Flow Id. (Hex) 4.5.4.1.1.2
Identification of the Spectrum data flow. This value is reported in all TCP-IP
messages transmitted over the Spectrum Analysis Data port (SPA). Enter any
hexadecimal value from 0 to FFFFFFFF
Identification of the Vector Analysis data flow. This value is reported in all
TCP-IP messages transmitted over the Vector Analysis Data port (VEC). Enter
any hexadecimal value from 0 to FFFFFFFF
Matched Filter 4.5.4.1.1.3
Bit synchronizer filter. Satellite-dependent parameter:
Integral
Integral & Dump
Raised Raised Cosine (See Roll-off)
Root Raised Root Raised Cosine (See Roll-off)
Custom Custom filters (See Fir Cust. Nb)
GMSK GMSK filters (See BT)
SOQPSK SOQPSK filters (See SOQPSK Norm)
Filter roll-off factor: enter any value from 0.1 to 1.0.
FIR custom Number: enter any value from 1 to 1000.
GMSK Filter BT factor: 0.25 or 0.5.
MIL MIL standard filter
TG IRIG standard filter (IRIG standard 106-04)
A CCSDS A-type filter (CCSDS 413.0-G-1)
B CCSDS B-type filter
Select asymmetrical FIR coefficients, else symmetrical FIR coefficients are
applied.
Select complex FIR coefficients, else real FIR coefficients are applied
(dependent of the other FIR characteristics selections).
Select odd FIR coefficients, else even FIR coefficients are applied.
Select the sample rate of the FIR filter as 4 time the symbol rate, else 2 time the
symbol rate is applied.
Select the DEAF mode (Digital Equalization Automatic Filter).
Select the algorithm of the DEAF function. It is recommended to use the LMS
algorithm for the reception of frequency non symmetrical signals.
Select fast DEAF computation.
Select the automatic cross-polarization compensation function.
