Figure 1–41: Sine wave generator leveling equipment setup
1. Install the test hookup: Connect the equipment as shown in Figure 1–41.
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 digitizing 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 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.
