Bandwidth Limit Test
The bandwidth limit test verifies the 20 MHz bandwidth limit function of the oscilloscope by testing the
amplitude loss of the oscilloscope under test at the bandwidth limit.

-3 dB, all-channel mode
Note
[1]
: Amplitude Loss (dB) = 20 × lg (Vrms2/Vrms1). Wherein, Vrms1 is the measurement result of amplitude
effective value at 1 MHz; Vrms2 is the measurement result of amplitude effective value at the bandwidth limit.

Test Procedures
1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in the figure above.
2. Turn on Fluke 9500B and set its impedance to 1 MΩ.
3. Configure the oscilloscope:
1) Press CH1 in the vertical control area (VERTICAL) on the front panel to turn on CH1.
2) Press CH1  Probe to set the probe attenuation ratio to "1X".
3) Rotate VERTICAL SCALE to set the vertical scale to 100 mV/div.
4) Rotate HORIZONTAL SCALE to set the horizontal time base to 500 ns/div.
5) Press HORIZONTAL POSITION and VERTICAL POSITION respectively to set the
horizontal position and vertical position to 0.
6) Press TRIGGER LEVEL to set the trigger level to 0 V.
4. Output a Sine with 1 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
5. Press MENU  Vrms at the left side of the screen of the oscilloscope to turn on the effective
value measurement function. Read and record Vrms1.
6. Press CH1  BW Limit to set the bandwidth limit to "20 M".
7. Output a Sine with 20 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
