AFG31000 Series Arbitrary Function Generator Specification and Performance Verification Technical Reference 47
AC flatness test: >100 kHz
For this test, use a power meter with a power head.
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 >100 kHz:
1. Connect the AFG31000 Series to the power meter with a power head as shown in the following
figure.
Figure 12: Connections for the AC flatness test: >100 kHz test setup
2. Set up the AFG31000 Series as shown in the following table.
Select menu Setting Operation
Function Sine Sine key (front panel)
Frequency 500 kHz Frequency/Period key (front panel)
Amplitude Units dBm Ch1 (or Ch2) menu > Ampl > Units > dBm (touch screen)
Amplitude 4.0 dBm Amplitude/High key (front panel)
Ch1 (or Ch2)
Output
On On key (front panel)
3. Set the frequency of the power meter to match the frequency setting of the AFG31000 Series.
4.
Verify that the power measurement is within the limits specified in the following tables (relative to
the 1 kHz reference power level).
5. Repeat steps 3 and 4 with the AFG31000 Series set to each of the other frequencies specifi ed in
the following tables.
6. (Two-channel models only) Repeat steps 2 through 5 for channel 2 output.
