  • *Pulse Characterization Sensors

    mks Ophir

    Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω

  • Zero Bias Schottky Detectors

    Fairview Microwave Inc.

    Fairview Microwave’s line of coaxial packaged zero bias Schottky detectors feature matched inputs for excellent VSWR, voltage sensitivity levels that range from 100 to 500 mV/mW for small signal detection, negative video output polarity, and can withstand maximum input power levels up to +20 dBm CW. Operating temperature range covers 0°C to +90°C and storage temperature of -65°C to +125°C. These zero bias Schottky detectors utilize compact cylindrical package outlines that are made of passivated stainless steel and offer a variety of popular input/output SMA and BNC connector configurations that make them ideal for use with precision test and measurement, instrumentation, and subsystems assemblies. Numerous applications include power measurement, leveling pulsed signal sources, AM noise measurements, radar or missile guidance systems, monitoring system level performance, and pulsed RF measurements.

  • PXI-2720, 8-Bit, 10-Channel PXI Programmable Resistor Module

  • Magneto-Electric Rotation Detector

    MP-981/AP-981 - Ono Sokki

    The MP-981 is a magneto-type detector using a hall element which is suitable for revolution (r/min) measurement from low speed to high speed.Magneto-type detectors use an internal hall element, a permanent magnet, DC amplifier, and voltage regulator and respond to flux, so that a rectangular wave form is derivable from much lower speed all the way though high speed.In addition, a signal indicator is provided in spite of the detector's compact design, making verification of operation and mounting position possible.Meanwhile, the AP-981 is the water and acid proof type, which conforms to Class ' of JIS C0920.
