Description
Overview
The Keysight 8494G is a programmable step attenuator for RF and microwave applications from DC to 4 GHz. Unlike manual attenuators, it offers electronic control with fast switching time, making it ideal for automated testing, system integration, and high-speed measurement applications where signal control needs to be computer-controlled.
Key Features
- Frequency range: DC to 4 GHz
- Attenuation: 0 to 11 dB in 1 dB steps
- Programmable control with fast switching time: 20 ms maximum (including contact settling)
- High repeatability: 0.01 dB typical
- Insertion loss at 0 dB: 0.6 dB + 0.09 dB/GHz
- Maximum SWR: 1.5
- Maximum RF input power: 1 W average, 100 W peak
- Long operational life: 5 million cycles per section
- Optional NIST-traceable calibration data available (Option UK6)
- Can be cascaded with interconnect kits for extended range
Applications
- Automated RF and microwave testing systems
- Receiver and transmitter characterization
- Gain and loss measurement in test equipment
- Signal conditioning for automated measurement
