CALL:MODulation

Last updated: December 3, 2008

CALL:MODulation[:FORMat]:CONTrol:AUTO

Function	GSM TA	This command is not applicable to GSM.
	GPRS TA	This command is not applicable to GPRS.
	GSM/GPRS LA	This command is not applicable to the GSM/GPRS LA.
	EGPRS TA	This command sets/queries the modulation format control state. If set to On, the test set determines which modulation type to expect based on a combination of the current Cell Operating Mode, the current System Type, and the current Modulation Coding Scheme on the uplink. Coding Schemes MCS1 through 4 use GMSK modulation; MCS5 through 9 use 8PSK modulation. If set to Off, the modulation format control is set to manual, allowing you to set each burst individually to expect either GMSK modulation or 8PSK modulation.

Requirements	GSM/GPRS/ EGPRS TA	Revision: A.03 and above

CALL:MODulation[:FORMat]:MANual:BURSt[1]|2|3|4|5|6|7

Function	GSM TA	This command is not applicable to GSM.
	GPRS TA	This command is not applicable to GPRS.
	GSM/GPRS LA	This command is not applicable to the GSM/GPRS LA.
	EGPRS TA	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 the modulation format is set to GMSK, but an 8PSK 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 . Bursts 5 through 8 only apply when the operating mode is set to `FastTune` .
