Tality helps Advantest to Bluetooth solution
Tality Corp, a subsidiary of Cadence Design Systems, is collaborating in the development of Advantest's Bluetooth Protocol Tester.
The EMC facility is UKAS accredited and provides a comprehensive test, design advice, prediction and analysis and computational electromagnetics service to cover a wide range of specifications.
Very large systems or individual units can be accommodated in test chambers up to 1800m3 volume.
Capabilities include lightning/NEMP/ESD assessments, classical qualification EMC testing, transient/rad haz safety trials and design advice and prequalification testing.
The new EMC anechoic chamber is 11.5 x 6.5 x 5.2m with internal dimensions of 10.5 x 5.5m.
The walls are lined with TDK hybrid absorber utilising ferrite panels and styrofoam wedge absorbers, which attenuates fields from 30MHz to 40GHz.
The new EMC/sensors chamber is 11.5 x 5 x 5m with internal dimensions of 9.6 x 3.1m.
The walls are lined with AEMI pyramid absorber, attenuating fields from 30MHz to 100GHz.
Both rooms are fully 59-41 and 461E compliant and is equipped with removable penetration panels.
Access for test pieces is via 3 x 3m double doors, so both rooms are capable of accommodating both large and small systems and components.
Fully equipped 4 x 3m support rooms are located next to each chamber.
The facility also includes a reverberation, or mode stirred, chamber which is 8.4 x 4.2 x 5m and is constructed from a galvanised steel sandwich with a steel sheet floor.
It is equipped with a paddle stirrer (2m diameter x 1m deep) made from aluminium sheet.
This has the following characteristics: frequency range 200MHz to 40GHz; minimum pulsewidth 20us (typically 30us); minimum stirring ratio 20dB; and field strength up to 4500V/m.
A new support room has been panelled into the main chamber.
