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:
HSet the sine wave generator to a reference frequency of 10 MHz.
HAdjust 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:
HChange the sine wave generator to the desired new frequency.
HInput the correction factor for the new frequency into the level meter.
HAdjust 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.
