The Freq Offset annunciator is activated, and the value of the display is

adjusted to reflect the value and sign of the offset entered in Steps 2 and 3.

Since the offset function can be used to add or subtract a fixed value

to/from the measurement result, you can use this feature to tune or align

the odd frequencies of a local oscillator (LO). If you enter the target

frequency as a negative offset, the Counter displays the difference

between the LO’s frequency and the target frequency. You can then adjust

the LO until the Counter displays a value of zero.

NOTE The maximum value that can be entered for Frequency Offset is

± 49,999,999,999 Hz.
