Direct Reading Attenuator
DAXE
DAXE Millimeter-Wave Direct Reading Attenuator is a measurement instrument for signal level setting or loss measurements in waveguide networks. It also can be used for calibration of other attenuation measurement instruments. Direct Reading Attenuators have rotary-vane design. The value of attenuation is determined by rotation angle of resistive film with respect to the waveguide channel. Attenuation value does not depend on of frequency.The Attenuators are provided in waveguide bands between 18 GHz and 225 GHz.

POWER ATTENUATORS
TYPE ATF
National RF’s Type ATF Power Attenuators were designed to allow interfacing of linear power amplifiers to RF exciters, where a specific amount of drive to the amplifier is prescribed. Often, however, drive from the RF exciter exceeds this minimum prescribed level and some form of power attenuation must be used in order to not damage the input of the power amplifier. National RF’s type ATF-3 offers 3 dB of power attenuation (1/2 of the power) when used between the exciter and the amplifier and will handle an input power of 132 Watts, RMS (continuous power) while providing about 66 Watts RMS output power, when it is terminated into 50 ohms. In practice, the ATF-3 attenuator will handle exciters achieving Peak Envelope Power levels (PEP) in the area of 200 to 250 Watts while providing half of that power to the load. For less attenuation requirements, the ATF-1 and ATF-2 offer 1 and 2 dB of attenuation, respectively.

Motor Test for Stepping Motors
*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.
