J736 single-channel compact high-voltage optical-to-electrical converter

The J736 is a 2" x 3" high-voltage optical-to-electrical converter. DC-coupled, it converts fiberoptic input to an adjustable-voltage digital output. The J736 features the T577 GaN output driver, capable of driving PIN diodes, optical modulators, bar lasers, and SiC mosfet gates. It is an excellent alternative to long lossy coaxial cable runs when distributing fast pulse, logic, and trigger signals over long distances in large systems.

T130 single-channel picosecond EOM driver

T130 is a USB/RS-232 enabled pulse generator suitable for driving LiNbO3 Mach-Zehnder and similar electro-optical devices. Unlike typical telecom class EOM driver modules specified for balanced data operation, the T130 output can swing up to 7 volts relative to baseline and is capable of driving high Vpi EOMs at low duties down to single-shot. It includes a bias tee injection inductor for operation with single-port modulators. An integral adjustable -6 volts to +6 volts low-noise DC bias generator is included. A routing relay and dedicated SMA bias jack enable externally applied bias to be applied to the RF pulse. The BIAS SMA connector functions as a hi-z monitor of bias voltage when set to internal generator mode. The T130 is housed in a compact and rugged extruded aluminum enclosure, ideal for benchtop or OEM applications. An aluminum baseplate is included for surface mounting.

P900 3-phase power source and permanent-magnet alternator simulator

The P900 is a 3-phase programmable sine wave power source and permanent magnet alternator simulator. Each transformer isolated phase output provides adjustable power up to 200VA, useful for simulating aircraft FADEC power busses and PMA permanent-magnet alternators. Output voltage can be set from 0 to 160 VRMS with 4 available ranges, at frequencies from 120 Hz to 4 kHz, including applications requiring a 400 Hz AC power supply source. Output impedance can be programmed to simulate low-impedance voltages sources, or alternators with source impedances up to 160-Ohms. Each phase can be programmed to drop out for a selectable amount of time, simulating an open winding alternator fault. The front panel includes status LEDs and BNC connectors for monitoring RMS current and voltage of each phase with an oscilloscope. A full built in self-test BIST routine regularly checks that critical internal circuit voltages are nominal. Outputs are robust, with over-current protection, voltage limiting and MOV transient suppression to limit inductive transients typical of shunt MOSFET regulators. Full USB, TCP/IP and UDP serial support is standard, facilitating remote management and integration with large systems. The P900 is housed in a 19", 3U aluminum rackmount enclosure and operates on 90 thru 264 VAC, 47-63 Hz wall power.

J270 adjustable delay and width electrical pulse generator

The Highland J270 is a very compact GaN-based nanosecond high-voltage pulse generator with adjustable analog control of time delay and pulse width. The standard version can make 0.8 to 20 volt fast-and-flat pulses. A version that can output 44 volt pulses is also available, as well as OEM and higher voltage versions for use as embedded bar laser, optical modulator, intensifier gate, PIN diode, or cable drivers.

P348 dual-channel benchtop I/Q modulator

The P348 is a two channel quadrature modulator. Each channel's isolated sine wave input is split into quadrature (90 degree real/imaginary) phases and precision multiplied by user-supplied DC-coupled bipolar baseband input signals, then summed into an isolated output. It can simulate a wide range of inductive proximity and eddy-current transducers, such as jet engine blade tip sensors, automotive engine measurements, and sub-micron semiconductor fabrication equipment sensors. It is also suitable for precision RF modulation, SSB generation, and mixing operations.

T124 1 to 4 logic buffer

The T124 logic buffer provides a fast 1 to 4 fanout buffer/inverter for digital logic signals. Input features a switchable 50R or high-impedance termination, as well as a switchable 10MHz bandpass filter for use as a clock distribution amplifier. Outputs can be switched between a low-impedance or 50R source, and the output high voltage is switchable between 3.3V and 5V. The short-circuit protected outputs can be used for any digital logic distribution application.

T850 Pockels Cell Driver

The T850 Pockels Cell Driver is a fraction of the size, power consumption, and price of conventional devices. Its small size and very low power requirements allow it to be mounted immediately adjacent to the Pockels Cell in an optical system. There are no fans or other sources of vibration. Similar to the T850, complementary standard and custom timing controllers that manage pulse picking, Q-switching, chirped pulse amplification, cavity dumping, and two-photon microscopy can be developed for custom/OEM applications.
