  • SOA Driver

    S-109 - Notice

    SOA Driver slot module of FOTS system offers a special function that changes the amplification feature of input optical signal variously, by dynamically driving a built-in SOA module. This SOA Driver is an efficient module that can drive a high gain and low noise amplifier stably and modulate a high power amplified signal up to the rate of 155 Mbps. As a high power amplifier, this module drives the maximum amplified power of more than 10 dBm and has a stable broadband source characteristics of > 0 dBm. As a high-speed modulator of amplified signal combined with high current (400 mA) modulation technique, it outputs a high power and high bit rate amplified signal of > 155 Mbps with > 10 dBm peak power.

  • Multi-Stage Injection Measurement System

    Ono Sokki

    Common rail fuel injection system in diesel engines is a fuel injection system which improves output performance and fuel consumption by purifying exhaust gas (soot, NOX) and reducing noise and vibration.The fuel is completely burned by being sprayed in the form of mist which burns easily at high pressure, and furthermore the combustion timing is optimized with electronic control.In this common rail injection system, injection timing by an electric controlling has great effect on the performance of an engine. So measurement of injection amount, injection rate, and injection timing are very important. FJ-8000 series Multi-Stage Injection Analyzer is able to measure those parameters for every 1 cycle by simulating in the environment which is near to an actual vehicle running.

Built-in Non-Contact AC Voltage Detector quickly checks for the presence of AC Voltage before testing. Features a 4000 count LCD display, data hold, min-max, relative mode, capacitance zero, auto power off, continuity and diode test. This meter will measure AC/DC voltage to 600 V and AC/DC current to 10 amps. Complete with test leads, manual and two AA batteries.

  • Vibration Unit Tester

    BK2020B - BaKo Co., Ltd

    We developed the BK2020B as an upgrade to our BK2020 to test the electrical specifications (RPM, current, drop pulse, start up voltage) of your cylindrical or coin type vibration units. You can also test vibration level, noise, isolation resistance, and the DC resistance. The DUT power supply and all measurement components are self contained, so external devices aren't needed and the tester uses DSP, making it capable of fast, highly accurate and reliable measurements. The BK2020B is very versatile. It can be set up as a stand alone machine, or used with a PC and software for access to more information, and to save the data for analysis. Either version is great on the product line but you may also use it for QA, QC and development.

  • USB-8452, 3.3 MHz I2C, 50 MHz SPI I2C/SPI Interface Device

    781964-03 - NI

    The NI USB‑8452 is a master interface for connecting to and communicating with inter-integrated circuit (I2C) and serial peripheral interface (SPI) devices. With plug‑and‑play USB connectivity, the USB‑8452 is a bus-powered, portable solution to communicate with consumer electronics and integrated circuits. It also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I2C devices, toggling LEDs, or strobing convert and data ready lines common to analog converter chips. You can physically place the USB‑8452 more closely than PCI interfaces to I2C/SPI devices, which reduces I2C bus length and minimizes noise problems. Additionally, the interface provides +5 V and GND to power circuits with no external power supply.
