New Multi-Channel Lock-in Amplifier from Signal Recovery2013-03-26
Until the introduction of the Model 7210, instruments have been restricted to a single signal channel, allowing only one, or at most two, signals to be measured at any one time. The Model 7210, with its use of new technology, allows up to 32 signals to be measured simultaneously. What is more, units can be linked together to give more detection channels. For example, four units give 128 channels, while sixteen would give 512 channels.
This technological development opens new research avenues and experimental arrangements. A typical use of this instrument would be in simultaneous spectroscopy experiments. In such experiments, a sample would be excited using a known frequency and multiple detectors would provide emission/absorption measurements at each required wavelength.
