Offsetting a Frequency Measurement

You can use the Frequency Offset (Freq Offset) function to add or subtract
a constant value to/from a frequency measurement. For example, you can
use an offset to compensate for a systematic error or to display the
difference in frequency between two signals.
The Frequency Offset and Relative Frequency functions can be used
simultaneously.
To display an offset frequency measurement, you need to set the value and
sign (+/–) of the offset and to turn the Frequency Offset function on. In the
diagram on the next page, the Frequency Offset function is enabled first,
and the offset value is then entered. However, the order doesn't matter,
so you can also enter the offset value first, and then turn the offset
function on.
When you are entering a value for Frequency Offset (or Power Offset),
you can use the Reset key to restore all of the displayed digits to zero.
These are the only two functions in which the Reset key has this effect.
