This unit
The IFR Aeroflex DF-7708 is a test interface matrix that bridges test systems and ARINC 708 weather radar units under test. It manages all non-RF interfaces - power distribution, discrete signal control, analog voltage sourcing, and data bus routing - according to ARINC-708 specifications. The unit integrates with WRX and WRC-7708 weather radar test systems and operates under control of a 24-line by 80-character CRT monitor and hex keypad, presenting all functions in ARINC-708 terminology.
Technical Specifications
- Four programmable ARINC-708 control bus outputs with independent data and transmission rate control
- Two attitude bus outputs (onside and offside) with independent programmable parameters
- Three ARINC-708 data bus outputs with four selectable patterns: X/Y crosshatch, bar, arc, and sector
- Six programmable high-speed and low-speed I/O buses
- Low Speed Bit Rate: 12.6 kHz
- High Speed Bit Rate: 100 kHz
- Data Bus Bit Rate: 1 MHz
- Control and data bus message transmission rate: 0 to 255 messages per second in 1 message per second increments
- Selected display capability for one of four input control buses and one of three input data buses
Key Features
- Sources analog three-wire and two-wire voltages to the unit under test
- Sources Johnson Code drive for Collins Antenna Pedestal
- Routes ARINC control buses, digital attitude buses, and data buses to appropriate UUT connector pins
- Controls and monitors all discrete signals per ARINC-708 specification
- Controls and monitors UUT power distribution
- Front panel test points for signal monitoring on all UUT connector pins
- Unique interface cables provided for each UUT type
Typical Applications Weather radar system development, integration testing, and production validation in aviation platforms requiring ARINC 708 compliance.
Compatibility & Integration Designed for use with WRX and WRC-7708 weather radar test systems. Compatible with Rockwell Collins weather radar systems when used with the STD-7000A digital controller and RDX-7708R/RDX-7708BRW equipment.
IFR Aeroflex DF-7708 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the IFR Aeroflex DF-7708. Calibration covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common IFR Aeroflex DF-7708 faults: power supply failure (cRIO-9073/9074), C-series slot connector wear, PXI chassis fan failure, GPIB interface failure on VXI controllers, BIOS/EEPROM corruption. NI CompactRIO most common faults are power supply failure on older cRIO-9073/9074 chassis and C-series module slot connector wear from repeated hot-swap cycles. PXI chassis fan failure is the most common wear item — chassis fans are field-replaceable. VXI embedded controllers most commonly develop EEPROM corruption and GPIB interface failure.

IFR Aeroflex DF-7708 calibration cost
NIST-traceable calibration for the IFR Aeroflex DF-7708 is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers analog input channel accuracy and offset at all gain settings, analog output accuracy, digital I/O logic threshold verification, sample rate and timing accuracy, and trigger and synchronization bus functional verification. NI CompactRIO and PXI chassis also undergo backplane trigger line integrity check.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
