Overview

The Programmable PCM Simulator (FSIM) generates complex formats with asynchronous or embedded sub-frames at data rates from 1 Hz to 20 MHz. It has two 16-bit binary counters, two external words, a 16-bit program counter, and two 4k by 16-bit RAM memories. The FSIM has 1024 static and eight dynamic data words that can be used anywhere in the frame format. The FSIM generates all standard and randomized codes. This card is a stand-alone device and can be installed in any VME system as a PCM or PAM data simulator. All Acroamatics documentation is supplied on CD-ROM.

System Software

GUI Setup and Operation Status for the 1502V is controlled via a single interface with drop down menus.
