Improvements to the Cleverscope CS448 — an isolated high common-mode rejection ratio (CMRR) four-channel 200MHz 14-bit oscilloscope — let it measure high voltages – now up to 1,600 V – for fast slew-rate signals such as those in a full or three-phase power electronics switching bridge. Examples of challenging measurement tasks the CS448 can handle […]
Working with the PicoScope PC-based oscilloscope
A PC-based oscilloscope, or USB oscilloscope as it is also known, has a lot going for it. For one thing, it costs substantially less than a bench model with equivalent specifications, given that most users already own the major component. The PC or Mac provides the processing and display parts of the equation. (The computer, […]
Compact 6 GHz USB RF vector spectrum analyzer
The Triarchy Technologies VSA6G2A Vector Spectrum Analyzer is an economical tool that plugs into the USB port of a PC and is controlled with the provided PC application software. It offers almost all the functionality of a benchtop spectrum analyzer. Its frequency range of operation is from 100 Hz to 6.2 GHz, with an amplitude […]
Isolated-channel PC-based scope designed for high-common-mode slew measurements
The CS448 isolated-channel oscilloscope provides four isolated analog channels and eight digital channels. Developed by Cleverscope, it includes a 0-65-MHz isolated signal generator, USB 3, a 1-Gbit Ethernet port using an SFP socket for either wired or optical ethernet connection, and a general-purpose 16-pin mixed-signal control port using programmable hardware (a Silego SLG46533V) which includes […]
Checking out CircuitGear’s CGR-201 PC-Based Oscilloscope
The PC-based oscilloscope is a simple idea. The instrument consists of hardware and software layers. The hardware is a small module that plugs into a PC’s USB slot. The complete oscilloscope also makes use of a modern desktop computer which works in conjunction with the proprietary module. I have used two PC-based oscilloscopes, one from […]
Scope software tests USB 3.1 Type-C transmitters
Keysight Technologies, introduced the U7243B USB 3.1 Type-C transmitter performance validation and compliance test software, the most comprehensive transmitter test support for the USB 3.1 Type-C specification. The test software allows authorized test centers to test USB 3.1 Gen2 SuperSpeed Plus 10 Gbps devices with Type-C implementations and gives in-house test and performance validation engineers […]
One-slot “PXI vector network analyzers” cover 300 kHz – 26.5 GHz band
Keysight Technologies, Inc. announced a series of one-slot PXI vector network analyzers that cover 300 kHz up to 26.5 GHz. The new analyzers offer the best PXI VNA performance on key specifications such as speed, trace noise, stability and dynamic range. This enables the PXI VNAs to perform fast, accurate measurements and reduce the cost-of-test […]
RF PA/FEM Characterization & Test, Reference Solution characterizes power amps
Keysight Technologies, Inc. announced a new PXI Reference Solution for RF power amplifier (PA) characterization and test. The Reference Solution, which performs S-parameter, harmonic distortion, power and demodulation measurements, enables rapid, full characterization of next-generation power amplifier modules, such as a power amplifier-duplexer (PAD). The Reference Solution is optimized for high throughput and highly accurate […]
H-P, Agilent, Keysight: New name, same reputation
Those of us who have been around electronic instrumentation for a while can remember the days when Hewlett-Packard instruments were considered the cream of the crop. Where I worked, we always tried to get to the lab early on the days we had tests to run so we could get our hands on the highly […]
HEIDENHAINs New Portable Interface Box Eliminates Need for PC Cards
HEIDENHAIN now offers a new EIB 742 external interface box for precise position measurement. It is a network-capable measuring solution that removes the requirement of a PC interface card that is usually necessary when connecting measurement apparatus to an industrial PC or laptop. The EIB 742 is ideal for inspection stations and multipoint inspection apparatuses […]
