5-6 Performance Verification WR6K Rev. D
5.4.2 External Trigger Input Impedance
a. DC 50Ω
Recall Input Impedance - 50 ohm ext x1.lss or configure the DSO :
Select Setup trigger
Trigger on : EXT
Impedance : DC 50Ω
Connect the DMM to External, and measure the input impedance, reverse the
meter leads and measure the input impedance.
Average these two numbers and record the input impedance in Table 2, and
compare the result to the limit in the test record.
b. Ext DC 1MΩ Input Impedance
Recall Input Impedance - 1 Mohm DC Ext x1.lss or configure the DSO :
Select Setup trigger
