- Why you need this attenuator - Precisely control RF signal levels to prevent receiver overload, reduce distortion, and enable repeatable measurements. - Ensure compatibility between test instruments and antennas or between different RF modules by matching signal strength. - Durable construction and predictable performance make it suitable for repeated lab and field use. - Key features and benefits - BNC male to female connectors for direct, tool-free connection to a wide range of RF devices and setups. - Durable stainless steel construction provides mechanical robustness for frequent handling. - Rated power: 2 W, impedance: 50 ohm — reliable performance for standard RF test and measurement environments. - Frequency range: DC to 3 GHz, supporting most wireless, RF, and microwave applications within that band. - Attenuation options from 1 dB to 40 dB, allowing fine control of signal levels. - Accuracy: +/-0.5 dB for 1–10 dB settings and +/-1 dB for 15–30 dB settings, giving predictable, repeatable attenuation for sensitive measurements. - How it solves common problems - Protects receivers and measurement equipment from high input levels by stepping down signals to safe, measurable ranges. - Improves measurement accuracy by reducing signal-induced compression and nonlinearity. - Simplifies system setup by providing a standardized 50 ohm interface and consistent attenuation values. - Compatibility and form factor - Works with any equipment using BNC connections and 50 ohm systems, including spectrum analyzers, signal generators, oscilloscopes with RF inputs, antennas, and RF amplifiers. - Conventional BNC form factor fits typical benchtop and field cabling arrangements without special adapters. - Typical use scenarios 1. Lab testing and calibration: Insert the attenuator between a signal generator and spectrum analyzer to set known signal levels for device characterization and repeatable measurements. 2. Protecting receivers in the field: Use ahead of a sensitive receiver or SDR when testing transmitters or strong signals to prevent input overload. 3. Antenna system tuning: Reduce signal strength from high-gain antennas to match downstream equipment and avoid non-linear behavior during setup and diagnostics. - Specifications summary - Connectors: BNC male to female - Material: stainless steel - Rated power: 2 W - Impedance: 50 ohm - Frequency: DC to 3 GHz - Attenuation range: 1 dB to 40 dB - Accuracy: +/-0.5 dB (1–10 dB); +/-1 dB (15–30 dB) Reliable, compact, and accurate — this BNC attenuator is designed to give predictable signal control for a wide range of RF test, measurement, and field applications.
