8321 Multi-channel Programmable Attenuator Systems
A Weinschel Product
Spectrum Control's Weinschel brand Model 8321 Series Multi-channel 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 compatible command set. Control software is included.
