Variable Gain Current Amplifier DDPCA-300

Variable Gain Current Amplifier DDPCA-300

Low-noise transimpedance amplifier

■ Input noise: minimum 0.2 fA/√Hz * Peak-to-peak: 0.4 fA ■ Gain can be manually or remotely changed from 10^4 to 10^13 V/A ■ Covers a wide dynamic range of over 240 dB, capable of handling current values from sub-fA to mA ■ Compact housing allows for installation near the signal source, reducing noise from long cabling ■ Various filters are built-in to optimize the amplifier's bandwidth according to the signal state, allowing for S/N ratio and measurement speed settings based on the application ■ Even when the gain is set to maximum, it maintains sufficient measurement speed to measure femtoampere currents in real-time ■ At femtoampere levels, measurement errors and baseline shifts due to drift or offset currents are more likely to occur, but the DDPCA-300 excels in long-term stability and minimizes drift to the extreme.

Ultra-Low Noise Fixed Gain Current Amplifier LCA Series

Ultra-Low Noise Fixed Gain Current Amplifier LCA Series

Very low noise preamplifier module.

■ Unlike desktop amplifiers, it eliminates the deterioration of the S/N ratio caused by cable capacitance and noise pickup. ■ Signal processing and measurement after the preamplifier do not affect the S/N ratio. ■ While minimizing the narrowing of bandwidth, it achieves significantly higher gain and ultra-low noise compared to conventional current pressure converters. ■ No special connections or frequency corrections are required. ■ Hand width and frequency response are unaffected by source capacitance up to 10nF, preventing gain peaking.

Raman fiber amplifier (Raman amplifier)

Raman fiber amplifier (Raman amplifier)

■High output: ≤700mW ■Operating temperature range: -20 to 60℃ ■Modular, benchtop lineup available

◆RS232/RJ45 interface, with dedicated software The Beogold Raman amplifier is a high-output Raman amplifier with a maximum output of 700mW. By combining different types of pump lasers and fiber types, it achieves flat gain and low noise optical signal amplification across the entire C-band. To ensure laser safety, it is equipped with an auto-shutdown mechanism that automatically stops the laser output in the event of accidents such as fiber breakage or line aging. It has built-in drive and logic circuits, and all configuration information, such as pump laser temperature and module temperature, can be monitored in real-time by the upper-level computer software.
