Due to inability to communicate with the outside signal in an absorber-lined chamber, the telematics product can’t fully simulate as it is installed on vehicle during the EMC test. This technique utilizes the antenna signal coupling, appropriate filtering devices, wireless communication signal generators and analyzers to establish telematics signal connection , and without affecting the electromagnetic compatibility test. Furthermore, the EUT functional status like frequency error, bit error rate, error vector magnitude and other parameters could be recorded in real time.
 

1.Scope of applications: EMC testing for telematics product
2.Test frequency of WCDMA system: Band I to Band XIV
3.Test frequency of CDMA2000 system: Band Class 0 to Band Class 17
4.Modulation analysis of IEEE 802.11p DSRC: Error Vector Magnitude, Frequency Error, Symbol Clock Error, Frequency and etc.
5.Simulated signal of GPS: 8 satellite signal simultaneously with date, time, longitude and latitude of the location
6.Conform to test methods of ISO11452-2, CISPR25 and etc.
