BR121 series attenuator
BR121 series attenuator
Product Description
The BR121 series is an attenuator with a 121dB high power attenuation range, a step size of 1dB, and an adjustable attenuation value. The BR121 series attenuators have a digital keypad design. The PC serial port control provides simplicity and selectivity for the test method. Excellent attenuation status standing wave, with good attenuation accuracy in large temperature range and full dynamic range. It has a wide range of applications in various precision test equipments, electronic analyzers and communication systems. Among them, BR121 is a single-channel program-controlled attenuator, BR121-C program-controlled attenuator is four-channel, BR121-B program-controlled attenuator is a dual-channel attenuator, the attenuation process is cleared and not clear state.
