Early oscilloscope models were primitive by modern standards. Among the first major innovations was triggered sweep, introduced by Tektronix just in time for the post-World War Two electronics boom. This improvement in waveform imaging synchronized successive periodic waveforms to create a coherent image, based on a uniform level along the rising edge or another user-defined […]

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 […]

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 […]
