The Essential Signal Generator Guide Building a Solid Foundation in RF – Part 1

Choosing the right signal generator is essential for obtaining trustworthy test results and accelerating time-to-market. This paper covers the basic functionalities, types, and key specifications of signal generators in detail. Signal generators are crucial in eliminating uncertainties in test results for engineers working on consumer electronics, wireless communications, or radar devices. They provide precise and stable test signals necessary for characterizing devices, even in bandwidth-limited and interference-heavy environments. By allowing engineers to apply impairments, signal generators help test designs within and beyond their limits, ensuring reliability and robustness. RF signal generators, including analog and vector types, create necessary waveforms for testing RF applications. Engineers use them to generate repeated or non-repeated waveforms for designing, testing, and manufacturing systems and components. Signal generators simulate real-world signals, enabling comprehensive evaluation of electronic systems’ performance and behavior.

Everything You Need to Know About Wi-Fi 7

The IEEE 802.11be standard introduces several new features for improving WLAN efficiency, capacity, and coverage. Features such as multi-link operation (MLO) and multiple resource units (multi-RUs) increase the number of configurations and test scenarios to validate a device thoroughly. In addition to physical-layer testing, test engineers must emulate signaling to verify interactions between access points (APs) and stations (STAs) and the performance of Wi-Fi 7 new features under real-world conditions. Read the white paper to explore the key features and testing challenges of Wi-Fi 7 (IEEE 802.11 be) and learn how to conduct Wi-Fi 7 RF testing with signaling and throughput testing.

TDECQ Part 1: Making Accurate and Repeatable Compliance Measurements

TDECQ is the acronym used to describe “transmitter dispersion and eye closure quaternary”. This is a power penalty metric that describes how much extra power is required from a transmitter, relative to an ideal transmitter, to compensate for both non-ideal transmitter waveforms and the impact of chromatic dispersion. It is similar to the transmitter dispersion penalty (TDP) metric used in NRZ optical communications standards. It was developed in the IEEE 802.3bs standard and improved in the IEEE 802.3cd standard. It is a convenient way to specify the performance of a PAM4 transmitter, as it aggregates many transmitter attributes into a single metric, and the metric directly indicates the impact a transmitter’s imperfections will have on overall system-level performance.
