Thiết bị thu chuyển đổi tín hiệu ITECH Instruments quadADC
The quadADC is an Embedded Linux based high performance ADC and multi-channel analyzer. It connects to the 0-10 V unipolar signal coming from the main amplifier, analyzes the signal using a 1 μs sliding-scale ADC and stores the events in a pulse-height spectrum with up to 65536 channels.
The quadADC connects to the PC using Ethernet (TCP/IP) and USB. Due to the TCP/IP protocol used the quadADC can be connected locally but also over the Intranet or Internet allowing an arbitrary distance between PC and detector.
The quadADC also features external start/stop inputs, several sample changer inputs and outputs (TTL), USB-Host and RS-232 interfaces for external instruments control and supports several trigger signals.
The quadADC not only offers PHA acquisition but also list and multi spectrum scaling modes. In list mode, the data includes a time stamp (0.5 μs timer resolution) which can be used to detect coincidences between several detectors when analyzing the data.
The list-mode based architecture also makes it possible to acquire spectra for gate/PUR anticoincence and gate/PUR
coincidence simultaneously.
