compare the result with the specification. At this point, the amplitude loss should be within
the specification range.
11) Output a Sine with 200 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
12) Rotate HORIZONTAL
SCALE to set the horizontal time base to 5 ns.
13) 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 Vrms3.
14) Calculate the amplitude loss: Amplitude Loss (dB) = 20 × lg (Vrms3/Vrms1). At this
point, the amplitude loss should be lower than -3 dB.
15) Keep the other settings of the oscilloscope in step 3) unchanged and set the vertical scale to
200 mV/div.
16) Output a Sine with 1 MHz frequency and 1.2 Vpp amplitude via Fluke 9500B.
17) Repeat step 6).
18) Output a Sine with 100 MHz frequency and 1.2 Vpp amplitude via Fluke 9500B.
19) Repeat steps 8) to 10).
20) Output a Sine with 200 MHz frequency and 1.2 Vpp amplitude via Fluke 9500B.
21) Repeat steps 12) to 14).
22) Keep the other settings of the oscilloscope in step 3) unchanged and set the vertical scale to
500 mV/div.
23) Output a Sine with 1 MHz frequency and 3 Vpp amplitude via Fluke 9500B.
24) Repeat step 6).
25) Output a Sine with 100 MHz frequency and 3 Vpp amplitude via Fluke 9500B.
26) Repeat steps 8) to 10).
27) Output a Sine with 200 MHz frequency and 3 Vpp amplitude via Fluke 9500B.
28) Repeat steps 12) to 14).
29) Turn off CH1. Test CH2, CH3 and CH4 respectively using the method above.
3. 200 MHz bandwidth limit test
1) Connect the active signal terminal of Fluke 9500B to CH1 of the oscilloscope, as shown in
Figure 2-4.
2) Turn on Fluke 9500B and set its impedance to 50 Ω.
3) Configure the oscilloscope:
a) Press CH1 in the vertical control area (VERTICAL) at the front panel to turn on CH1.
b) Press CH1  Probe  Ratio to set the probe attenuation ratio to “1X”.
c) Press CH1  Input to set the input impedance of CH1 to 50 Ω.
d) Rotate VERTICAL SCALE to set the vertical scale to 100 mV/div.
e) Rotate HORIZONTAL SCALE to set the horizontal time base to 500 ns.
f) Press HORIZONTAL POSITION and VERTICAL POSITION respectively to
set the horizontal position and vertical position to 0.
g) Press TRIGGER LEVEL to set the trigger level to 0 V.
4) Press CH1  BW Limit and use to set the bandwidth limit to “200 M”.
5) Output a Sine with 1 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
6) 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 Vrms1.
7) Output a Sine with 200 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
8) Rotate HORIZONTAL
SCALE to set the horizontal time base to 5 ns.
9) 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.
10) Calculate the amplitude loss: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1) and
compare the result with the specification. At this point, the amplitude loss should be within
the specification range.
11) Output a Sine with 400 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
12) Rotate HORIZONTAL
SCALE to set the horizontal time base to 5 ns.
13) 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 Vrms3.
