This command sets/queries the modulation format manually for the burst you specify in the multislot configuration. If you expect your mobile to transmit a GMSK (Gaussian Minimum Shift Keying) signal, you should set this command to GMSK. EGPRS modulation coding schemes MCS1 through MCS4 use a GMSK modulated signal. If you expect your mobile to transmit an 8PSK (Eight Phase Shift Keying) signal, you should set this command to EPSK. EGPRS modulation coding schemes MCS5 through MCS9 use an 8PSK modulated signal. If you expect your mobile to transmit an 16QAM (Sixteen Quadrature Amplitude Modulation) signal, you should set this command to 16QAM. EGPRS2A modulation coding schemes UAS7 through UAS11 use an 16QAM modulated signal. If the modulation format is set to GMSK, but an 8PSK or 16QAM signal is applied the measurement discards all bursts until it locates a GMSK burst. The measurement does not complete until it locates a burst of the type it expects. You must set the modulation format control state to manual before using this command. See CALL:MODulation[:FORMat]:CONTrol:AUTO .
