QSICOS Supports:
Calculation of Coefficients for the
– Impedance Filter (IM) for return loss calculation (please note that the IM filter
coefficients are different for the PEB 2466 and for the PEB 2465. QSICOS
calculates the programming bytes for the SICOFI-4 IOM version PEB 2465. These
bytes have to be converted with an additional tool to get the required PEB 2466
programming bytes. The conversion tool QSUCCONV.EXE is part of the QSICOS
software package.)
– FRR and FRX-filters for frequency response in receive and transmit path
– AR1, AR2 and AX1, AX2-filter for level adjustment in receive and transmit path
– Trans Hybrid Balancing Filter (TH) and
– two programmable tone generators (TG 1 and TG 2)
Simulation of the PEB 2466 and SLIC System
with fixed filter coefficients allows
simulations of tolerances which may be caused e.g. by discrete external components.

Calculation of the PEB 2466 and SLIC system Stability
. The IM-filter of the
PEB 2466 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 2466 and
SLIC combination is calculated. If the real part of the system input impedance is
positive, the total system stability can be guaranteed.
