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.
