What to look for during instrument calibration
When you send an instrument to a calibration lab, what do you expect to happen? The comprehensive definition of calibration is a verification of instrument specifications by measuring actual performance using external lab standards, normally instruments, which have better performance than the thing they’re measuring and which are traceable to the International System of Units […]
First 256-GS/sec arbitrary waveform generator features analog bandwidth exceeding 80 GHz
The new M8199B arbitrary waveform generator (AWG) provides R&D engineers a high-performance signal source for arbitrary signals that enables development of designs employing multi-level modulation formats (e.g. 64QAM) at well beyond 160 GBaud. Applications beyond 128 GBaud demand a new class of generators that provide high speed, precision and flexibility at the same time. Keysight […]
BERT Ethernet test gear handles 224 Gbps signals
New 224G Ethernet test solutions enable system-on-a-chip (SoC) makers to validate next generation electrical interface technology, accelerating 1.6 terabit per second (1.6T) transceiver design and pathfinding. 5G, artificial intelligence (AI) and internet of things (IoT) applications are driving growth in data traffic, creating unprecedented bandwidth demands in networks and data centers. High-speed digital interfaces that […]
Test setup verifies mobile industry processor interface A-PHY layer compliance
A new automotive serializer/deserializer (SerDes) receiver (Rx) compliance test solution verifies mobile industry processor interface (MIPI) A-PHY devices based on the Compliance Test Specification (CTS) requirements. This solution was developed in collaboration with BitifEye Digital Test Solutions GMBH and Wilder Technologies, with the support of Valens Semiconductor Ltd.. Silicon vendors are planning to implement MIPI […]
Analyzing jitter with an oscilloscope
Jitter–basically the deviation between true and measured periodicity–is harmful beyond a certain level. In measuring jitter, we are calculating RMS, peak-to-peak deviation or spectral density. Jitter at frequencies below 10 Hz is known as wander. High-frequency signals are more prone to jitter than low-frequency signals. The deviation in periodicity that constitutes jitter may be in […]
The difference between impedance analyzers and network analyzers
At first glance, impedance analyzers and network analyzers seem to do the same thing: Describe the impedance of whatever is connected to their inputs. This statement is true as far as it goes, but as you might expect, there are significant differences between the two types of instruments. Here’s a review of the basics. There […]
Exceeding 100 Gbps with a sub-terahertz 6G testbed
Here’s a look at testing necessary for super-high throughputs involved in the emerging area of 6G. Greg Jue, Keysight Technologies 6G research is in its early stages. The vision for what the International Telecommunication Union calls Network 2030 continues to take shape. While the industry is years away from starting the standards development process, subterahertz […]
