Can be used alone by DC power supply FET input voltage preamplifier SR550/SR552
Cons Technology Co., Ltd.
About This Product
It is a transformer staplap dream that reduces noise. DC power supply can be used alone.
■ Characteristics
The preamplifier, which is also used in the audio field, is also rephrased as a current amplifier in the field of measurement analysis equipment. If the signal to be measured is weak and the impedance is high, it will be more likely to be affected by noise, etc., and it will be difficult to measure accurate signals. Therefore, by installing a preamplifier between the signal source and the measurement device, it is possible to clearly measure even a weak signal.
As for the performance required for measuring equipment, it is very important to be able to measure excellent signals with S/N ratio. The preamp has a role in amplifying the signal to be input to increase the accuracy of measurement. One of the factors that hinders accurate measurements includes various noise from inside or outside the equipment, but through a preamplifier can greatly reduce the effects of noise.
If you want to realize a low -noise environment, you may be used in combination with a lock -in amplifier. There are also types of preamplifiers, such as differential input and isolation input, so you need to choose the level of the signal you want to amplify and the frequency band.
■ Main use
Preamplifiers are used in a wide range of fields in combination with various measurement devices. Cons Technology handles each model of SR560, SR570, SR445A, SR550, SR552, SR555, SR555, and SR556 depending on the application.
