adding an offset (see page 28) to this value.

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

2. Slave offset

The Slave offset ﬁeld determines the downlink amplitude of the

master TCH by selecting the difference in amplitude between the master

and slave amplitudes. Below this ﬁeld there is a read-only reminder of

the absolute level of the slave TCH.

Note that the resultant absolute amplitude must lie within the normal

RF generator limits (-127.0 thru +1.0 dBm). The error Disallowed due

to pulse mod configuration is returned if these limits are exceeded.

On a master unit, changing the Slave offset ﬁeld has no effect other

than copying the value to the slave unit when being operated manually.

On a slave unit, changing the Slave offset ﬁeld changes the downlink

amplitude of the unit. This ﬁeld, when added to the master downlink

amplitude (see page 27) always has the same value as the RF I/O

generator amplitude.

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