Is there a transmitter diagnosis mode?

Is there a configuration that can produce a continuous transmission?
at 100% duty cycle, feeding as fast I can at 57600, it seems it is still sending far from continuously.
Even with only 1 frequency.
Can SiK be somehow tested to transmit continuously on a single frequency? (in order to test actual output using a RF power meter?)

The one possible method is to restrict frequency and channel number by AT commands. Then you should use a spectrum analyzer to measure the radiated energy in the spectrum.
I do not know how it could be managed with a simple RF power meter. The use of a spectrum analyzer is probably the safest option because it also allows checking spurious out-of-band RF leakage.
