QM1004-2-18 Combined RF Upconverter/Downconverter system
The QM1004-2-18 Combined RF Upconverter/Downconverter has been equipped with Option -100,
which adds Local Oscillator (LO) sources, making the QM1004-2-18 a self contained system, requir-
ing only the externally applied RF or IF signals for proper operation. Option -200 shifts the IF frequency
range from 750-1250MHz to 50-550MHz. The Local Oscillators (LOs) in the QM1004-2-18 are locked to
a common internal 100 MHz reference. The user has the option of supplying their own reference through
the BNC connector located on the back panel of the QM1004-2-18.
