Research in mmWave communication applications.

We at Vigven are actively pursuing research in the millimeter wave area to deliver products to our customers using the existing commercially available test equipment (COTS)

Exploration in the mmWave frequencies has taken giant leaps in the past few decades with the advancement in devices physics and fabrication of mmWave components. In particular, the 71–76, 81–86 and 92–95 GHz bands are also used for point-to-point high-bandwidth communication links, inter-satellite links, and point-to-multipoint communications. There are tentative plans to use millimeter waves in the future for 5G mobile phones

These higher frequencies do not suffer from oxygen absorption. There are plans for 10 Gbit/s links using these frequencies as well. In the case of the 92–95 GHz band a small band has been reserved for space-borne radios, limiting this reserved range to a transmission rate of under a few gigabits per second.

The smaller wavelengths in the band permit the use of smaller antennas to achieve the same high directivity and high gain as larger ones in lower bands. Due to the high directivity, coupled with the high free space loss at these frequencies, there is   great scope for a more efficient use of frequencies for point-to-multipoint applications. A large number of highly directive antennas can be placed in a given area, which will enable frequency reuse and also increase the number of users. The large usable channel capacity in this band also will allow for some applications and could be a replacement for the optical fiber.

    Application Note – Mechanical Measurements Using Digitizers

Application Note – Mechanical Measurements Using Digitizers

Measurements on mechanical devices and systems using a modular digitizer requires the use of a variety of transducers or sensors in order to convert mechanical parameters such as force, acceleration, pressure, rotational speed, and their kindred into electrical signals you can measure. This article is a primer on making such measurements using a modular digitizer.

    Pre-amplifiers extend digitizers dynamic range and sensitivity

Pre-amplifiers extend digitizers dynamic range and sensitivity

For applications where low level electronic signals need to be acquired and analyzed Spectrum has added a range of pre-amplifiers that can be used to boost signal levels. When combined with a Spectrum digitizer these low noise pre-amplifiers can greatly increase the measurement systems overall dynamic range and sensitivity. The new pre-amplifiers are designed to compliment the built-in amplifiers of the digitizer, effectively extending the available input ranges, and allowing the detection and measurement of much smaller signals.

Spectrum publishes a free Digitizer Handbook

To  keep engineers and scientists up to date with the latest developments in PC based digitizer technology Spectrum has published a handbook that covers the major product features of this powerful class of instrument and also explains when a digitizer can replace an oscilloscope. The 120 page booklet is printed in full color and includes a number of graphical images that highlight and explain key digitizer concepts and their application.

Topics covered include how and when to select a digitizer, understanding the various terms and comparing their performance with other instruments, such as digital oscilloscopes. The handbook then has sections that explain how to achieve the best performance from a product with emphasis being given to measurement speed and accuracy. Examples show how to setup a digitizer and use the various acquisition, trigger and readout modes to ensure important events are always captured and that the acquired data is analyzed as fast as possible. More examples demonstrate the effects of proper signal conditioning and explain how digitizers can be used with a variety of different probes and sensors.

The handbook then discusses the importance of software and what effect this has on project development. It explains the structure of device drivers and how you can program the cards using today’s most popular programming languages such as Visual C++, Borland C++, Gnu C++, Visual Basic, VB.NET, C#, J#, Python and Delphi as well as with third party software tools such as LabVIEW and MATLAB. To help with programming the handbook discusses the advantages of using debug logging and other tools that allow you to test hardware setups and assess their potential data transfer speeds. For those not wanting to develop their own code there is even a […]
