H
Adjust the sine wave generator amplitude to the required number of
divisions as measured by the oscilloscope.
3.
Record the reference level: Note the reading on the level meter.
4. Set the generator to the new frequency and reference level:
H
Change the sine wave generator to the desired new frequency.
H
Input the correction factor and/or the new frequency into the level
meter.
H
Adjust the sine wave generator amplitude until the level meter again
reads the value noted in step
3 . The signal amplitude is now
correctly set for the new frequency.
Equipment
