Low Frequency Voltage Amplifier (DLPVA Series)

Low Frequency Voltage Amplifier (DLPVA Series)

A DC voltage amplifier with low temperature drift of offset input voltage and high accuracy.

- No adjustment of offset voltage is required even at a gain setting of 100dB, making it optimal for DC coupling. - The gain setting and amplifier bandwidth, which are very important parameters for measuring high-speed signals and pulses, are independent of each other. - The bandwidth remains constant at 100kHz with a 3dB maximum gain setting. - The cutoff frequency can be adjusted up to a maximum of 1kHz, allowing for the reduction of wideband noise. - Parameters such as gain setting and bandwidth can be easily operated directly via local switches. - The selected gain setting is displayed with an LED. - TTL bits corresponding to each switch are available for remote operation. * Mixed operations are also possible. - Six different models are available, including single-ended or true differential inputs, bipolar or FET.

Wideband Voltage Amplifier (HVA Series)

Wideband Voltage Amplifier (HVA Series)

Even with different gain settings, the bandwidth remains constant, making it very useful for measuring fast signals and pulses.

■ The output offset can be adjusted, allowing for true DC coupling, which avoids decoupling due to the oscilloscope's AC settings and suppresses measurement undershoot and baseline. ■ The minimum input noise is low at 0.9nV/Hz, providing a high S/N ratio in small signal amplifiers. ■ It can accurately amplify pulses with varying widths from microseconds to milliseconds, such as digital codes or transients. ■ To achieve optimal S/N performance, an amplifier with sufficient bandwidth corresponding to the required signal bandwidth is necessary. ■ If the bandwidth is unnecessarily high, wideband noise increases. ■ The HVA series offers three models with different cutoff frequencies, allowing you to choose the optimal model based on measurement conditions.

Variable Gain High-Speed Gigahertz Amplifier (DUPVA Series)

Variable Gain High-Speed Gigahertz Amplifier (DUPVA Series)

Designed for high-speed and precise measurements requiring a high dynamic range.

■ Gain can be set via a local selector or optical isolator, or a remote control interface. ■ The frequency response is independent of gain, and since the variation in rise time is small even when changing the gain setting, accurate time-resolved measurements are possible. ■ The frequency response is very flat across the entire frequency range, allowing for pulse or transient measurements without gain peaking.

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 built-in filters optimize the amplifier's bandwidth according to the signal state, allowing for settings of S/N ratio and measurement speed 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 and offset currents are more likely to occur, but the DDPCA-300 excels in long-term stability, minimizing drift to an extreme degree.

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 the bandwidth, it achieves a 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.
