RF Generator Level Offset
The RF Generator Level Offset parameter accounts for a loss or gain to be inserted into the RF
path between the 3900 generator output connector (GEN (Generator) Connector
or T/R
Connector) and the device under test.
The Offset value is indicated in +dB for positive (gain) values. When a positive value is entered,
Ext Gain is displayed to the right of the RF Generator Level Offset value field.
The Offset value is indicated in -dB for negative (loss) values. When a negative value is entered,
Ext Loss is displayed to the right of the RF Generator Level Offset value field.
When an offset is enabled, the warning symbol is shown beside the output level entry field on
the Generator Tile.
Level Offsets set in the Analog Duplex system are independent of any Level Offsets set in
any other System on the Test Set.
