Engineers' Insight: Selecting relays for test and measurement equipment

In test and measurement equipment, multiple factors in the path from test point to measurement point can distort the measured signal. These can include inconsistent physical connections to the signal wire; capacitances, resistances and inductances introduced into the signal path; impinging radiated and conducted electromagnetic interference (EMI); and even the signal-switching strategies in the tester.

In the new post on Engineers' Insight, Shlomo Avital examines how selecting the right relays for signal switching under test can go a long way to fixing these issues.
