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.
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.
NOTE
The Frequency Offset and Relative Frequency functions can be used
simultaneously.
NOTE
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.
