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

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

2. Slave offset

Type

floating point

 

 

Units

dBm only

 

 

Limits (GSM900)

-100.0 thru +100.0

 

 

Default

0.0

 

 

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.

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

3. Master channel

Type

integer

 

 

Units

none (ARFCN)
