Tektronix, Inc. Optical Analyzer SD48

The SD48 is an optical analyzer from Tektronix. An optical spectrum analyzer, also called an optical analyzer, is a precision instrument that measures the power of an optical source. This electronic test equipment is for monitoring power distribution over a specified wavelength span. It displays the measurement in a graph, where power is the vertical scale and wavelength is the horizontal scale. Additional Features: Wavelength: 950 to 1650 nm Bandwidth: DC to 30.0 GHz Impulse Response (FWHM): 15 ps (typ) Noise Equivalent: 15 pW per Hz Maximum Non-Destructive Power Peak Power: 100 mW Average Power: 5 mW Aberrations: 20% p-p Conversion Gain: 15 mV/mW Output Impedance: 50 ω Environmental and Physical Specifications Operating Temperature Range: 10° C to 40° C Internal Fiber Size: 9 μm Optical Return Loss: 30 dB Output Connector Style: K (2.92 mm) Applications High Speed Optical Communication Testing (SONET/SDH) Optical Source and Device Characterization Pulse Shape Analysis Analyze Relaxation Oscillation The SD-48 is an optical- to-electrical (O/E) converter for use with the Tektronix CSA 803 and 11800 Series sampling oscilloscopes equipped with an SD-2x or SD-3x Electrical Sampling Head. The SD-48 Optical-to-Electrica l Converter can be plugged directly into a 11800 sampling slot or CSA 803 power slot. Optical signal input on the SD-48 is a standard FC/PC fiber optic connector. Other connector types can be accommodated by using optional hybrid fiber optic jumper cables (SD-42) or an assortment of hybrid mating adapters which are standard with the SD-48. The SD-48 can operate as a standalone, wide-bandwidth optical-to-electrica l converter with an optional power supply (016-1609-00). These optical-to-electrica l converters can be used with Tektronix oscilloscopes or other instrumentation (e.g., spectrum analyzers). These easy to use O/E converters can be used in support of frequency and time domain analysis of lightwave modulation in optical fiber based products and communications systems. 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.
