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.},
