High-speed gain variable current amplifier (DHPCA)
The "DHPCA-100" can convert small currents into effective voltage with a bandwidth of up to 200MHz.
- Ideal for DC/AC measurements up to 200MHz, time-resolved measurements down to nanoseconds, and preamplifiers for high-speed detector signals. - Gain: Variable in the range of 102 to 108 V/A. - AC/DC coupling can be changed, and offset for baseline correction as well as bias voltage for high-speed photodiodes can be adjusted. - Features a good balance between gain and bandwidth. - When the gain is set to 103 V/A, it has a high 3dB bandwidth of 200MHz. - The cutoff frequency on the high-frequency side when the gain is set to 108 V/A is 200kHz. - Both manual operation and remote control are possible. - The case is a sturdy and compact EMI shielded enclosure. - Comes with removable 10MHz and 1MHz low-pass filters to eliminate bandwidth noise.
