UK-based distributor Laser Components has introduced a new lock-in amplifier from German manufacturer Femto Messtechnik. The SC-LIA-S multiple-channel lock-in amplifiers are based on the company's LIA-BV-150-H model, Board Series lock-in amplifier, and are now available as a standard 19-inch rack system. The SC-LIA-S can be tailor-made to suit specific requirements, with options including 50-120Hz, with 5-10kHz working frequency, integrated sine reference signal module, control interface either common for all installed channels, individual for each channel, or none. The option for local or remote control via an 18-pin Sub-D connector is also offered. The device is suitable for applications requiring multi-channel lock-in detection.
