3. Record the reference level:
H Disconnect the sine wave generator from the digitizing oscilloscope.
H Connect the sinewave generator to the power sensor.
H Note the level meter reading.
4. Set the generator to the new frequency and r eference level:
H Change the sine wave generator to the desired new frequency .
H Input the correction factor for 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.
H Disconnect the sine wave generator from the power sensor.
