Model 4000 Compact Telemetry System

4000
Combining proven hardware and software from Acroamatics and EMC, the Model 4000 Compact Telemetry system is capable of processing telemetry data streams with data rates of up to 32 Mbps. The Model 4000 is based on Acroamatics’ Model 1626P Frame Synchronizer and Model 472M Bit Synchronizer plus ILIAD Lite Telemetry Software from EMC Corporation. The Model 4000 enables the user to process PCM data using advanced software decommutation features and robust math-machine functions. Data is recorded in IRIG chapter 10 format and a utility is provided for the import/export of telemetry format information in TMATS, CSV and other file formats. An explorer-style interface guides the user through system setup effectively and data can be displayed in a variety of formats including a tabular “Tech View” and the advanced graphical “SL View”.

The Model 4000 is comprised of two components, a hardware front-end and software application. The hardware functions, including bit synchronization, decommutation IRIG time translation and PCM simulation, are performed in the Model 4000 chassis which contains the Acroamatics Telemetry Processor Hardware Suite capable of decommutating one IRIG 106 Chapter 4 or Chapter 8 telemetry stream. The IlIAD Lite Telemetry Software performs functions such as set up and control of the hardware, data display, data processing and data recording. The Model 4000 chassis is connected to the PC utilizing standard Ethernet protocol and connectivity. several PC’s and model 4000 units may be connected on the same network, thereby allowing independent work stations a selection of data sources as well as access for multiple hardware front ends.

Operational

Generate Mode
Time is generated from the onboard crystal oscillator and is presettable from the Host

Translate Carrier Mode
The internal timing is based on the input carrier. This mode enables the system to translate time as the input carrier rate varies during playback on an analog recording.
Translate Failsafe Mode
The internal timing is phase-locked to the input carrier. In the event of time dropout, the translator continues generating time without interrupt.
Frame Bypass
Automatic frame bypass compares previous time frame with current one, and Time Accumulator updated when they agree.
