5-8 Performance Verification Rev. D Sept 2007
b. Ext DC 1MΩ Input Impedance
Recall Input Impedance - 1 Mohm DC Ext x1.lss or configure the DSO :
Select Setup trigger
Trigger on : EXT
Impedance : DC 1MΩ
Connect the DMM to External, and measure the input impedance.
Record the input impedance in Table 2, and compare the result to the limit in the
test record.
Recall Input Impedance - 1 Mohm DC Ext x10.lss or Set Trigger Source to
Ext/10.
Repeat the test for all input channels.
Record the measurements in Table 2, and compare the test results to the
limits in the test record.
