AC flatness test
This test verifies the flatness of a sine wave. There are two different test setups for this test:
 1 kHz reference waveform test setup; uses a high-performance digital multimeter (DMM)
 >100 kHz waveform test setup; uses a power meter with a power head
AC flatness test: 1 kHz
For this test, use a high-performance (5.5-digit or higher) digital multimeter (DMM) with a 50 Ω
terminator.
NOTE. Record the results of this test in the test record for your model in Test records (on page 51
).
To verify AC flatness at 1 kHz:
1. Connect the 50 Ω terminator to the DMM (as shown in the following figure) and measure the
register value.
Figure 10: Connections for the 50 ohm terminator measurement
2. Calculate the 50 Ω calibration factor (CF) from the reading value and record as shown in the
following table.
50 Ω calibration factor (Calibration factor (CF) = 2 / (1 + 50 Ω /
Measurement Ω) =)

Examples
50.50 Ω
1.0050 (= 2 / (1 + 50 / 50.50))
49.62 Ω
0.9962 (= 2 / (1 + 50 / 49.62))
