This unit
The Curtiss-Wright/DY-4 SCP-122 is a 3U CompactPCI single board computer built on the IBM PowerPC 750FX processor running at 800 MHz with 1856 DMIPS performance. Engineered for space and power-constrained rugged environments, it delivers balanced processing capability with minimal power draw. The SCP-122 is offered in System Controller (SCP) convection-cooled and Dependent Controller (DCP) conduction-cooled configurations across ruggedization levels L0 through L200.

Curtiss-Wright / DY-4 SCP-122 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Curtiss-Wright / DY-4 SCP-122. 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 Curtiss-Wright / DY-4 SCP-122 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.
Curtiss-Wright / DY-4 SCP-122 price
This Curtiss-Wright / DY-4 SCP-122 is listed at $1,650. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
Curtiss-Wright / DY-4 SCP-122 calibration cost
NIST-traceable calibration for the Curtiss-Wright / DY-4 SCP-122 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 →
