VKINGING VK302 1Hz-1Mhz 20-60db Low Noise Preamplifier VK30X Series Low Noise Voltage Preamplifier

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.
