Offset Soft Key
The Offset key allows the operator to adjust the Instrument output via an offset from the
main setting. The soft label tracks the focus field, allowing control of either Frequency
Offset or Level Offset.
For example, assuming Level to be the current focus field, pressing the Offset soft key
will add and select the Level Offset field as the new focus field. In the following Leveled
Sine screen, a new indicator appears on the Status Bar indicating that Offset is on.
This new Offset field supports Cursor or Numeric edit and its value will be added to the
current output to give a new output level. See the following Leveled Sine – Offset
Applied screen. The display indicates the current output level and the offset value that
achieves it.
Note that editing the main Level field with Level Offset enabled causes the current
Offset value to reset to zero. In addition, pressing the Offset Disable soft key clears the
Level Offset field and its related status bar indicator and soft labels.
