Test Signal
Defines the test signal data.
Use the parameter to measure the bit error rate before the Viterbi decoder with the
BER application, the R&S
ETL measurement receivers, and its serial outputs (clock
and data).
"Test TS Packet"
Standardized packet data used as modulation data in the transport
stream.
To configure the packet structure, select the side tab "Test Signal >
Test TS Packet". See also
Chapter 3.2.3, "Test Signal settings" ,
on page 16.
"PRBS before Conv. Enc."
Pure pseudo-random bit sequence (PRBS) data used as modulation
data with no packet structure. The sequence is inserted before the
convolutional encoder. PRBS data conforms with
ITU-T O.151 speci-
fication.
To configure the PRBS type, select the side tab "Test Signal >
PRBS". See also
"PRBS" on page 17.
"PRBS after Conv. Enc."
