A high-voltage (HV) power supply device outputs an output voltage based on a control signal generated by dual analog / digital feedback loops. The control signal is determined at least in part by an error amplifier that receives a measurement signal attenuated proportionally to the output voltage and an output signal from a digital-to-analog converter (DAC). The ADC also receives the measurement signal and transmits it in digitized form to a digital processor. The digital processor calculates a digital DAC data signal based on the measurement signal and a digital setpoint input signal corresponding to a setpoint voltage value desired to be output from the high-voltage source. The DAC receives the DAC data signal and converts it into a DAC output signal that is transmitted to the error amplifier.

Embodiments of the present disclosure include techniques for moving data between electronic system components using buffers. A digital processor stores data generated in response to a series of commands in a first buffer. Commands are received with a reference to a second buffer. The digital processor tracks the last location that a data result was stored in the first buffer. When a data result fills the buffer, the remaining data is automatically stored in the second buffer. Downstream devices may empty full buffers. A client may receive an indication that a buffer is empty and subsequently send commands with a reference to empty buffer.
