USER'S MANUAL. MO-170
IF Mode: By using this function, the user can select generating a COFDM signal or
a single tone. A single tone can be useful for accurate alignment or testing of
external components. The available options are:
• COFDM: Generate a COFDM DVB-T signal
• TONE MAX: Generate a single tone at the maximum level available from the
MO-170.
• TONE RMS: Generate a single tone at an RMS level equal to the RMS level of the
modulated COFDM signal.
Error List: During the continuous operation of the MO-170, the first 16 errors
detected are stored as a reference to identify problems. Usually, no errors are
generated, and the display should be as follows:
MENU: back PUSH: select TURN: next/prev.
NO ERRORS
But, during operation, two different kinds of errors are possible (See section "4.11
Error information"):
• Errors generated when the modulator is not locked to the selected TS input.
These are usually temporary errors related to input transport stream transitions or
invalid TS bit rates.
• Errors generated due to a circuit failure. When this kind of errors persists, the
instrument must be serviced in a PROMAX official center.
See section 4.11 for an explanation of the format used to display the errors.
Clear Errors: select this function to clear the internal error counter and errors list
explained formerly. The possible selections are:
• NO
