T o verify component reliability , capacitor manufacturers need to test capacitor insulation
resistance at dierent voltage levels . The 4-channel conguration permits simultaneous
testing of four capacitors with dierent test voltages . This testing technique reduces the
investment cost for instruments to 25% when compared to a single channel instrument.
The 4349B's 11 ms 4-channel simultaneous measurement improves the test throughput on
capacitor production lines .
When insulation resistance testing for capacitor manufacturers , capacitor charge time is
a key factor in slowing down measurement speed. The 4349B's front-end has a 1 k input
resistance to reduce the capacitor's charge time , and thus increases test throughput.
The contact check function veries that the signal path between the handler and the DUT s
is optimal for a measurement. Contact checking maintains automatic handler/DUT integrity
while keeping system throughput high.
System Integration
Built-in comparators for all four channels and the GPIB/handler interface make system
integration with automatic handlers and computers a fast and clean process .
Note
The 4349B has no test voltage source so an external voltage source is required
to make resistance measurements . (The 4349B converts current measurement
data into resistance using the test voltage data entered into memory .)
