Optimizing Performance
Using an Output Offset, Reference, or Multiplier
Setting a Frequency Multiplier
Using a frequency multiplier, the signal generator can display a frequency that is the multiple
(positive or negative) of the output value.
Displayed Value = multiplier value × output frequency
Output Frequency = displayed value ÷ multiplier value
To set a frequency multiplier:
1. Press Frequency > Freq Multiplier > multiplier value > x.
2. Set the desired frequency.
The display equals the output frequency times the multiplier value.
Examples
When using the signal generator as the input to a system, you can set the frequency multiplier so
that the signal generator displays the output of the system, as illustrated below using a doubler:
