3.2.3
The VINETIC
accomplish a variety of diagnostic functions that can be used in production tests. Various
test loops and measurement features are completing this tool suite.
Preliminary Product Overview
The DC loop resistance can be determined by supplying a constant DC voltage
V
– Leakage current Tip/Ring
– Leakage current Tip/GND
– Leakage current Ring/GND
Capacitance measurements can be performed by using the integrated ramp
generator function. Loading a capacitor C
in a constant current which is proportional to C
– Line capacitance Tip/GND
– Line capacitance Ring/GND
Three analog input pins per voice channel can be used for direct and differential
measurement of external voltages.
