The AXN/ENC/401 is used to encode data in an IRIG-106 Chapter 4 (Ch.4) PCM stream - up to 10 PCM codes at up to 40 Mbps.
Features
- Sixth order linear phase (Bessel) PMF with programmable cutoff from 175 kHz to 6 MHz and output voltage from ±0.5 Vp to ±2 Vp
- Up to 10 PCM codes at up to 40 Mbps
- 2 to 250K words per minor frame
- 1 to 64 bits and parity (odd/even/none) programmable word by word
The Axon Quick Start Kit consists of fully qualified, released hardware and software and can be expanded as future Axon modules become available.
The AXN/ADC/401 is used to condition and digitize up to eight analog channels.
The AXN/EXT/401 is an extender card, which allows modules contained in an Axonite (AXN/ITE/01U) remote housing to connect to an Axon chassis.
The AXN/ITE/01U allows Axon user modules to be housed remotely from the Axon chassis.
The AXN/CHS/09U is a compact nine user-slot data acquisition chassis, which includes a housing and backplane.
The AXN/CHS/16U is a compact sixteen user-slot data acquisition chassis, which includes a housing and backplane.
AXN/ENC/401 Axon IRIG-106 PCM Encoder
The AXN/ENC/401 is used to encode data in an IRIG-106 Chapter 4 (Ch.4) PCM stream.
In Ch.4 mode, parameters from any Axon module in the chassis can be placed in the Ch.4 PCM stream. Parameters from other Axon chassis and Ethernet sources can also be placed in the Ch.4 PCM stream.
Ethernet frames are input to the Axon chassis via the controller and passed to the AXN/ENC/401 across the backplane.
Multiple AXN/ENC/401 modules can be included in an Axon system and parameters can be sent to some or all encoders. The AXN/ENC/401 has differential-ended RS-422 outputs for data and clock along with buffered TTL outputs for NRZ-L, DATA, DCLK, word, minor-frame, and major-frame pulses.
The AXN/ENC/401 also has a programmable premodulation filtered analog output, which is suitable for use with a linear FM transmitter for telemetry. The cutoff frequency and amplitude can be changed to suit the bit-rate and transmitters' deviation sensitivity.
All physical outputs transmit the same payload data using independent line encoding (PCM codes) configurations.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
