powering up the carrier


Hello, I am looking for information on how to turn on the carrier/transmitter permanently so I can run some RSE tests for certification.

It is my understanding that the Q24PL (as do other modems) has an AT command that will power up the transmitter at whatever band selected (850/900/1800/1900). Nothing needs to be transmitted and sending large data files to watch the carrier frequency is not sufficient because GPRS communications are done at 1100 us bursts.

Can anyone provide information on how to do this?
