The Agilent/Keysight 3750A is a precision attenuator and network parameter analyzer engineered for DC to 100 MHz applications. It provides stepped attenuation control from 0 to 99 dB in 1 dB increments via pushbutton switches, delivering stable performance across its full frequency range. Optimized for 75 Ohm systems, the instrument minimizes signal reflections and ensures signal integrity in component testing, system integration, and laboratory measurement environments.
Technical Specifications
• Frequency Range: DC to 100 MHz
• Attenuation: 0 to 99 dB, 1 dB steps
• Characteristic Impedance: 75 Ohms

– Key Features
• Precision pushbutton attenuation control in discrete 1 dB increments enables fast, repeatable signal adjustment
• 75 Ohm impedance matching across the specified frequency band minimizes reflections and maintains signal fidelity
• High return loss specification (28 dB minimum) indicates efficient power transfer and low VSWR
• Handles up to 250 mW input power, suitable for most signal conditioning and measurement circuits
• Flat frequency response from DC through 100 MHz supports both baseband and RF testing
– Typical Applications
• RF and microwave equipment calibration
• Component and subsystem testing
• Laboratory signal conditioning and level control
• System integration and verification
– Compatibility & Integration
Standard BNC connectors enable direct integration into 75 Ohm measurement systems and test setups. The attenuation range and impedance specification make the 3750A suitable for use in broadcast video, data communications, and general RF laboratory environments operating below 100 MHz.
