仪器简介： 
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. 

技术参数： 
互阻放大倍数:10二次方到10八次方 V/A 
增益精度:±1% 
等效输入电压噪声:2.8nV/√Hz; 
增益设置:低噪声模式,高速模式; 
输出电压:±1V 
输出阻抗:50Ω 
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 

主要特点： 
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 **s. 
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. 


7级可变增益102~108V/A，200MHz通带上限，1.8ns较小上升时间，可变换信号过滤器和直流交流耦合器，可调Bias电压和偏置电压，手动操作和远程控制，适用于**光探测器、示波器器的前级放大，射频锁相和实验室的一般性应用。
