4-26 AFG3000 Series Arbitrary/Function Generators Service Manual
AC Flatness Test
This test verifies the flatness of a sine wave to 100 kHz sine wave.
1. Connect the arbitrary/function generator to the power meter with a power head
as shown in Figure 4-6.
Figure 4-6: AC flatness tests
2. Set up the arbitrary/function generator using the following steps:
3. Set the frequency of the Power Meter to 100 kHz.
4. Write the Power Meter reading of the 100 kHz sine wave as a reference power
value.
5. Verify that the power measurement at each frequency is within the error
specified in the following tables.
