The APCM-404A is used to encode data in an IRIG-106 Chapter 4 (Ch.4) PCM stream.
Key Features
- IRIG-106 Chapter 4 PCM
- Dual RS-422 outputs up to 40 Mbps; 10 PCM codes; separate PCM codes per output
- NRZL TTL output up to 16 Mbps
- PMF output up to 8 Mbps
- PCM encoding of any system parameter without the need for separate Ethernet bus monitor
Applications
- RF transmission of PCM IRIG-106 Ch.4 streams
The ADAU-2009 is a 9 user-slot Axon chassis, which along with the housing and backplane, includes an isolated 100W power supply for the controller and user modules.
The AFED-424A monitors the status (high/low) of up to 24 differential-ended discrete input channels.
The ASCD-424A is used to condition and digitize up to 24 analog differential-ended channels. Single-ended configurations are possible by enabling programmable pull-down resistors on any of the negative inputs.
The ABIM-553A is a MIL-STD-1553 bus monitor, which can monitor up to four dual redundant busses.
APCM-404A-1 IRIG-106 PCM Encoder (PMF Output)
The APCM-404A is used to encode data in an IRIG-106 Chapter 4 (Ch.4) PCM stream.
Parameters from any ADAU module in the chassis can be placed in the Ch.4 PCM stream. Parameters from other system chassis or Ethernet sources can also be placed in the Ch.4 PCM stream.
Ethernet frames are input to the ADAU chassis via the controller and passed to the APCM-404A across the backplane.
Multiple APCM-404A modules can be included in an ADAU system and parameters can be sent to some or all encoders. The APCM-404A 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 APCM-404A also has a programmable premodulation filtered analog output, which is suitable for use with a linear FM transmitter for telemetry. The cut-off 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.
