Beschreibung

The Tektronix WA73A-455 Module is a direct replacement for the obsolete CDS / Tektronix 73A-455, and is a truly form, fit and function replacement for that unit. All software developed for use on the Tektronix 73A-455 may be run without modification on the WA73A-455. All interface connections to the front panel are identical pin-to-pin format, allowing the WA73A-455 to be used in place of the Tektronix 73A-455, without change to cabling. The WA73A-455 Module is a printed circuit board assembly for use in a card cage conforming to the VXIbus Specification. It allows the system controller in an ATE system to communicate with, and test devices that conform to the MIL-STD- 1553A/B data bus. The WA73A-455 Module consists of two identical VXIbus instruments in a singleslot VXIbus C-size package. Each of the two separate and independent channels, labeled A and B, has its own VXIbus logical address, its own interrupt, and a complete set of controls and indicators.

The WA73A-455 Modul offers three modes of operation for each channel:
•1553 Bus Controller (BC) Simulator
•1553 single or multiple Remote Terminal (RT) Simulator
•1553 Bus Monitor
