The Teseq-Chase X-Wing BiLog for RF EMC immunity testing The combination of BiLog® technology with novel low  frequency, folded elements (X-Wings®) allows low frequency power to be efficiently projected forward without
significantly affecting the high frequency elements.

The CBL 6140A gives an incredible antenna factor of only 3dB at 26MHz together with a useable VSWR  making the CBL 6140A the first wide band EMC antenna able to deliver 10V/m with 80% AM modulation using an amplifier power of less than 500W# at 26MHz. High Power Handling The CBL 6140A has been optimised for immunity testing to IEC 61000-4-3, and uses a high impedance balun, giving a considerably improved VSWR at low frequencies. Although it is larger in size than the classic emission BiLog®, it is still smaller than any conventional alternative.

The CBL 6140A can handle powers up to 600 Watts and is suitable for testing in most shielded rooms and anechoic chambers. The CBL 6140A covers the requirements for testing medical  equipment to EN 60601-1-2 and FDA (in the US) for RF immunity.

Axial Rotation
The CBL 6140A is supplied with a mount to fit most standard fixings, set at its mechanical balance point. An optional rotating mount, CHA 9440, can be supplied separately for mounting to box section tower booms.
Although primarily designed as an immunity antenna, the CBL 6140A can be used for emission testing and is supplied with individual calibration data. Although primarily designed for use at 26MHz - 2GHz the CBL 6140A
remains useable down to 20MHz.
