儀器簡介：

Bandwidth and Frequency Response

The DHPCA-100 provides an optimum combination of gain andbandwidth. At the gain setting of 103 V/A it provides an extraordinary high 3dB bandwidth of 200 MHz and even at the highest gain setting of 108 V/A theupper cut-off frequency is still an excellent 220 kHz. For those applicationsnot requiring the full bandwidth the unit has a switchable 10 MHz and 1 MHz lowpass filter to minimize broadband noise.

主要特點：

The Ultimate High Speed Current Amplifier

The DHPCA-100 variable gain transimpedance amplifier is theperfect choice for applications that require the conversion of small electricalcurrents into usable voltages at bandwidths up to 200 MHz. It is ideally suitedfor DC and AC measurements up to 200 MHz, time resolved measurements down tothe ns-region and as the preamplifier for fast photodetector signals.

The DHPCA-100 offers many features including variable gain from102 to 108 V/A, switchable AC/DC-coupling, adjustable offset for baselinecorrection, adjustable bias voltage for use with fast photodiodes, switchable10 MHz and 1 MHz low pass filters and the capability of both manual and remotecontrol. With its rugged and compact EMI shielded case the DHPCA-100 is theideal universal high speed amplifier for a broad range of applications.
