L-3 DFC-104-1 Frequency Conditioner

The L-3 / Aydin PCU-800 Series I/II/III Programmable Conditioning Units provides signal conditioning and encoding for many types of sensors and transducers into a format suitable for recording, transmitting, or real-time analysis by computer-based systems. The PCU-800 Series is a modular system which accepts a number of plug-in cards, each of which can be used for a unique sensor or measurement type. These cards are fully interchangeable with each other and can be used in any desired combination depending on the measurement requirements. The PCU-800 Series is fully programmable, allowing the user to change key parameters on a daily basis if required. These parameters include channel scheduling, gain, offset, PCM format and synchronization, resolution, output coding, etc.

The L-3 / Aydin PCU-800 Series I Programmable Conditioning Unit provide the acquisition, encoding, and transmission of data in commercial, industrial, and military environments. The equipment housing is populated with plug-in cards which are selected and configured to meet exact requirements of a particular test, yet have the flexibility to be adapted to other test scenarios through field reprogramming or reconfiguration. The system is fully programmable via windows-based ADASWARE software.

The L-3 / Aydin PCU-800 Series II Programmable Conditioning Unit combines precision analog and digital signal conditioning and acquisition circuitry along with a 12-bit, high performance PCM Encoder. Data acquired by the system is conditioned, digitized, and encoded in accordance with IRIG-106 telemetry standards. Multiple, simultaneous outputs are provided to support RF telemetry, recording, or diagnostic requirements. The user has full software control of all system features including channel gain, offset, and sample rate. Some additional features are controlled via connector strapping and/or plug-in jumpers on the system's internal control panel. Aydin Vector's ADASWARE software allows a non-technical operator to control the system's operation. The software is hosted on the user's PC-based computer using the DOS environment. The PCU-800 Series II is derived from the PCU-800 Series I products. Enhancements include circular military interface connectors, greater field maintainability, and simplified access to user-selectable features. Applications include: aerospace vehicles, launch vehicles, and flight test vehicles where the convenience and added reliability of circular connectors is important.
