Highland Technology (San Francisco, CA) has introduced the T750 and T760 high-voltage pulse drivers. Both feature fast, low-jitter, transformer-isolated pulse outputs which are user adjustable from +5 volts to +100 volts into a 50 ohm load, with rise and fall times typically 2ns. The T750 features four channels, each with a logic-level input and an isolated HV pulse output. The T760 has two channels, each with fiber optic inputs and isolated HV electrical outputs. Both units are packaged in compact extruded aluminum cases and are powered by an external 12-volt plug-in supply.
