4-32 AFG3000 Series Arbitrary/Function Generators Service Manual

Spurious Test

This test verifies the spurious using a spectrum analyzer.

1. Connect the arbitrary/function generator to the spectrum analyzer as shown in

Figure 4-9.

Figure 4-9: Spurious tests

2. Set up the arbitrary/function generator using the following steps:

3. Set the center frequency of the spectrum analyzer to 10 MHz. Other settings

are shown in the following tables.

4. Set the Ref Level of the spectrum analyzer to 8 dBm.

5. Measure the maximum spurious level other than harmonic distortion of 1 V

sine wave in each frequency.

6. Set the center frequency of the spectrum analyzer to 300 MHz. Other settings

are shown in the following tables.

7. Measure the maximum spurious level other than harmonic distortion of 1 V

sine wave in each frequency.

8. Verify that the spurious signal at each frequency is equal to or less than the

limit specified in the following tables.
