Bluetooth tester runs the lot in 10 seconds
Anritsu has introduced the MT8850A tester to offer manufacturers of Bluetooth modules comprehensive, one-button testing traceable to national standards.
The Optics Group at Bristol is working in three areas: novel components/new materials, RF over fibre, and switching and routing.
In the first of these areas, novel 1.3-1.55um wavelength materials and novel device designs are being investigated for enhanced switching speeds, temperature insensitivity and broadband gain for wavelength division multiplexed (WDM) applications.
Work is also being carried out on short-wavelength (blue) devices based on gallium nitride.

Anritsu has launched the ML8720B, a portable W-CDMA tester for the evaluation of radio propagation characteristics in the area surrounding 3G mobile basestations.
The group fabricates and tests lasers by post-processing using a focused ion-beam etching system.
In the second research area, the group is investigating new subcarrier modulation techniques - an area in which the Anritsu BERT system is being used extensively.
The test system is being used as a parallel data source, allowing the investigation of wavelength division multiplexed systems using the system's four channels.
In the group's third activity, it is researching a fast optical switch matrix for optical packet switching, a fast tuneable laser for optical packet routing and novel integrated all-optical wavelength conversion technology.
Anritsu's ME7750A generates and analyses high-speed pseudorandom digital signals to test components, devices, interfaces and complete transmission equipments.
It includes a four-channel pattern generator, a four-channel error detector, and multiplexer and demultiplexer units, and provides all the necessary tools to thoroughly analyse any bitrate, with operation frequency from 100MHz to 43.5GHz.
Showing excellent specifications for waveform shape and sensitivity, the system can be used to test a 40Gbit/s signal with forward error correction (FEC) redundancy up to 43.5GHz, or four parallel channels at 10Gbit/s with FEC.
"We are really excited by the prospect of the new research possibilities that the 43G BERT opens up: both continuing our existing research activities and pursuing new avenues with new partners", said Dr Judy Rorison, Head of the Optics Group at Bristol University's Electrical and Electronic Engineering Department.
"We are also looking forward to offering a service to companies either utilising time on the system or contracting us to examine their components.
We believe that this will lead to fruitful new research.
The Bristol Optics Group is very grateful to Anritsu for its donations".
"Anritsu's Philanthropy Programme is aimed at 5* and above, or Universities whose research aligns itself with Anritsu's strategic plans", said Ken Foan, Anritsu's UK Sales Manager.
We have already identified several that meet our criteria and have made grants to enable them to purchase equipment that they would otherwise not be able to afford.
The universities can also obtain Government funding to match the donations they receive from Anritsu.
The programme is also working with universities in other ways, including sponsoring awards for best student, best academic paper and others".
