Specifications
A/D conversion part
This is a differential input type high-speed A/D converter. It amplifies and
A/D converts the signal input from various multichannel detectors.
The A/D converters are available 16bits or 12bits.They are switched from
the MDDA software.

Controller
The controller is made up of various multichannel detectors drive circuits,
data storage memory, and computer interface (SCSI interface, RS-232C
interface).
Multichannel detector storage time setting, data transfer, etc. can be easily
performed by issuing commands from an external computer over the SCSI
interface.
