How Not to be Confused by S-Parameters

By Eric Bogatin

S-parameters have a rich mathematical formalism in which there is no ambiguity. But when it comes to translating the mathematics of S-parameters into the practical interpretation of an interconnect’s electrical properties, confusion can slip in by way of an inexperienced user spreading misconceptions to a new user not sure what is important and what is not. In this article, Eric reveals seven features of S-parameters that are confusing and how not to be confused.

Ensuring High Signal Quality in PCIe Gen3 Channels

By Anil Kumar Pandey

The increased data rates of today’s high-speed Input/Output (I/O) buses make maintaining transmission channel signal quality all the more challenging. One reason for the challenge is the parasitic effects that result from bus interconnects.

LXI-Digitizers Get Additional I/O Lines for Mixed-Mode Testing

Spectrum Instrumentation has extended the capabilities of its popular LXI/Ethernet-digitizers by adding a powerful mixed-mode testing option. This option is available on four different models, all featuring eight analog input channels that synchronously sample signals at rates up to 5 MS/s, 20 MS/s, 40 MS/s or 125 MS/s with 16-bit resolution.
