Optic transceivers
One transceiver pair for each bus on the product
Each model converts a specific bus or signal to fibre at the equipment under test and back to electrical at the control room.
CHANGEN, founded in Guangzhou in 2012, develops the fibre-optic transceivers, shielded cameras, antenna stands, low-dielectric fixtures and probes that carry signals out of the chamber and hold the test setup exactly as the standard describes. ICX Lab is the authorised distributor.
Every copper cable that leaves the chamber changes the test. CHANGEN transceivers convert bus and analogue signals to light at the equipment under test, so the operator sees the same data outside the chamber with nothing conductive crossing the wall.
Each model converts a specific bus or signal to fibre at the equipment under test and back to electrical at the control room.
RF fibre-optic links carry antenna and probe signals across the chamber without the loss, pickup and ground loops of coax.
9 kHz to 40 GHz in one channel, customisable to 100 GHz. Also available in 9 kHz to 1 GHz, 100 kHz to 1 GHz, 1 GHz to 6 GHz and 1 GHz to 40 GHz versions.
100 kHz to 6 GHz across eight channels for multi-antenna and multi-probe setups.
Cameras and projectors built to work inside the field, so BAT-IMAGE and similar video monitoring can watch dashboards, screens and warning lights during the test.
Visual target simulator system for camera-based driver-assistance products.
For VHBB 9124 and BBA 9106 antennas, with polarisation adjustment.
Patented low-dielectric-constant material for test tables and fixtures where a normal table would distort the measurement.
Support blocks for automotive EMC setups that need a low-dielectric material.
Low-reflection test table for laboratories that lack one.
