1) LEVEL_=_X_dBuV|dBmV|dBm. The current channel or transponder level is the
X (one decimal place);
2) SNR_=_X_dB. The current value of signal-to-noise ratio is the X value (one
decimal place);
3) V/A1_=_X_dB. The current value of level-to-audio ratio (mono audio subcarrier)
of the analog channel is the X (one decimal point);
4) V/A2_=_X_dB. The current value of level-to-audio ratio (additional audio
subcarrier for stereo broadcasting) of the analog channel is the X (one decimal
point);
5) LOCKED_(X). Synchronization with the channel is set, X - channel parameters in
one of the following formats:
a. Analog/X-Y. Analog channel, X - the color system (PAL, SECAM or NTSC),
and Y – the analog broadcasting standard (B, D, G, H, I, K, L, L', M or N);
b. DVB-C/X/Y. DVB-C channel, X – the constellation type (QAM64, QAM128 or
QAM256), and Y – the symbol rate in MSymb/s (3 decimal places);
c. J.83-B/X/Y. J.83-B channel, X – the constellation type (QAM64 or QAM256),
and Y – the symbol rate in MSymb/s (3 decimal places);
d. J.83-C/X/Y. J.83-C channel, X – the constellation type (QAM64, QAM128 or
QAM256), and Y – the symbol rate in MSymb/s (3 decimal places);
e. DVB-T/X/Y. DVB-T channel, X – FFT type (2k or 8k), and Y – the constellation
type of subcarriers (QPSK, QAM16 or QAM64);
f. DVB-T2/X/Y/PLP=Z. DVB-T2 channel, X – FFT type (1k, 2k, 4k, 8k, 16k or
32k), Y – the constellation type of subcarriers (QPSK, QAM16, QAM64 or
QAM256), and Z – the identifier of the receiving PLP logical steam;
g. DVB-S/X/Y. DVB-S transponder, X – the constellation type (QPSK), and Y –
the symbol rate in kSymb/s;
h. DVB-S2/X/Y/ISI=Z. DVB-S2 transponder, X – the constellation type (QPSK,
8PSK, 16APSK or 32APSK), Y – the symbol rate in kSymb/s, and Z – the
identifier of the receiving ISI logical steam;
i. FM. FM radio;
j. ?. Unknown type channel;
6) UNLOCKED. Synchronization with the channel is lost;
7) MER_=|<|>_X_dB. The current channel MER value is equal/less/more than X
(one decimal point);
8) MARGIN_=|<|>_X_dB. The current value of the noise margin to the quasi-error-
free decoding point is equal/less/more than the X (one decimal point);
9) BER1_=|<|>_X. The current BER value before the decoders is equal/less/more
than X (scientific notation with one decimal point, for example, 1.0E-09). For DVB-
C and J.83-C – BER before the Reed-Solomon decoder, DVB-T and DVB-S –
BER before the Viterbi decoder, DVB-T2 and DVB-S2 – BER before the LDPC
decoder;
10) BER2_=|<|>_X. The current BER value after the first decoder is equal/less/more
than X (scientific notation with one decimal point, for example, 1.0E-09). For J.83-
B, DVB-S and DVB-T – BER before the Reed-Solomon decoder, DVB-T2 and
DVB-S2 – BER before the BCH decoder;
11) BER3_=|<|>_X_(Y_bad_packets). The current PER value at the output of the last
decoder is equal/less/more than X (scientific notation with one decimal point, for
example, 1.0 E-09). Y – the number of uncorrected MPEG packets at the output of
the decoder (that is the accumulative counter in case the averaging is switched on
in the measurement mode settings). For DVB-C, J.83-B, J.83-C, DVB-T and
DVB–S – PER after the Reed-Solomon decoder, for DVB-T2 and DVB-S2 – PER
after the BCH decoder;
12) FATAL_ERROR_(X). The fatal error occurred, X - the error description. Please
contact the Analyzer's manufacturer to fix the error.
