IC is the abbreviation of Industry Canada , is an acronym for Industry Canada , IC provides testing standards analog and digital terminal equipment and the provision of wireless products sold in Canada must pass the certification of the IC. So IC certification is wireless electronic products entering the Canadian market permits and prerequisites .

    According to the standard RSS-GEN and standard ICES***3e IC developed by the relevant requirements of wireless products ( eg mobile phones ) must comply with the relevant EMC and RF limits and comply with RSS***2 of the SAR requirements. In GSM**0/***0 GPRS function modules contain or phone, for example , EMC tests have RE radiation harassment , CE conduction disturbance tests. In the SAR evaluation , the actual use of the *0cm distance wireless module above , in accordance with the relevant provisions similar MPE FCC defined way to assess radiation safety. Here we talk to GSM**0/***0Mhz GSM phone, for example in the RF IC certification program .

The formula for the frequency stability of K units of ppm (part per million parts per million ) . It is an important indicator of good or bad quality of the communication device .

    Test Method : As common base Agilent ***0 and R & S has a frequency stability test function , and therefore the test , simply EUT and the base station directly connected together , you can use the base station testing .

    Test conditions : Test frequency stability should be at **0 ° to **0 ° ambient temperature as are :

? The normal voltage state, the environment of **0 ° C for half an hour to place the measured value , the test value then is placed after a half hour at **0 ° C environment , the same interval of *0 ° C rise in temperature until *0 ° C , the test values ​​;

? State at high voltage and low voltage state , the test procedure and the normal operating voltage state on the same principle ;
