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.

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 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.
