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 2-channel high-volrage driver with fiberoptic inputs |

| FUNCTION |
4 Channel, General-purpose, Isolated High Voltage Pulse Driver |
| PACKAGING |
4.0 x 4.75 x 1.25 inches extruded aluminum enclosure. |
| INPUTS |
Four single-ended, positive pulse inputs
+5 Volts max
50 ohm terminations
+1. 0 V minimum usable input
Common threshold trimpot, comparator level +0.5 to +2.5V. Threshold-set test point is provided.
|
| OUTPUT |
Four individually-isolated transformer-coupled positive pulses
Common amplitude adjustment trimpot, +5.0 to +100.0 volts to an external 50 ohm load. HV set test point is provided. Output is inherently low impedance so should be terminated in 50 ohms to maintain proper pulse shapes.
Max Duty Cycle 0.3% at 100 volts, 5.0% at 5 volts
Max pulse width xxxx at 100 volts, xxx at 5 volts
Max Duty Cycle 0.3% at 100 volts, 5.0% at 5 volts
Min Pulse Width 8ns
Automatic pulse width limiting prevents transformer saturation |
| JITTER |
< 8 ps RMS |
| CONNECTORS |
Signals, SMB; optional SMA
Power, 2.5 mm coaxial, center positive
Tip jacks monitors for HV output level
Tip jacks monitors trigger threshold level
|
| INDICATORS |
Power-on LED |
| POWER |
+12 volts, 0. 8 amps max.
Highland model J12 wall-plug supply is recommended.
|
| ENVIRONMENT |
