CAT-5 Video Receivers
Analog Devices high speed, differential CAT-5 video receivers and equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths. Our video receivers provide excellent common-mode rejection that enables the use of low cost, unshielded twisted pair cables in noisy environments.

Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm
OSA201C
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

Vibration Unit Tester
BK2020B
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.

300mA One-Channel Amplifiers
Piezo amplifiers/controllers are designed for high precision positioning of low-voltage piezo actuators. These amplifiers are tuned for extremely high output stability and extremely low signal noise at the output. A low amplifier signal-to-noise ratio is very important because it determines the total resolution of the actuator. The nearly unlimited resolution of piezo-electric actuators using these amplifiers results in ultra-precise movement.

Electromagnetic anechoic box/Shield box/Anechoic chamber
The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.
