Datasheet

Overview

The Tunable Filter Controller Development Kit, originally developed by Micron Optics, is an electronic piezoelectric actuator driver designed for the FFP Tunable Filter (TF or TF2) or the FFP Scanning Interferometer. It supplies a user-selectable symmetric triangle wave to the PZT-based device, allowing it to be tuned across its scan range.

The kit can be used in several modes of operation, including as a manual DC voltage driver or as a DC + AC voltage driver with bias, amplitude and frequency controls. It is intended for first-time users of fiber Fabry-Perot filters learning filter technology and operation, and as a lab bench tool for research into advanced tunable filter capabilities. The manufacturer states that it is intended for laboratory demonstrations and not for field applications.

Control and software

The development board has three pushbuttons and an integrated display showing the active frequency and voltage, so it can be operated without a PC. Over Ethernet, it can be controlled with a Windows application or through LabVIEW 2017 and Python v3 APIs, which include example programs. Drive and sync/trigger signals are provided on SMA connectors.
