A.3. Overview of an R9 Control
The Panels labeled Value (A), Offset DAC (B), and Oscillation Amplitude (C) have identical structures.
This structure is referred to as an R9 Control. An R9 Control is a firmware construction that allows the
parameters of R9 components to be changed in a safe and controlled manner. Once this basic structure
is understood, most of the controls that appear to be complex are reduced to simple and intuitive controls.
For this example, CH1 Drive is used to output the Bias. To set the Bias voltage in Hardware Space, the
desired value is entered in the Value data entry box (1) in the Value Pane (A). The current value shown
in this example is 1 V. If a value of 2 V is now entered in the Value data entry box, the settings of the
other parameters in the Value R9 Control will determine how the Bias voltage moves from 1V to 2V.
The Mode (2) dropdown box in this example is set to Set Value (Hard Acceleration). That means the
voltage will immediately jump from 1 V to 2 V. Other choices in the Mode dropdown box are Sweep
PTGs. This stands for Polynomial Time Generator. This is a firmware construction that is used as a
timing signal to ramp voltages and signals.
