The Master Input level ﬁeld sets the expected power of the master uplink TCH. You can set the level indirectly by changing the master Tx level (see page 33) or you can change it directly. This value is used to set the RF analyzer level when the measurement timeslot (see page 32) is set to Master.

If the instrument is operating in standard mode, setting this ﬁeld changes the master control type (see page 35) to Manual.

If the instrument is operating in compatibility mode and the master control type is MS TX Lev, then the instrument returns the error Can’t change setting while MS TX Lev mode is selected and does not make the setting.

When the measurement timeslot is set to Master, this ﬁeld always has the same value as the RF I/O analyser level.

NOTE	The default is reset when you select the instrument type (see page 24).
