8321 Multichannel Programmable Attenuator Systems

A Weinschel Product

API Weinschel's Model 8321 Series Multichannel Programmable Attenuator systems allow for multiple attenuator channels to be controlled across a variety of interfaces, or via a front panel.

The 8321 series are housed in full rack enclosures and can be configured for up to 16 attenuation channels.

This series can be configured for front, rear, or front to rear RF connections.

The 8321 series uses a message based, IEEE 488.2 compatable command set. Control software is included.
