About This Product
■ SR810 (1st place phase) ・ SR830 (2nd phase)
A cost -effective digital lock -in amplifier equipped with DSP (Digital Signal Prosessor).
■ Principles and mechanism of lock -in amplifier
In fields that require small signals, peripheral noise is a major problem. Lock in amplifiers are used to accurately detect a small signal so that the signal is not buried in the noise, such as when the light measurement or a very small resistance value is detected.
Synchronization and filter technology are applied to detecting signals using lock -in amplifiers. This is a mechanism to modulate the small signal so buried in the noise, amplify it to a level that can be detected, and then extract only the necessary signals through the filter.
The purpose of using a lock -in amplifier is to keep the signal to be detected as much as possible from the noise. To do so, the signal to be detected is modulated, separated from the noise frequency, and then cut the noise or other unnecessary frequency with filter, so that only the signal to be requested can be detected accurately.
■ Main use
・ Detection of extremely small resistance value
・ Detection of light absorption and reflection
・ Detection of the directional characteristics of the light source
・ Detection of thermal conduction characteristics
・ Low -temperature physical research
Recently, digital lock amplifiers with high -performance digital signal processing (DSP) have become the mainstream from analog lock -in amplifiers.
Cons Technology handles 10 models: SR860, SR865A, SR810, SR850, SR850, SR124, SR2124, SR510, SR530, and optical interface controller SX199.
