官网介绍

2186 & 2187 Microwave Attenuator：Wide Range GPIB programmable attenuator with outstanding accuracy for bench top, automatic and standards applications.

• Attenuation from 3 to 130 dB
• 1 dB steps
• DC to 20 GHz frequency range (2187)
• IEEE-488.2 interface fitted as standard
• External relay driving capability
• Calibration data to international standards
• User calibration facility

The 2186 and 2187 are microwave attenuators covering the frequency range DC to 5 GHz (2186) and DC to 20 GHz (2187) with an
attenuation range of 3 to 130 dB in 1 dB steps.

Microprocessor control provides simple and rapid operation either by direct keyboard operation or via the IEEE-488.2 interface which is fitted as standard.

The 2186 and 2187 are ideally suited to ATE applications with rear panel input and output versions available as options.
