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.
