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 ideal 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 specified. - The cutoff frequency can be adjusted up to a maximum of 1kHz, which helps reduce wideband noise. - Parameters such as gain setting and bandwidth can be easily and directly operated via local switches. - The selected gain setting is indicated by an LED. - TTL bits corresponding to each switch are available for remote operation, and mixed operations are also possible. - Six different models are available, including single-ended or true differential inputs, bipolar or FET.
Even with different gain settings, the bandwidth remains constant, making it very useful for measuring high-speed 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, enabling 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 and 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 includes three models with different cutoff frequencies, allowing you to choose the optimal model based on measurement conditions.
Designed for high-speed and precise measurements requiring a high dynamic range.
■ Gain can be set via a local selector or optical isolator, or through 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.
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.
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.
