7. Rotate HORIZONTAL
SCALE to set the horizontal time base to 1 ns (the setting value is
different for different model of oscilloscope under test; please refer to
Table 2-2).
8. Press MENU  Vrms-N at the left side of the screen of the oscilloscope to turn on the effective
value measurement function. Read and record Vrms2.
9. Calculate the amplitude loss: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1).
10. Keep the other settings of the oscilloscope in step 3 unchanged and set the vertical scale to 200
mV/div.
11. Output a Sine with 1 MHz frequency and 1.2 Vpp amplitude via Fluke 9500B.
12. Repeat step 5.
13. Output a Sine with 500 MHz frequency (the setting value is different for different model of
oscilloscope under test; please refer to Table 2-2) and 1.2 Vpp amplitude via Fluke 9500B.
14. Repeat steps 7 to 9.
15. Keep the other settings of the oscilloscope in step 3 unchanged and set the vertical scale to 500
mV/div.
16. Output a Sine with 1 MHz frequency and 3 Vpp amplitude via Fluke 9500B.
17. Repeat step 5.
18. Output a Sine with 500 MHz frequency (the setting value is different for different model of
oscilloscope under test; please refer to Table 2-2) and 3 Vpp amplitude via Fluke 9500B.
19. Repeat steps 7 to 9.
20. Turn off CH1. Test CH2, CH3 and CH4 using the method above respectively and record the test
results.
