Setting an Output Offset

Using an output offset, the signal generator can output a frequency or amplitude that is offset
(positive or negative) from the entered value.
RF Output = entered value − offset value
Displayed Value = output frequency + offset value
To set an offset:
• Frequency: Press Freq > Freq Offset > offset value > frequency unit.
• Amplitude: Press Amptd > More > Amptd Offset > offset value > dB.
Examples
Parameter
Entered (and displayed) Value:
Offset:
Output Frequency:
When using the signal generator as a local oscillator (LO), you can use the offset to display the
frequency of interest, as illustrated below:
122
Indicates that an offset is on
Example Example Example
#1 #2 #3
300 MHz 300 MHz 2 GHz
−50 MHz −1 GHz
50 MHz
250 MHz 350 MHz 3 GHz
Comments
The entered value must be positive.
An offset value can be positive or negative.
The signal generator alerts you if the
output frequency or amplitude is out of range.
