NsMargin
(Noise Margin) Signal to Noise Ratio margin
OMI
Optical modulation index
PER
The Packet Error Ratio (Packet Error Ratio) displays the number of incor-
rectly received data packets relative to the total number of transmitted
packets (after Viterbi) .
QEF
(Quasi Error Free) Bit error rate equals 2.00e-4
Noise level
Sum of noise factor and thermal noise floors. Noise is created by physi-
cally caused molecular motion in electrical conductors.
RMS
(Root Mean Square) Method of a square mean value determination
S/N
(Signal to Noise) Difference between the wanted signal and the noise level
in dB; S/N ≈ C/N + 1,5; see also C/N
SPTS
Single Program Transport Stream.
TSID
(Transport Stream ID) Transponder/multiplex ID
VBR
(Variable Bit Rate) is used for MPTS measurements, cf. CBR
VPID
(Video Packet Identifier) Video reception parameters in the MPEG data
stream
