The VXI Technology SM8102 is a single-slot VXIbus dual-channel variable attenuator engineered for high-performance signal control in modular test systems. Part of the SMIP II family, it delivers precise attenuation with 0.05 dB minimum resolution across a range exceeding 60 dB, supported by low insertion loss and excellent return loss characteristics. The module accepts fiber optic signals via 50/125 µm, 3 mm loose tube cabling, making it suitable for optical and RF measurement applications requiring dynamic signal management.

– Typical Applications
Variable attenuation control in VXIbus test systems where precise signal level management and fiber optic compatibility are required. Ideal for measurement setups demanding dynamic range adjustment with minimal signal degradation.
– Compatibility & Integration
Interchangeable within the SMIP II series. Installs into VXIbus mainframes alongside other SMIP II products. Note: SM8000 series fiber modules cannot occupy the same base unit with standard SMIP II products, though different switch modules can be intermixed within SMIP II base units.
