 The TIA-950 optical receiver is the optimum instrument for the laboratory or for field use. This optical receiver can be used with a wide range of oscilloscopes and digitisers to provide the utility of a convenient, easy to use fibre optic probe. This compact unit mounts directly on the BNC input of an oscilloscope. Energising the unit, the optical signal presented to it is faithfully reproduced on the CRT of the oscilloscope or digitiser.

 Applications for this instrument include: checking the output of fibre optic communication links, fibre optic computer networks, the operation of laser sources and the signal from an optical transmitter. Adaptors are available for fibre optic connector compatibility.

 Gains are switch selected and provide peak responsivity values of approx. 2000 to 20,000 volts per watt at the peak of the detector response curve. AC coupling between stages may be introduced so that weak signals in the presence of a strong DC signal may be examined.

 Electrical bandwidth of the TIA-950 exceeds 750 MHz in the low gain position and 250 MHz in the high gain position. The output stage of the TIA-950 is fully capable of driving a 50 ohm coaxial cable terminated in its characteristic impedance. The InGaAs detector covers the 900 to 1700 nm spectral region. An FC fibre optic connector comes as standard with the TIA-950.

 Powered by a 9 V battery, the TIA-950 provides true electrical isolation from power lines and ground loops.
