34905A/6A Dual 4-Channel RF Multiplexers
These modules consist of two independent 4-to-1 multiplexers.
The channels in each bank are organized in a “tree” structure to provide
high isolation and low VSWR. Both banks have a common earth ground.
This module does not connect to the internal DMM. You can connect
your signals directly to the on-board SMB connectors or to the
SMB-to-BNC cables provided with the module.
NOTES:
• The 34905A is used for 50Ω applications. The 34906A is used for 75Ω applications.
• You can close only one channel per bank at a time on these modules; closing one channel
in a bank will open the previously closed channel. One channel in each bank is always
connected to COM.
• This module responds only to the CLOSE command (OPEN does not apply). To OPEN a
channel, send the CLOSE command to another channel in the same bank.
