The first commercial one box cathode-ray oscilloscope was launched in 1934 by General Radio (later GenRad). Read more...

Oscilloscope Probes – Vital Link in the Measurement Chain

Signal measurement results can only be as accurate as the test and measurement tools in use.  As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit.  This article looks at voltage probing considerations for embedded system and digital design debugging applications.

Precision Phase Noise Measurement with an Oscilloscope - Part 1

Often clock jitter induced from the power supply noise, signal routings, or other signals severely degrade the performance of the system. Clock generation and distribution in a FPGA for a high speed analog application is particularly prone to these issues. They manifest themselves in phase noise or clock jitter, which is the random variation of the period of a signal over time. Clearly, optimization of the design requires verification of the integrity of such clocks.
