The TIA-527 Balanced Optical to Electrical Converter is a convenient battery-operated detector/amplifier ombination that mounts directly on the input of an oscilloscope, digitizer, or other readout device. With a band width of DC to 125 MHz, it accurately provides an electrical replica of the difference of two optical signals presented to its two matched InGaAs detectors. It is fully capable of driving a 50 ohm cable terminated in its characteristic load.
The TIA-527 has selectable transimpedances of 1.4 KΩ and 14 KΩ plus a post amplifier withselectable gains of 1 or 10. Thus the overall responsivity ranges from approximately 1, 000 V/W to 100, 000 V/W at the peak of the detector response curve. Interstage coupling may be switched from DC to AC to avoid saturation of the second stage in those cases where the signal of interest is combined with a relatively large DC optical componentThe TIA-527 has selectable transimpedances of 1.4 KΩ and 14 KΩ plus a post amplifier withselectable gains of 1 or 10.

Each unit is powered by a self-contained 9 V lithium battery or a universal wall mount power supply. Battery operation eliminates ground loops and the undesirable efects of conducted radiation that may be present on local power lines.
Calibration – This is a qualitative measurement device. No calibration is required or necessary.
