Abstract: In this paper, we present an universal solution for radio frequency (RF) and laser cavities regulation, including piezocontrols and drivers based on MicroTCA.4 electronics. The control electronics consists of an Analog to Digital Converter-advanced mezzanine card (AMC) with an analog rear transmission module (RTM) to downmix and measure the RF signals and a low cost AMC-based Field Programmable Gate Array mezzanine card carrier for fast data processing and digital feedback operation connected to an RTM piezodriver. For the RF cavity regulation, the piezodriver includes additional inputs to use piezoelements as active force sensors. The fine tuning of the laser is carried out using a cavity fiber stretcher. The coarse tuning of the supported optics is done using a piezomotor-driven linear stage. Both channels can be operated using digital feedback controllers. First, results from continuous wave operation of the RF field controller and the cavity active resonance control with the piezotuners are demonstrated. The laser lock application performance using both fine and coarse channel feedbacks is shown and briefly discussed.
