3. System Block Diagram

A System block diagram for the QM1014 LO Synthesizer Distribution Unit is shown in Figure 1.2. The
microcontroller outputs basic status messages on a 32-character Liquid Crystal Display (LCD) mounted
on the faceplate of the unit. An internal 10 MHz reference clock is phase-locked to all of the internal
LOs, with a BNC-F connector providing the option for LOs to lock to a user-provided 10 MHz external
reference. An additional BNC-F connector forwards the 10 MHz reference back out for use by external
test equipment.
