Telemetry Data Processing & Display

Model 4022 High Performance Compact Portable Telemetry System
4022 with path
Acroamatics’ Model 4022 Compact Telemetry system is a remarkably size and cost effective single stream PCM storage and processing solution, capable of ingesting serial PCM with or without synchronous clock in any IRIG approved PCM code format. The Model 4022 enables users to process and record PCM data using powerful native “real-time” card level embedded Frame Sync/Decom processors. Flecible, card-level “soft decom” processing techniwues are optimized for “quick-look” flight-line, instrumentation lab, and range recording, processing, data display and networked data analysis. The Model 4022 may be ordered configured in its base Frame Sync/Decom/IRIG Time/PCM Simulation configuration, or with standard options such as internal 474DM advanced Digital Bit Sync Ch 5 CVSD voice, and integrated high performance multi-band Quasonix receiver supporting ARTM Tier ), Tier 1 and Tier 2 demodulation technology.

The Model 4022 chassis is very compact and portable, allowing transport with a laptop in a standard briefcase/tote. The Model 4022 is easily interfaced to any standard Win 7 or XP laptop or desktop, or can be operated directly using a standard local keyboard and monitor. Included Acroamatics CTS software suite (ATSS) supports bit sync and decom set-up, time correlated data recording, Ethernet “Gateway” PCM data delivery, output to third party processing applications, post test analysis/playback (including serial PCM playback and simulations), native data frame display, and more.

When used in conjunction with provided Acroamatics Telemetry Software, the 4022 CTS delivers a seamless high performance single stream, telemetry ground station decom processing, display, and recording solution – with support for TMATS set-up and Chapter 10 data exchange. Optional ILIAD-LITE software is also available with the Model 4022 CTS for flight test instrumentation engineering specific applications.

Program selectable. Front Panel NRZ-L Data and 0° Clock and internal bit sync decom inputs standard (with bit sync option). To five program selectable decom inputs supportable on an optional basis.
Subframe Sync
Six independent synchronizers are capable of decommutating subframes within subframes. Subframes synchronize to fixed recycle patterns, complement frame sync patterns, and various ID patterns. Both recycle and ID patterns may be assembled from multiple word locations. Recycle patterns may be up to 32 bits long.
ID Sync
Two types of ID synchronization are supported: JAM patterns of arbitrary values, and incrementing or decrementing frame counters with limit checking. IS sync words may be up to 16 bits in length.
Sync Strategy
Programmable Search-Check-Lock sync strategy, bit error tolerance, and bit slip window provide reliable frame synchronization.
Asynchronous Formats
Subframe synchronizer may be programmed to decommutate embedded formats having unique frame sync patterns and format structures.
Format Switching
16 testable flags store the results of select input stream bit and word comparisons to control 4022 CTS PCI card level real-time user input format switching. Frame Sync/Decom format switching is loss-less and immediate. Multiple card resident micro-coded decom processing programs are stored in local decom memory in support of such conditional format switching events.


Standalone Data Output
Data is processed in specialized card resident real-time processors, independent of any Windows (or similar) operating system. Processing latency is minimal, and related solely to access to rate parameter data. Decommutated data are available to the system internal PCI bus as memory-mapped frame buffers. Current value Table (CVT), or as a data stream selectively transferred by PCI bus DMA. Data is 32 bits with programmable MSB/LSB output word justification, sign extension, or zero insertion for LSB output. Acroamatics Telemetry System Software (ATSS) suite provides a complete suite of GUI Windows compatible system set-up and operating programs in support of user decom and mission system data management, data display, alarming, limit setting, recording, analog and networked data I/O processes and local operator status display, and networked remote system management and data operations.
Frame Quality
Frame quality is word generated containing bit sync and frame sync status for downstream data validation.
2 Serial PCM Outputs
Two program controlled RS-422 compatible serial output channels are supported.
Sim-encoded Data Mode
The Model 4022 CTS supports transparent playback of recorded PCM stream data directly from disk. Output is via the system front panel PCM SIMULATOR OUT output jack (single ended, unless Optional RS-422 Sim output is specified) and is both code and output data rate selectable (see PCM Simulator section for additional details).
CVSD Audio (option)
Optional IRIG Ch 5 CVSD or PCM encoded digital audio format decommutated audio output is available. CVSD processing is in real-time, maintaining extremely low system latency. Voice output is delivered directly from Model 4022 CTS card level real-time processor DAC outputs, and is user programmable as to output gain, format and sampling characteristics.
