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 following
example, 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.
Frequency Offset Example
1 Connect a cable from the 10 MHz reference output on the back panel to the
Channel 1 input connector, and press the Chan Select key (if necessary) to
activate Channel 1.
The display should look like this:
2 Press the Shift key, and then press the Freq Offset (Rate) key.
The Shift annunciator activates when you press the Shift key. When you press
the Freq Offset key, the Shift annunciator disappears, and the Freq Offset
annunciator at the left side of the display activates.
