ANAL0G T0 DIGITAL CONVERTER ASSEMBLY 2A2A13
(1) The analog to digital converter assembly 2A2A13 consists of Analogic ANDS
5400 chassis (model 5400), control I/0 CCA section, input CCA section, and two
drawer slide assemblies.
Both the control I/0 CCA section and input CCA section
contain electrostatic discharge sensitive CCAs.
(a) The Analogic ANDS 5400 chassis front control panel contains 14 push
and release switches and two LED information panels. The rear panel contains four
connectors (J19 and J20 - CONTROL IN/OUT, J28 - TRIGGER, J29 - 115 vat), a fuse, and
access to CCAs installed at the rear of the chassis.
A top cover, when removed,
allows access to a control I/0 CCA section,
+15 and +5 vdc power supply, and system
altered internal (ribbon type) W2 cable assembly. Two of its connectors (J19 and
J20) are hardware mounted to the rear panel.
The connectors on the other end of the
cable assembly connect to the CCAs in the control I/0 CCA section.
(b) The control I/0 CCA section uses five CCA card cage slot numbers 73
thru 77; slot 73 - ANA signal processor (model AC 262), slot 74 - A/D converter
(model 8016-20), and slots 75 thru 77 - three computer interface assembly CCAs.
(c) The input and simultaneous sample hold (SSH) section uses eight CCA
card cage slots numbered J1, J4 thru J8, J17, and J18. The following CCAs apply:
slot J1 - sample and hold (model AC 280), slots J5 and J6 - mux bus (model AC 4060),
slots J4, J7, and J8 - (hi-level) mux (model AC 4720), slot J17 - expansion
(model AC 333-1), and slot J18 - expansion (model AC 333-2). Input connectors P1
through P4 and P6 of system altered 2A2W1 cable assembly connects to the rear panel
(2) The analog to digital converter is a precision data acquisition/
distribution device that can process analog signals into digital data and digital
data into analog signals.
