Amplitude test
This test verifies the amplitude accuracy of the AFG31000 Series by checking specific amplitude
points. All output amplitudes are derived from a combination of attenuators and a 3 dB variable gain.
This test uses a 50 Ω terminator. Because the accuracy of the terminator is used as a calibration
factor, you must know the accuracy of the 50 Ω terminator before running the amplitude test.
NOTE. Record the results of this test in the test record for your model in Test records (on page 51
).
To verify amplitude accuracy:
1. Connect the 50 Ω terminator to the DMM (as shown in the following figure) and measure the
register value.
