Phase-Synchronous RF Measurements of Two Microwave Signals − New Possibilities Offered by Cross-Domain Analysis
Monday, Oct. 29, 2012 13:30 – 14:30 Click here to register
The ever increasing amount of information transmitted over RF radio links results in growing demands for detecting and handling interferences. This session presents new concepts and ideas on how to do the following:
- Detect and analyze temporary interferers
- Make EMI measurements in inconvenient ambient noise conditions
- Determine the transmission path of interferers (e.g. at electro-vehicles)
- Perform in-operation impedance analysis of a complete transmission path
In the second part of the session, some non-communications topics will be discussed, including phase-synchronous frequency monitoring techniques such as:
- Process monitoring at plasma excitation
- Process monitoring at particle accelerators
- Material research using microwaves

Frequency of Spectrum and Signal Analyzers to MM-Wave Frequencies Range
Harmonic mixers are commonly used to extend the frequency coverage of spectrum and signal analyzers to frequencies above 67 GHz. Their application is not straightforward and requires a good understanding of their working principle, their limitations and how to deal with multiple responses.
This session discusses the basic operating principle of harmonic mixers, describes ways to eliminate multiple responses and illustrates the benefits of a high intermediate frequency, as used in the R&S®FSW, for many applications.
Single-Connection Device Characterization Utilizing Vector Network Analyzers (SCDC)
The workshop explains why single-connection device characterization is required in some application fields and how users can benefit from it in general. Typical linear and nonlinear measurements performed with a vector network analyzer are described briefly, and competitive single-connection setups based on an R&S®ZVA are shown and explained. In addition, calibration issues and suitable methods are discussed.
Noise Figure Measurement with Vector Network Analyzers
Using vector network analyzers for noise figure measurements has become a powerful and flexible method to characterize active devices. There are various techniques such as the Y‑factor method which can be applied to spectrum as well as network analyzers. This workshop presents an alternative method, first introduced by Rohde & Schwarz on the R&S®ZVA and R&S®ZVT vector network analyzers. A comparison of different techniques will be made, and details on the noise figure measurement technique including the test setups will be discussed.
On-Wafer Component Testing in the Millimeter Wave Range up to 500 GHz
In cooperation with Cascade Microtech®
Wednesday, Oct. 31, 2012 10:00 – 11:30 Click here to register
As frequencies of interest expand into the millimeter wave range, more and more on-wafer component testing is required. This workshop explains measurement setups for continuous sweep up to 110 GHz and banded measurements up to 500 GHz, using the R&S®ZVA vector network analyzer in combination with R&S®ZVA-Zxxx frequency converters. The operating principle of a frequency converter is described as well as how to optimize the setup to achieve excellent measurement performance. In addition, suitable calibration techniques for on-wafer measurements will be discussed.
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
