If no remote is detected, the instrument continues testing 1s after start button is
pressed. In this case the operator must ensure that the cable end is open.
5.3.13 Impedance
Impedance is a characteristic of the cable. In general the characteristic impedances in
high frequency systems must be matched to ensure a regular data flow.
Every change in impedance along the link will cause a reflection and decrease the
signal strength on the receiver end.
A change in impedance can occur if using unproper cables, cable components or the
cable is damaged.
Test procedure:
Make sure that the Remote unit is connected on the far end of the unit under test.
Select and run Impedance test. After the Remote unit is connected and the test is
completed, the results, Pass/Fail information (if a limit is applied) and the limit are
shown on the display. Following actions can now be performed:
ESC key:
return to Single Test main screen
TEST:
repeat the test.
