshop will look at different synthesizer concepts fulfilling this task. The attendee will learn about the advantages and disadvantages of YIG- and VCO-based synthesizers.

To set a specific low output power on a signal generator, an internal step attenuator is normally used, which should again be fast and accurate. Two different concepts will be shown in detail – the mechanical and the electronic step attenuator – as well as their advantages and limitations.

 

The following topics are covered:

 

    Advanced synthesizer concepts of  RF and microwave generators

    Comparison of YIG-based and VCO-based synthesizers

    Challenges involved in low phase noise and high output power

    High-performance analog and pulse modulations

Modern way of generating millimeter-waves from 50 GHz to 110 GHz

 

Generating millimeter waves with traditional frequency multipliers is not an easy task. The setup normally requires a signal generator, a frequency multiplier, a power meter and an external attenuator. Power calibration must be carried out for each frequency that is used. Modern frequency multipliers operate differently. They offer built-in attenuators and can be directly controlled from the front panel of the signal generator. Since the entire setup acts as a single instrument, generating accurate millimeter waves up to 110 GHz is very easy. This workshop shows how to save time and space on the workbench and avoid measurement errors by using the frequency multipliers available today.

 

 

Wednesday 9th October, 10:00 – 10:45

Easy and precise phase noise measurement using advanced spectrum analyzers

 

In this session, the fundamental concepts and ideas of measuring phase noise parameters on a wide range of devices under test (VCXO, OCXO, etc.) will be introduced and demonstrated using a state-of-the-art signal and spectrum analyzer in combination with the dedicated phase noise measurement application.

The combination of an analyzer with a very good internal reference signal source, high-performance analog-to-digital converters and signal processing, and sophisticated algorithms generates a measurement tool for all needs of modern phase noise measurement.

 

The following topics are covered:

 

    Fundamental concepts of RF and digital processing concerning phase noise

    All results at a glance – state-of-the-art user interfaces

    Special phase noise measurement functions – spot noise, residuals, spurs, limits

    Digital PLL, monitoring and tracking fast-drifting devices

 

 

Wednesday 9th October, 11:30 – 12:15

Realtime extension of high-end spectrum analyzers to 160 MHz as powerful tool for monitoring and R&D applications

 

Interference caused by sporadic and brief events in the frequency range, spectral behavior of signal sources during frequency changeovers, digital circuits that affect RF signals – these are problems that are all too familiar to developers in the field of RF engineering. Using realtime mode, advanced signal and spectrum analyzers seamlessly record RF signals with a bandwidth of up to 160 MHz, convert them into the frequency domain and display them as a spectrum. Since all the data captured is processed in realtime without any gaps, users do not miss even very short intermittent signals. With more than 200 000 spectra every second, events as short as a few µs can be detected with true power reading. This workshop will describe typical realtime applications in radar or wireless communications.

 

The following topics are covered:

    Details of realtime processing including realtime spectrum displays

    Probability of intercept (POI) for identifying brief intermittent events

    Scalable resolution bandwidth by scalable FFT length

    Frequency mask trigger for detecting sporadic signals in the frequency domain

 

 

Wednesday 9th October, 13:30 – 14:00

Extending the frequency range of spectrum analyzers by external harmonic mixing for measurement of radio links in the E-band

 

As data rates of new services increase, network operators are building up radio links in the E‑band at around 80 GHz. At these frequencies, network operators have the freedom to use bandwidths in the GHz range. However, the spectra have to follow a predefined spectrum emission mask, and the emitted power and modulation quality have to be measured. For these applications, signal and spectrum analyzers are normally used in combination with external mixers. An image-free frequency range of more than 2 GHz is needed, especially for analyzing wideband signals.

 

The following topics are covered:

    External harmonic mixing up to 90 GHz

    Image-free frequency range of 2.6 GHz

    Vector signal analysis of signals with 250 MHz bandwidth

 

 

Wednesday 9th October, 14:30 – 15:15

320 MHz analysis bandwidth for wideband applications such as pulse analysis for radar signals or multicarrier group delay measurement for satellite communications 

 

A demodulation bandwidth of 320 MHz makes today’s high-end signal and spectrum analyzers a powerful tool for wideband applications such as the analysis of very small pulses in the ns range. A dedicated pulse measurement option greatly simplifies all elements of pulse characterizations such as rise and fall time, droop, pulse width, duty cycle, settling time and pulse-to-pulse trending.

Another wideband application is the measurement of group delay utilizing a multicarrier CW signal for calibration and group delay measurement. This is a critical specification, for example, in satellite communications terminals. The necessary option now enables engineers and technicians to perform this measurement easily with minimal external hardware and calibration steps, using a spectrum analyzer instead of a vector network analyzer for a 320 MHz wide channel.

 

The following topics are covered:

    Demodulation bandwidth of 320 MHz for:

    Pulse analysis for evaluating the performance of radar systems

    Multicarrier group delay measurement for characterizing transmission path quality

 

 

Wednesday 9th October, 16:00 – 17:00

Calibrating and verifying network analyzers – How to achieve reliable measurement results

 

For many users, calibration (to be more precise: system error correction) of network analyzers is a mystery. Selecting the optimal calibration method, defining the calibration standard and doing the calibration are always potential sources of error. And after calibration, the question users are faced with is: What degree of accuracy was actually achieved using the specified parameters? The workshop describes individual calibration methods; Rohde & Schwarz network analyzers offer the widest range of possibilities. In addition, ways to verify accuracy will be discussed.

 

 

Thursday 10th October, 10:00 – 10:45

Noise figure measurement of non-frequency-converting and frequency-converting components using the internal standard measurement receiver of vector network analyzer

 

Noise figure is a key figure of merit for low-noise amplifiers and low-noise receiver frontends. Noise figure results are utilized along with S-parameters, compression characteristics and intermodulation performance during all phases of design, verification testing, and device production to enable optimal engineering decisions focused on performance vs. cost vs. yield.

 

This workshop shows how to perform frequency- and non-frequency-converting noise-figure measurements by using the standard measurement receivers of a high-end vector network analyzer. It also shows the impact of the system error correction on the measurement results.

 

 

Thursday 10th October, 11:30 – 12:15

Group delay measurements of mixers with embedded LO and without the need of a reference mixer

 

Mixers are one of the fundamental components of many receivers and transmitters, especially in the microwave range. Any mixer-based receive or transmit system requires that the mixers have well-controlled amplitude, phase and group delay responses. Especially phase and group delay linearity are essential for low bit error rates (BER) of data transmission in wireless and satellite communications systems or high target resolution for phased array antenna modules of surveillance systems.

 

In particular for satellite applications, it is difficult to perform absolute group delay measurements because of the requirement for a reference mixer.

 

This workshop will show how to measure the absolute group delay of mixers by using a vector network analyzer without the need of a reference mixer.
