Developed to aid power supply designers in control-loop stability analysis, Picotest’s line of signal injectors are being introduced as the “most flexible and sophisticated injector product line ever introduced.” The product line includes the two injection transformers; the J2100A which features 1-Hz to 5-MHz bandwidth and the J2101A, which offers 10-Hz to 45-MHz bandwidth. To complement these, Picotest offers a dc- to 50-MHz solid-state signal injector (J2110A), a line injector for measuring PSRR (J2120A), a dc bias injector (J2130A), and a wideband current injector (J2111A). A set of attenuators are also available.
