產(chǎn)品名稱：可變增益電流放大器DHPCA-100 產(chǎn)品型號(hào)：DHPCA-100 產(chǎn)品品牌：德國FEMTO 產(chǎn)品簡介： Bandwidth and Frequency Response The DHPCA-100 provides an optimum combination of gain and bandwidth. At the gain setting of 103 V/A it provides an extraordinary high 3 dB bandwidth of 200 MHz and even at the highest gain setting of 108 V/A the upper cut-off frequency is still an excellent 220 kHz. For those applications not requiring the full bandwidth the unit has a switchable 10 MHz and 1 MHz low pass filter to minimize broadband noise. 技術(shù)參數(shù)： Transimpedance Gain from 102 to 108 V/A Bandwidth up to 200 MHz Rise Time down to 1.8 ns Internal Signal Filters Adjustable Bias Voltage Manual and Remote Control 主要特點(diǎn)： The Ultimate High Speed Current Amplifier The DHPCA-100 variable gain transimpedance amplifier is the perfect choice for applications that require the conversion of small electrical currents into usable voltages at bandwidths up to 200 MHz. It is ideally suited for DC and AC measurements up to 200 MHz, time resolved measurements down to the ns-region and as the preamplifier for fast photodetector signals. The DHPCA-100 offers many features including variable gain from 102 to 108 V/A, switchable AC/DC-coupling, adjustable offset for baseline correction, adjustable bias voltage for use with fast photodiodes, switchable 10 MHz and 1 MHz low pass filters and the capability of both manual and remote control. With its rugged and compact EMI shielded case the DHPCA-100 is the ideal universal high speed amplifier for a broad range of applications. 配套用的電源:電源：PS-15-25-L 7級(jí)可變增益102~108V/A，200MHz通帶上限，1.8ns小上升時(shí)間，可變換信號(hào)過濾器和直流交流耦合器，可調(diào)Bias電壓和偏置電壓，手動(dòng)操作和遠(yuǎn)程控制，適用于快速光探測器、示波器器的前級(jí)放大，射頻鎖相和實(shí)驗(yàn)室的一般性應(yīng)用。
