– Key Features
Thin-film attenuator cards employ high-stability tantalum nitride resistive film on sapphire or alumina substrates, ensuring precise attenuation control and minimal frequency-dependent variation. Large heat-dissipating fins maintain thermal stability under continuous maximum input power operation. Low insertion loss and high repeatability across measurement cycles support accurate signal conditioning in demanding test setups.
– Typical Applications
The 7563A is well-suited for RF and microwave test applications requiring fixed signal attenuation, power conditioning, and impedance matching in laboratory and production environments. Its wide bandwidth and power handling make it effective in both swept and CW measurement scenarios.
– Compatibility & Integration
The unit integrates into standard RF test systems and may be compatible with attenuator drivers and interconnect kits such as the Keysight 11713A or 11716 series, contingent on connector type and control interface alignment.
