E.V.I.L.
We have developed an Electronically Variable Interactive Lock-box (E.V.I.L.) to act as prototyping hardware.
Enabled by the Xilinx Spartan 3E FPGA
Max. Input/Output voltages +/-10 V
Supply voltages: +/-15 V
A current implementation is a dual-channel PI controller which we use for locking lasers to cavities. Our Python based software interface allows for convenient operation from any computer.
Bandwidths: 500 kHz (fast controller), 70 kHz (slow controller).
