8320 Multi-channel Programmable Attenuator Systems
A Weinschel Product
Spectrum Control's Weinschel brand Model 8320 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 8320 series are housed in half rack enclosures and can be configured for up to 4 attenuation channels.
This series can be configured for front, rear, or front to rear RF connections.
The 8320 series uses a message based, IEEE 488.2 compatable, command set. Control software is included.
