Picotest Signal Injectors
The Picotest line of signal injectors is the most versatile and sophisticated set of test adapters ever developed. They are an essential part of getting the most out of your network and impedance analyzers whether you are measuring power supplies, regulators, other linear circuitry or components.
Our signal injectors outperform the competition with greater bandwidth, lower distortion and flat out better performance. Unique to the product line are two solid state injectors (voltage and current) and a line injection adapter ideal for measuring PSRR. The Picotest line of signal injectors can be used with any manufacturers test equipment.
