*Stable measurement: Since it uses Prony braking, this model provides stable measurement unaffected by moments of inertia and no coupling loss. In addition, the resulting measurements allow data correlation via the traditional double-balance method.*Precision measurement method: This model’s judgment of synchronization loss achieves high stability using algorithms developed by Sugawara Laboratories. Measurement mode can be chosen based on step angle. For pull-in torque, startup can be measured consistently from the holding state. Allows measurement at 1-Hz resolution.*Broad measurement range: This model offers a range of seven available measurement heads, from 0.5 N to 50 N, allowing use for high-precision measurements. Through selection and use of pulleys, this model can also be used to measure small motors of 0.5 mN·m or less or 500 mN·m motors. Pulley diameters and other settings are easily configured using a personal computer running Windows®. Note: Any of the seven available heads may be attached to a single measurement component.*High-visibility measurement data: Motor characteristics are easily ascertained on automatically plotted performance graphs. Measurement data can be overlaid up to four times. In addition, the cursor can be used to read accurate values from measurement points. Hard copies of data displayed on-screen can be printed from a personal computer.*Can be controlled using standard personal computers: Allows control of measurement operations and display and storage of data from a standard personal computer running Windows®. Data is stored in CSV-format files for compatibility with other software applications.

Millimeter Wave Continuously Variable Waveguide Attenuators
-
Our millimeter wave variable waveguide attenuators allow designers and engineers to test their systems at various signal strengths and attenuation values to determine the optimum signal performance of the system. The key feature of these waveguide attenuators is that the attenuation level is adjusted using a built-in micrometer which enables repeatable and rapid re-setting to different attenuation levels without the need for additional external components. Our waveguide attenuators handle varying attenuation levels from 0 to 30 dB over the specified band allowing the designer to tune the attenuation level needed for the application. These continuously variable waveguide attenuators cover a broad frequency range of 33 to 110 GHz in five bands and also display flat performance across a wide band with low insertion loss.
