The TIA line of fiber optic oscilloscope probes(o/e converters) is an idea tool for the laboratory and the field.The 500 and 950 series have BNC outputs for direct connection to your oscilloscope or digitizer. The 1200 uses a type K SMA output connector. Free space o/e converters are available. Patch cords and adapters can be supplied to mate with various fiber optic connectors.
