If you see the word “arbitrary” in conjunction with a function generator, it signifies the instrument’s capability to customize waveforms at the user’s discretion. The new Tektronix AFG31000 Series arbitrary function generator incorporates this technology on top of its traditional library of a dozen basic waveforms: sine, square, ramp, pulse, noise, sin (x)/x, dc, Gaussian, […]

PCIe 4.0 U.2/U.3, M.2 interposers facilitate SSD protocol analysis
The U.2/U.3 and M.2 interposer cards help analyze both standard single-port and dual-port solid-state drives (SSDs) that support the PCI Express (PCIe) 4.0 specification. When used with the Summit Protocol Analyzer, the U.2/U.3 and M.2 Interposer Cards enable the capture and analysis of all PCIe bus traffic between a host backplane and a single- or […]
5G conformance toolset supports validated GCF and PTCRB protocol
Keysight Technologies says its 5G Conformance Toolset now supports the greatest number of validated Global Certification Forum (GCF) and PTCRB protocol, as well as radio frequency (RF) conformance test cases, for both 5G new radio (NR) non-standalone (NSA) and standalone (SA) mode, as reaffirmed at the recent GCF meeting. Protocol and RF conformance tests are […]
Optical spectrum analyzer helps size up 100G/400G optical modules
The Optical Spectrum Analyzer (OSA) MS9740B combines high-end measurement-sensitivity performance, expanded functionality, compact size, and high-speed measurement capability. With the MS9740B, design and manufacturing engineers can accurately verify and improve time-to-market of 100G/400G optical modules designed into 5G and Cloud communications systems. To improve measurement speed by 50%, Anritsu enhanced the optical receiver bandwidth settings […]
EMI receiver gets time-domain scan, real-time scan capabilities
Time Domain Scan (TDS) and Real Time Scan (RTS) capabilities have been added to the Keysight N9048B PXE Electromagnetic Interference (EMI) receiver that enable real-time measurements and diagnostics for faster electromagnetic compliance (EMC) certification. EMC testing requires detailed and exacting methodologies to ensure that all emissions are accurately measured. Long test times impact test facility […]
What you need to know about information theory
A lot of the testing and verification activities of EEs today centers on concepts having a theoretical basis in Claude Shannon’s (of Nyquist-Shannon renown) article titled, A Mathematical Theory of Communication, which appeared in 1948 in the Bell System Technical Journal. Shannon’s full treatise gets to be quite mathematical. Fortunately, some of the fundamental concepts […]
Portable power quality analyzer decodes three-phase power problems
The Hioki PQ3198 Power Quality Analyzer can be used for assessing power usage as well as for investigating power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. Hioki portable power analyzers can measure single to three-phase lines with a high degree of precision and accuracy. New features include the ability to […]
Stand-alone module facilitates testing of MIPI-enabled devices
The SV4D is a versatile, high-performance, ultra-compact test module enabling at-speed production testing for MIPI interfaces. Capable of operating independently or within any ATE load board, the SV4D is ideal for deployment at wafer sort as well as final test or system-level test. With up to 4 MIPI transmit or receive ports each containing multiple […]
