Oscillator Control Board

The Oscillator control board has the Microcontroller and all the control logic to generate a
programmable sine wave reference of the correct amplitude and frequency. It includes all the
control logic to respond to user commands from the front panel or the remote control
interface. It also updates the displays to show the programmed settings and current
measurements. Refer to Figure 5-2 for a block diagram.
When the output is programmed above 5.0 volts, the multicolor LEDs, DS10 and DS9, on the
oscillator board will illuminate.
