Ransom Stephens GFM355 PAM-4 (4-level pulse amplitude modulation) has been introduced in high-speed serial data technology to reduce the bandwidth demands of ultra-high data rates. It uses only half the bandwidth per bit that would be required of conventional NRZ (non-return to zero) modulation. But at the same time, PAM-4 signaling complicates design and test at every turn. Evaluation of channels
Load pull is a powerful method for characterizing RF power amplifiers through impedance variation. Load pull enables model extraction and validation as well as performance, ruggedness and efficiency testing. Amplifier characterization, load pull, RF power amplifiers, vector network analyzers, R&S ZNA Load pull enables model extraction and validation as well as performance, ruggedness and efficiency
Thilo Bednorz 1EP83 Vector Network Analyzers of t ZNA and ZNB family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT is obtained, which gives an especially clear form of representation
The R&S®ZNA vector network analyzer with the integrated LO output option provides a simple, cost-effective solution for 2-port and 4-port measurements using Rohde & Schwarz mmWave converters. ZNA, vector network analyzer, ZC110, ZNA Compact solution for network analysis in the mmWave range Your task Extending the basic frequency range of high-end network analyzers has always been possible and was previously
Thilo Bednorz 1EZ82 Many applications in aerospace and defense as well as in mobile communication require a defined magnitude and phase relation between several signals, for example, to design a smart antenna array and it's distribution network, or to ensure accurate phase alignment between different transmitter or receiver chains of T/R modules. Magnitude can be measured with spectrum analyzers or
Thilo Bednorz 1EZ81 Frequency converters e.g. in satellite transponders need to be characterized not only in terms of amplitude transmission but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. They often do not provide access to the internal local oscillators. This application note describes a method using the R&S®ZNA analyzer family
The R&S®ZNA vector network analyzer offers a dynamic range that is unbeatable on the market. This kind of sensitivity unlocks potential applications that previously could not be addressed with a vector network analyzer. ZNA, Measure satellite output multiplexers and circulators under real conditions Your task Output multiplexers (OMUX) used in communications satellite payloads are designed to combine
