Modem Factory test mode for EC25-EUX

Trying to test our EC25-EUX modem in QMI mode for EMC approval.
I have found a Factory test mode instruction document that talks about AT+QRFTEST for continuous transmit.
This command seems ideal to test in an EMC chamber, how do I enter FTM to use this command - is it
AT+QRFTESTMODE=1

yes,yes,yes,AT+QRFTESTMODE=1

Excellent, I have tested and it accepts the messages and returns “ALL IS UP” - Is this correct operation?
I need to know before I book time in an EMC lab to test.
