Picotest Introduces New Family of Signal Injectors

Picotest has released a new family of signal injectors. The signal injectors, or adapters, are designed to improve voltage regulator, LDO, and power supply testing accuracy. Increased bandwidth and higher resolution measurements are enabled for PSRR, stability, crosstalk, reverse transfer, input impedance, Bode plots, and crosstalk tests along with non-invasive in-circuit testing for load transients, stability and output impedance.

The signal injectors work with network analyzers, oscilloscopes, and arbitrary waveform generators from various manufacturers.

The family consists of two injection transformers, a DC bias injector, a line injector, a solid state voltage injector, and a unique solid state current injector along with cascadable attenuators.

The signal injectors enable high-resolution measurements to be made.

“Engineers currently connect their expensive network analyzers to DUTs (devices under test) via poor performing test adapters, such as audio, video, or 60Hz transformers or home-brewed interconnect schemes," says Steve Sandler, managing director of Picotest.com. "The data they get is often erroneous. In many cases, the data may look reasonable, but is not accurate. Much of what we find in the data sheet graphs is either incorrect or incomplete. The signal injectors solve these problems and allow analyzers and oscilloscopes to make higher resolution, higher bandwidth measurements to the point where the true circuit performance can be revealed.”

One of the key benefits is that load step, stability, and impedance measurements can all be made non-invasively while connected to hardware that is already integrated in its production form.
