The ACQ - USB Acquisition Program
The Acq Data Acquisition Program acquires and processes data from specific USB I/O modules designed for this application. The currently supported modules are: 1. USB_ADC_NNNN - ADC I/O modules which interface with Northern Instruments models NS-62x ADCs and Tracor Northern Instruments models TN-12xx ADCs. 2. USB_TMR_NNNN - Timer I/O modules with time-bases of from 100 microseconds (us) to 10 seconds for multichannel scaling applications. The I/O modules are organized into 'chains' of from 1 to 8 modules per chain. The acquisition program supports upto 8 chains. The I/O modules in each chain can be configured for independent operation (i.e. singles mode) where acquired events are channeled through their corresponding I/O module USB connections. The I/O modules in each chain may be combined for multiparameter acquisition operation where a single event consists of acquiring data from each multiparameter I/O module simultaneously and transferring all the data through the first multiparameter I/O module in the chain. A single multiparameter group and multiple singles mode devices are allowed in each chain of I/O modules.
