This unit
The Astronics/EADS/Racal 1260-35 is a high-density scanner/multiplexer module delivering flexible signal routing for aerospace, defense, and test applications. This C-size VXIbus module supports ten configurable multiplexer architectures ranging from 1×96 two-wire to 1×192 one-wire arrangements, optimize channel count against wire configuration. Each channel handles up to 1 A at 250 VDC or VAC rms, with 30 W DC or 62.5 VA AC maximum switchable power. Bandwidth reaches 50 MHz general operation, with >15 MHz (−3 dB) in 1×48 configuration. The module exhibits exceptional signal integrity: <600 pF open-channel capacitance, <0.1 dB insertion loss at 100 kHz (1×6 config), and 15 MHz (−3 dB) for 1×48 configuration
Open Channel Capacitance: <600 pF
Insertion Loss: <0.1 dB at 100 kHz (1×6 configuration)
Crosstalk: <−90 dB at 100 kHz
Power Supply: +5 V at 0.4 A (2.8 A with Option 01)
Cooling: 4.0 l/s airflow required
Key Features
Ten user-selectable multiplexer configurations optimize density versus wire count
Low thermal offset and exceptional crosstalk isolation (<−90 dB)
Relay coil current monitoring for closed-loop confidence checking
Dual control options: message-based (Option 01) or message/register hybrid (Option 01T)
Two connector variants: IDC ribbon or crimp pin user interfaces
Typical Applications
Aerospace and defense test benches
Multi-channel signal routing and scanning
Mixed-signal measurement systems
Automated test equipment (ATE) platforms
Compatibility & Integration Designed for VXIbus platforms. Requires adjacent smart card module (Option 01 or Option 01T) for control. Compatible with Racal Instruments legacy systems.

Astronics / EADS / Racal 1260-35 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Astronics / EADS / Racal 1260-35. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Astronics / EADS / Racal 1260-35 faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
