Beam Directing and Reflecting Optics
Beam directing and reflecting optics simply reflect, bend or translate the beam, but do not typically modify the polarization, except for polarizing beam splitters. For example, mirrors, cube corners and retroreflectors are attached to objects that move in order to keep the weight down on the moving object (instead of mounting the interferometer on the moving object).

4000B ARINC-style Directional Gyroscopes
This instrument was developed for those pilots that prefer the distinct, professional look of an ARINC-styled cockpit. It is identical to the standard 4000B model differing mainly in aesthetics. Besides its distinct bezel and airplane, the display graphics and colors differentiate it from the standard model. A heading reminder bug is available as an option.

Standard Directional Gyroscopes
4000B-series
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

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.

Direct 3D RightMark
D3D RM
D3DRightMark is an independent non-commercial open-source graphics card benchmarking project developed by iXBT.com. It's called to help users estimate graphics cards performance and quality in synthetic tests and real apps, e.g. games. Synthetic tests allow estimating performance and capabilities of separate graphics cards subsystems in order to forecast their behavior in either applications, both existing (that is overall estimation of suitability and prospects for an entire application range) and developing, provided that a given accelerator demonstrates peculiar behavior under such applications.

RED Directive Testing & Certification
The Radio and Telecommunications Terminal Equipment Directive (R&TTE Directive 1999/5/EC) has been in place in the EU for many years serving radio and telecoms technology. To accommodate developments in radio equipment technology and to align with the requirements of the New Legislative Framework (NLF), the EU R&TTE Directive has been re-written. As of 2016, the European Commission replaced the R&TTE Directive with the Radio Equipment Directive (RED), which establishes safety and electromagnetic compatibility (EMC) requirements for equipment using the radio spectrum. Following June 13, 2017, after a one year transition, the RED 2014/35/EU replaced the R&TTE Directive. All new and existing products within the scope of the RED must comply in order to achieve CE marking.
