The T750 is a compact 4-channel high-voltage pulse driver. Each channel includes an input comparator and a transformer-coupled high-voltage power output stage. Output pulses follow the logic inputs and are processed by an adaptive pulse width limiter that prevents output transformer saturation.

Highland Technology also offers the T760, a dual-channel compact high-voltage driver with fiberoptic inputs.

FUNCTION 4-channel, general-purpose, isolated high voltage pulse driver
INPUTS Four single-ended, positive pulse inputs
+5 Volts max
50 Ω terminations
+1.0 V minimum usable input
Common threshold trimpot, comparator level +0.25 to +2.0 V
Threshold-set test point is provided
OUTPUTS Four individually-isolated transformer-coupled positive pulses
Common amplitude adjustment, +5.0 to +100.0 volts into an external 50 Ω load
Amplitude set test point is provided
Output is inherently low impedance and should be terminated in 50 Ω to maintain proper pulse shapes

Min pulse width 8 ns
RISETIME 4 ns max, 3 ns typ.
FALLTIME See manual section 4.5
JITTER Less than 25 ps RMS
INSERTION DELAY 8 ns nominal
POWER +12 volts, 0. 8 amps max
Highland J12 wall-plug is supplied
CONNECTORS Signals: SMB; optional SMA
Power, 2.5 mm coaxial, center positive
Tip jacks monitor for high voltage output level
Tip jacks monitor trigger threshold level
