100MHz Bandwidth Limit Test (only for DS2202)
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, as shown in the figure
below.
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 200 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 and use to select “100 MHz” bandwidth limit.
5) Output a sine waveform with 1 MHz frequency and 600 mVpp amplitude from Fluke 9500B.
6) Press MENU Vrms at the left of the screen to enable the root mean square
measurement function of the oscilloscope. Read and record Vrms1.
7) Output a sine waveform with 100 MHz frequency and 600 mVpp amplitude from Fluke
9500B.
8) Rotate HORIZONTAL
SCALE of the oscilloscope to set the horizontal time base to 5
ns.
9) Press MENU Vrms at the left of the screen to enable the root mean square
measurement function of the oscilloscope. Read and record 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 200 MHz frequency and 600 mVpp amplitude from Fluke
9500B.
12) Rotate HORIZONTAL
SCALE of the oscilloscope to set the horizontal time base to 2
ns.
