– Return Loss
– Frequency responses in receive and transmit path
– Transhybrid Loss
PEB 2465 adjust the total system impedance by making a feedback loop. Because
the line is also a part of the total system, a very robust method has to used to avoid
oscillations and to ensure system stability. The input impedance of the PEB 2465 and
SLIC combination is calculated. If the real part of the system input impedance is
positive, the total system stability can be guaranteed.
