Network analyzers measure network parameters of electrical networks, such as two-port amplifiers and filters. The instruments characteristically operate at 5 Hz to 1.05 THz, mostly at the higher end, though some models are sensitive down to 1 Hz. These instruments are available in two varieties: scalar network analyzers, which measure only the amplitude of the […]

Digital modulation basics, part 1
Mobile devices have evolved from basic analog phones to digitally enabled smartphones that fit in the palm of your hand. Voice communications are still part of the mix, but voice calls are handled by converting the voice signal from analog to digital and transmitting it digitally. This means that mobile wireless systems are focused on…
DesignCon video: Oscilloscopes and DDR5
At DesignCon 2020, Keysight Technologies demonstrated hardware and software products for signal integrity design and test. Keysight manufactures many oscilloscopes. While most are real-time oscilloscopes, the company also manufactures equivalent-time sampling models used for measurement and analysis of serial data streams. Here, Director Strategic Planning – Internet Infrastructure Brig Asay explains the difference between the…
Massive MIMO performance testing: Emulate the channel
Today’s 5G system capacity requirements created the need for massive multiple-input multiple-output (MIMO) systems. Massive MIMO represents a major addition to 5G. Massive MIMO enables dynamic user-focused transmission and spatial multi-user MIMO (MU-MIMO), an essential functionality for providing high data rates over large areas. Figure 1 shows how cellular applications have changed. Sub-6 GHz massive…
Scope software allows timing phase noise, jitter performance assessments
A collaboration between Keysight Technologies and Silicon Labs streamlines the validation of timing solutions critical in the development of system-level designs for wireless communications, high-speed digital, medical imaging and automotive applications. Timing plays a key role in the smooth transfer of data in wireless and wireline networks and relies on highly accurate clocks. Easy access […]
Test setup handles next-generation DDR5 memory
The world’s first design and test workflow solution designed to reduce product development time for Double-Data Rate Dynamic Random-Access Memory (DDR5 DRAM) systems has been developed by Keysight Technologies. Running at twice the data rate of DDR4, DDR5 DRAM shrinks design margins and makes it difficult for a hardware designer to optimize the printed circuit […]
