Proper Operation
The 965DSP Subscriber Loop Analyzer measures 
extremely low noise levels and requires proper 
handling of the test leads to ensure consistent 
measurements. Extend the test leads away from the 
965DSP  when conducting DSL tests, and make sure 
that the red and black leads are kept as close together 
as possible to minimize RF noise pickup. 
Note:  Do not attempt to conduct DSL noise or loss 
measurements while the external DC charger is 
connected.
