  • Multiple Channel Burn In Power Supply

    MCPS - Test Electronics

    The most important features of this burn in power supply is its ability to hold a constant output for each channel even in the event that a unit under test on one channel may short and fail. Since each channel has it''s own transformer, no glitches or voltage spikes can get into any of the other channels. This image shows the results as the second channel from the left is shorted with a small wire and the circuit breaker pops out. Used for burn-in testing and other timed testing where power isolation is required. Very basic simple circuit, see schematic below. Cleans and frees up benchtops, burn in racks and work space clutter. Available in benchtop or rackmount.

  • Furnaces

    Instron

    These three zone resistance wire wound furnaces are of split construction to facilitate fast and easy loading of a pre-assembled specimen train. The case is constructed from stainless steel with aluminium and hardened insulation board end plates. The optional front cut-out allows the use of side-entry high-temperature extensometry. Adjustable stainless steel latches keep the furnace halves locked together during use, but are then easily opened once testing is complete. The furnace is available with optional heavy duty brackets or mountings, which attach to a wide range of testing systems. An extensive range of standard controllers is available to suit most test regimes. Custom variants can be specified should the standard range not include a suitable unit.

  • Anemometers

    Fieldpiece Instruments, Inc

    Anemometer accessory head for use with our modular instruments that measures air velocity and temperature in English or Metric units: Ft/min, M/s, MPH, KM/hr, ºF (degrees Fahrenheit) or ºC (degrees Celsius). Multiply your air velocity by the register’s free area to estimate CFM or diagnose duct blockages and quickly check the airflow balance in a conditioned space. Use with our DL3 Data Logger to track airflow or temperature over time. Features average and real time testing modes.

  • Digital Oscilloscope, 4 Channel, 200 MHz, 2 GSPS, 24 kpts, 1.8 ns

    72-8727 - Tenma

    Tenma 72-8727 DSO four-channel digital storage oscilloscope offers a user-friendly front panel with clear indications to allow access to all basic functions for easy operation. The scaling and position buttons for all channels are optimally arranged for intuitive operation. The design is based on the familiar practices of traditional instruments users can use the new units without spending considerable time in learning and familiarizing with operation. For faster adjustment to ease testing, there is an Auto key to instantly display the appropriate waveform and range position.

  • PDL Emulator

    PDLE-101 - General Photonics Corp.

    The PDLE-101 is specially designed for such PDL-related tests. This PDL source/ emulator can generate individual PDL values between 0 dB and 20 dB, with a resolution of 0.1 dB for PDL tolerance testing. It can also generate variable PDL with user defined range, waveform, and speed for PDL tracking speed and recovery time tests. The instrument can be controlled via the front panel keypad or by remote control via USB, RS-232, GPIB, or Ethernet interfaces. The residual PMD of the unit is less than 0.1 ps.
