Chapter 2 Operating Your Frequency Counter

Offsetting a Frequency Measurement

6Press the Offset On/Off key.

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.

The display should look like this:

GHz

MHz

kHz

Hz

Offset

 

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.
