2. Set the Generator:
H Set the sine wave generator to a reference frequency of 10 MHz.
H Adjust the sine wave generator amplitude to the required number of
divisions as measured by the oscilloscope.
3. Record the reference level:
H Disconnect the sine wave generator from the oscilloscope.
H Connect the sine wave 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 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 for your specific test procedure.
H Disconnect the sine wave generator from the power sensor.
Connect the sine wave generator to the oscilloscope and proceed with the test
instructions that require a leveled sine wave generator at the frequency you set in
step 4.
