Introduction
1.1 General Description
960SG Signal Generator is utilized to verify the proper operation of the Universal Digital Rate meter 942 Monitoring Systems and the Universal Digital Rate meter 956 Monitoring Systems. It simulates pulses from the radiation detector and is applied to the radiation pulse counting circuit. The 960SG can be supplied as part of a radiation monitoring system or as a separate, stand-alone piece of test equipment. The Model 960SG-500 is designed to mount in a 3-bay rack chassis. Figure 1-1 is the Signal Generator functional block diagram.
The Model 960SG-500 utilizes two independent 960SG boards in a UDR style housing, for UDR applications. Front panel controls include decade range, variable amplitude and variable frequency.
1.2 Application
The signal generator provides pulses to the UDR through the signal input jack. The user can select, via a slide switch, each decade in CPM from 0 CPM to 1 x 10 adjustment within the selected range.
