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.
