Description:
It
is a low noise voltage preamplifier. Using low-noise amplification
unit, optimized low-noise power supply, etc., it boasts high precision,
ultra-low noise, high suppression ratio, wide measurement range and low
temperature drift. Thus, it can be widely used for weak signal
measurement.
The preamplifier adopts all-metal shielding, and its
internal core unit is shielded separately again to isolate the maximum
scale of interference. Its power supply unit adopts a wide input range
and high reliability design. It is moisture-proof and shockproof and can
adapt to the application of strong industrial interference.
Features:
- High precision, low noise and small frequency response error
- With precision devices, the preamplifier boasts high stability
- Metal shielded shell with strong anti-interference ability
- Adjustable gain and three switchable gains
- With filtering and pass-through switching
- Very wide voltage input range
- BNC input and output for easy connection to various instruments
Application:
- Very weak voltage signal amplification
- Ultrasonic preamplifier
- Photoelectric transmission preamplifier
- High-performance pre-amplification
Package Included:
- 1 x Preamplifier
- 1 x Input lead
- 1 x BNC output cable
- 1 x Power adapter
Adjustable gain and total gain:
-
The gain of the first stage of the amplifier is A1, the gain of the
second stage is A2, and the total gain is Aout. Aout=Al*A2.
- If you
want to achieve the maximum signal-to-noise ratio, the first stage
magnification should be as large as possible. The second stage cannot
change the signal-to-noise ratio. Usually the noise and signal of the
first stage should be amplified at the same time.
