Performance characteristics
In addition to the general charge amplifier function, the multi-channel charge voltage filter integration amplifier also has anti-aliasing filtering and voltage amplification functions.
1. Multi-channel microcomputer control, digital display of turning frequency, accurate and clear.
2. In addition to the performance of a universal charge amplifier, each channel also has an anti-aliasing filter, which is particularly suitable for use as a preamplifier in a signal processing system.
3. With voltage input function, the instrument can be equipped with a voltage output sensor.
4. With one-time integration function. With a piezoelectric acceleration sensor, in addition to measuring acceleration, you can also measure speed; with a speed sensor, in addition to measuring speed, you can also measure displacement.
5. Small size, light weight, stable and reliable.
