Variable/programmable attenuators
Attenuators -variable or stepwise- can be used to adjust the level of the power signal continuously or incrementally within a given frequency range.
They can also be used to adjust the power level of the test system, as insertion attenuators. It is small, high precision and high stability.
Programmable Attenuators are typically used to control the power level of microwave signals with a TTL\CMOS type control method and are designed for use in Automatic Test Equipment (ATE) systems operating in the continuous frequency range up to 18 GHz.
Characteristics :
- DC-18GHz, 2-300W, 0-127dB
- Wide choice of attenuation, frequency ranges and step sizes
- Stable attenuation accuracy
- High reliability and long life
- TTL\CMOS interface and driver circuits available
- Custom models available
