Direct Reading Attenuator, 0.5-4.0 GHz
This series of variable attenuators is our most popular type for direct reading attenuators. As in most of our units, it features a non-contacting method of varying attenuation, and calibration does not change with usage.
GENERAL CHARACTERISTICS
Direct Reading Models are furnished with dials individually calibrated in 1 dB increments. These units are flat with frequency.
Level Set Models are supplied with dials in degrees for reference. These units do not have attenuation vs frequency specifications. All level set models can he directly calibrated at a spot frequency; contact factory.
Special Models: Most units are manufactured to customer specifications. Accuracies can he quoted for your exact attenuation range and frequency hand; contact factory.
