Introduction
The TIA-952 Optical to Electrical Converter is a convenient
fi
ber optic detector/ampli
fi
er combination
that mounts directly on the input of an oscilloscope, digitizer, or other readout device. With a band-
width of 800 MHz, it accurately provides an electrical replica of the optical signal presented to it. It is
fully capable of driving a 50 ohm cable terminated in its characteristic load.
The InGaAs version of the TIA-952 has a transimpedance of 500
Ω
plus a post ampli
fi
er with select-
able gains of 1 or 5. Thus the overall responsivity ranges from approximately 450 V/W to 2250 V/W
at the peak of the detector response curve and when terminated in a 50 ohm load.
The Silicon version of the TIA-952 has a transimpedance of 250
Ω
plus a post ampli
fi
er with select-
able gains of 1 or 5. Thus the overall responsivity ranges from approximately 225 V/W to 1125V/W
at the peak of the detector response curve and when terminated in a 50 ohm load.
The unit is powered by a universal wall mount power supply. The supply accepts mains voltages
from 95 to 260 V.A.C., 47-60 Hz. Four mains plugs are provided that are compatible with standards
used in North America, Great Britain, Continental Europe and Australia.
Unpacking and Inspection
Prior to shipment this instrument was inspected and found to be free of mechanical and electrical
defects. Upon acceptance by the carrier he assumes responsibility for its safe arrival. After unpack-
ing, examine the unit for any evidence of shipping damage. Should you receive this instrument in a
damaged condition, apparent or concealed, it must be noted on the freight bill or express receipt and
signed by the carrier’s agent. Failure to do so could result in the carrier refusing to honor the claim.
Upon
fi
ling a claim TTI should be noti
fi
ed.
Calibration - This is a qualitative measurement device. No calibration is required or necessary
