method above and record the test results.
2. DC gain accuracy test when the input impedance is 1 MΩ
1) Connect the active signal terminal of Fluke 9500B to CH1 of the oscilloscope, as shown in the
figure above.
2) Set the input impedance of Fluke 9500B to 1 MΩ.
3) Output a DC signal with +3 mV
DC
voltage (Vout1) via Fluke 9500B.
4) Configure the oscilloscope:
a) Turn on CH1.
b) Set the probe attenuation ratio to “1X”.
c) Set the input impedance of CH1 to 1 MΩ.
d) Repeat d) to g) in step 4) in DC gain accuracy test when the input impedance is
50 Ω.
5) Test the relative error of each scale of CH1 (add the tests of 2 V/div and 5 V/div) according to
steps 5) to 9) in DC gain accuracy test when the input impedance is 50 Ω and record
the test results.
6) Turn off CH1. Test the relative error of each scale of CH2, CH3 and CH4 respectively using the
method above and record the test results.
