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.
