For EMI testing, the use of Time Domain Scan greatly reduces measurement time without compromising accuracy. The "Comparison of Time Domain Scans and Stepped Frequency Scans in EMI Test Receivers" paper takes a critical look at the technology and its advantages. We'll compare measurement speed and level measurement accuracy of a conventional stepped frequency scan versus an advanced FFT-based time domain scan and discuss how to choose the right measurement tool for CISPR and MIL-STD testing.
Massive MIMO and beamforming in 5G base stations impose stringent requirements on ADC and DAC sampling clocks and the LO signals in 5G base stations. This video demonstrates a clock generator and an RF synthesizer from IDT and shows the measurement of the phase noise, contributed by these components.
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 is now just as important to system development as SerDes testing and the challenges presented require a higher level of test and measurement performance than ever before. This paper investigates the evaluation complexities of PAM-4 interconnects at high data rates.
With an analysis bandwidth of 400 MHz, an outstanding phase noise of -120 dBc/Hz, and a high dynamic range - the R&S®FSVA3000 signal and spectrum analyzer has everything needed to keep up with demanding measurement applications such as 5G NR. With its high measurement speed and easy usability, it is the right instrument for demanding signal analysis tasks both in the lab and on a production line.
