This unit
The DDC SCS3740 is a high-speed, SWaP-optimized 3U SpaceVPX single board computer delivering performance in a compact, power-efficient package. Built around the rad-hard GR740 LEON 4FT quad-core processor, it achieves 1700 DMIPS and 90 Linpack MFLOPS while consuming just 5 W typical power. The SCS3740 integrates 128 MB EDAC-corrected SDRAM, 32 GB BCH-corrected NAND Flash, and 4 MB EDAC-corrected EEPROM, eliminating component count and enabling the first off-the-shelf quad-core LEON 4FT 3U SpaceVPX offering.

DDC SCS3740 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the DDC SCS3740. 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 DDC SCS3740 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.

This DDC SCS3740 is listed at $18,500. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
DDC SCS3740 calibration cost
NIST-traceable calibration for the DDC SCS3740 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 →
