Performance Verification Test
5. Turn off CH1. Measure the resistances of CH2, CH3, and CH4 respectively using the
method above and record the measurement results.
Impedance test when the input impedance is 50 Ω
1. Connect the active head of Fluke 9500B to CH1 of the oscilloscope, as shown in
Figure 5.1
2. Configure the oscilloscope:
a. Use the method illustrated above to turn on CH1.
b. Set the input impedance of CH1 to 50 Ω.
c. Set the vertical scale of CH1 to 100 mV/div.
3. Turn on Fluke 9500B; set its impedance to 50 Ω and select the resistance
measurement function. Read and record the resistance measured.
4. Adjust the vertical scale of CH1 to 500 mV/div; read and record the resistance
measured.
5. Turn off CH1. Measure the resistances of CH2, CH3, and CH4 respectively using the
method above and record the measurement results.
