Bandwidth Limit Test
Specification:
Amplitude Loss
-3 dB to 1 dB
Explanation:
Amplitude Loss (dB) = 20×lg
(Vrmsn/Vrms1)
. Wherein, Vrmsn represents Vrms2 and Vrms3.
Test Device: Fluke 9500B
Test procedures:
1) Connect the active head of Fluke 9500B to CH1 of the oscilloscope.
2) Set the output impedance of Fluke 9500B to 1 MΩ.
3) Configure the oscilloscope:
a) Press CH1 in the vertical control area (VERTICAL) at the front panel to
enable CH1.
b) Rotate VERTICAL SCALE to set the vertical scale to 100 mV/div.
c) Rotate HORIZONTAL SCALE to set the horizontal time base to 500
ns.
d) Rotate HORIZONTAL POSITION and VERTICAL POSITION
to set the horizontal position and vertical position to 0 respectively.
e) Rotate TRIGGER LEVEL to set the trigger level to 0 V.
4) Press CH1  BW limit to enable the function of the bandwidth limit.
5) Output a sine waveform with 1 MHz frequency and 600 mVpp amplitude from
Fluke 9500B.
6) Enable the root mean square measurement function of the oscilloscope.
Read and record Vrms1.
7) Output a sine waveform with 20 MHz frequency and 600 mVpp amplitude
from Fluke 9500B.
8) Rotate HORIZONTAL
SCALE of the oscilloscope to set the horizontal
time base to 50 ns.
9) Read and record root mean square value Vrms2.
10) Calculate the amplitude loss and compare it to the specification: Amplitude
Loss (dB) = 20×lg
(Vrms2/Vrms1)
. Amplitude loss should be in the range of the
specification at this point.
11) Output a sine waveform with 50 MHz frequency and 600 mVpp amplitude
from Fluke 9500B.
12) Rotate HORIZONTAL
SCALE of the oscilloscope to set the horizontal
time base to 20 ns.
13) Read and record root mean square value Vrms2.
14) Calculate the amplitude loss and compare it to the specification: Amplitude
Loss (dB) = 20×lg
(Vrms3/Vrms1)
. Amplitude loss should be lower than -3 dB at
this point.
15) Keep other settings of the oscilloscope unchanged and set the vertical scale
to 200 mV/div.
16) Output a sine waveform with 1 MHz frequency and 1.2 Vpp amplitude from
Fluke 9500B.
