Bandwidth Test
The bandwidth test verifies the bandwidth performance of the oscilloscope by testing the amplitude
loss of the oscilloscope under test at full bandwidth.
Specification
Bandwidth
Amplitude Loss
[1]
150 MHz
-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 and Vrms2 is the measurement result of amplitude effective value at full bandwidth.

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; set its impedance to 1 MΩ.
3. Configure the oscilloscope:
1) Press 1 in the vertical control area (Vertical) on the front panel to enable CH1.
2) Press 1  Attenuation to set the probe attenuation ratio to "1X".
3) Press 1  Impedance to set the input impedance of CH1 to 1 MΩ.
4) Set the horizontal timebase to 500 ns/div.
5) Set the vertical scale to 100 mV/div.
6) Set the horizontal position and vertical offset to 0.
7) Set the trigger level to 0 V.
4. Output a Sine with 1 MHz frequency and 600 mVpp amplitude via Fluke 9500B.
5. Press Measure  Add  Category to select "Vertical". Then, select "VRMS" measurement
parameter to enable the effective value measurement function. Read and record Vrms1.
6. Output a Sine with 150 MHz frequency (the setting value is different for different models of the
oscilloscope under test; please refer to Table 2-2) and 600 mVpp amplitude via Fluke 9500B.
