Analog-to-digital recorder (ADR) for data acquisition of single-event fast-flowing processes
Fast ADR is an electronic acquisition device using four 50 MSa/s flash analog-to-digital converters (ADCs) with time-interleaved sampling to record single-shot analog waveforms at a total sample rate of 200 MSa/s. The samples digitized by the ADCs then are temporarily stored in a buffer static memory before sending to a PC through the CAMAC bus controller.
- Sampling rate: 200 MHz
- Sampling period: 5 ns
- Resolution: 6-bit
- Input dynamic range: 5V
- Input impedance: 50 Ohm
- Buffer RAM: 256 x 6-bit
- Main logic: ECL
- Interface: CAMAC bus
- Design: CAMAC module 2M-wide
- PCB: single-board 2-layer
The module was developed for the The Institute of Electrophysics of the Ural Branch of the Russian Academy of Sciences to acquire the events occurring in high-current pulse devices, where typical process looks like an explosion of microseconds range.
The device was presented at the International Symposium on Problems of Modular Information Computer Systems and Networks.
