The conversion is calibrated for a gain of 25 µW/mV, when the input signal is in the 1300 nm band. Power for the Tektronix SA-42 can be provided from one of three sources: internal batteries, from the hose instrument via a probe power socket, or the power supply and charger unit provided. As the quiescent power required for the SA-42 is negligible, the batteries are permanently connected to the photodiode circuitry and are only disconnected when an external source is used. Opto-electronic devices such as laser diodes, light emitting diodes, optical waveguides, optical detectors, and electro-optic modulators is becoming more important as applications for fiber optics in telecommunications and data communications expand. These Optical-to-Electrica l Converters offer fiber optic equipment designers and researchers optical waveform measurement capability from DC to 30 GHz in the 700 nm to 1650 nm wavelength range. Measurements such as rise time, aberrations, optical power vs. drive current and voltage, modulation bandwidth, and sensitivity can now be made accurately and easily at high bandwidth.
