Performance Verification Test
4. Output a Sine signal with 1 MHz frequency and 6 div amplitude (e.g. 50 mV/div
vertical scale, 300 mVpp amplitude Sine signal) via the Fluke 9500B. Adjust the
horizontal time base to display five cycles of the waveforms on the screen.
5. In the Measure menu, click or tap Vertical measurement item to select "AC.RMS".
The AC.RMS measurement result is displayed in the "Result" sidebar at the right
section of the screen. Read the value and record the measurement result as Vrms1.
6. Use the Fluke 9500B to output a Sine signal with the maximum bandwidth of the
oscilloscope and 6 div amplitude. The bandwidth frequency differs for different
oscilloscope models. For details, please refer to
time base to display five cycles of the waveforms on the screen.
7. Check the AC.RMS "Result" sidebar at the right section of the screen. Read and
record the data as Vrms2.
8. Calculate the amplitude loss with the following formula: Amplitude Loss (dB) = 20
x lg (Vrms2/Vrms1).
9. Repeat Step 2-7. Measure Vrms1 and Vrms2, and calculate the amplitude loss of
500 mV/div vertical scale.
10. Turn off CH1. Measure CH2, CH3, and CH4 respectively using the method above
and record the measurement results.
