Measurement Menu - Fracarro KSTT Instrucciones De Funcionamiento

The following is the COFDM (OUTPUT) menu in detail:
For the correct use, see paragraph 9 "INDICATIONS FOR PROGRAMMING".
OUTPUT FREQ. – sets the output frequency according to the channel (setting the country and the output chan-
nel) or according to the MHZ frequency (setting the bandwidth and the MHz frequency).
The following are the parameters that can be set from the OUTPUT menu of the COFDM modulation. FEC – sets
the parameter relevant to FEC (Forward Error Correction) among the possible choices (1/2, 2/3, 3/4, 5/6, 7/8).
GUARD INTERVAL – sets the guard interval among the possible choices (1/4, 1/8, 1/16, 1/32).
CARRIERS NUM. – sets the number of carriers between 2K and 8K.
CONSTELLATION – sets the constellation, QPSK, 16QAM or 64QAM, with which the carriers are modulated.
SPECTRUM – regulates the spectrum as NORMAL or REVERSED according to the reception instrument that
might work only in one of the two modes. Usually the "NORMAL SPECTRUM" setting is used.
LEVEL – regulates the output level on a scale between 0 and 15 to which a STEP equal to 1dB corresponds. Set-
ting the level to OFF, the output signal is disabled. The OFF output level can be set only during the normal opera-
tion and not when the SINGLETONE function is activated.
SINGLETONE – allows the use of a single tone at the input to facilitate the measurement of the output level. When
the SINGLETONE function is activated, no other channels can be inserted.
