1.1.2 FUNCTIONAL
The MITEQ 9300 Series Converter combines a state of the art
communications converter with microprocessor-controlled digital
circuitry to provide flexibility and convenience for the station
operator.
The converter translates the 3.7-4.2 GHz frequency band to the
70 ±20 MHz output frequency band. Phase noise, amplitude
flatness, group delay, and spurious outputs have been given
optimum consideration to provide the user with a transparent
frequency conversion for all video and data applications.
RF frequency may be selected from the front panel in 125 kHz
increments. Non-volatile memory allows the operator to store up
to thirty channel frequencies.
Remote operation is available via the RS485 (serial) interface.
The status of the converter's functions and alarms may also be
read through the remote interface (optional). Device address is
selectable at the rear panel.
Relays are provided for summary alarm output which may be used
for monitoring at a remote console and for redundant switching.
AC voltage input is selectable at the rear panel (100, 120, 220,
230/240VAC).
