Page 4: Introduction
1. Introduction The 578 4/8-Input MCS Module performs concurrent multichannel scaling from one to eight inputs when used in conjunction with a Multichannel Analyzer (MCA) System. The module uses the MCA PHA mode of operation with all data transactions between the module and the MCA occurring via the MCA’s ADC port using standard ADC signal arrangements and... -

Page 10: Input/Gate Connector
3.5 Input/Gate Connector Eight of the front panel’s connectors, labeled INPUT 1-8, are MCS count inputs, as shown in Figure 2.1. Depending on how the MODE switch is set, the four connectors on the right side of the front panel, labeled GATE 1-4, can be used as Gate Signal inputs. The input signal requirements for the Count and Gate functions are defined by internal switches. -

Time. The signal is high during sweep time and low between sweeps. At the end of the sweep, the 578 MCS adds one count per sweep to the first channel of each selected sub-group of the MCA as a sweep counter. Where supported, the acquisition system can use this for sweep termination by selecting one of these channels for a preset totals region. -
