T760 dual-channel compact high voltage optical-to-electrical converter

High Voltage O/E Converter - T760
  • Two transformer-isolated digital pulse outputs
  • Adjustable pulse amplitudes from 5 volts to 80 volts (-1 version) or 100 volts (-2 version) into 50 Ω
  • Outputs clean, flat pulses with typical risetimes below 1 nanosecond (-1 version) or 2.5 nanoseconds (-2 version)
  • Two 850 nanometer fiberoptic inputs with analog signal monitors and adjustable trigger thresholds
  • External universal power supply or 12-volt DC power
  • Compatible with Highland J720, J724, V720, and P730 optical pulse sources
  • Ideal accessory for Highland’s P400 and T560 digital delay/pulse generators, and the T34x family of embedded waveform generators

The T760 converts two digital fiberoptic inputs into high-level isolated electrical pulse outputs. Each optical input has an individual digital threshold trimpot, analog signal monitor, and threshold test point, allowing optimum setting of receive thresholds.

Digital outputs are transformer isolated. A single trimpot, with test point, sets the digital output levels from 5 volts to 80-100 volts peak.

Electrical outputs directly follow optical inputs.

Highland also offers the T750, a 4-channel high-voltage transformer-isolated pulse driver.
