Distribution Boards
Each 34945EXT remote module can hold up to four distribution boards.
Distribution boards are designed to support the most common types of
Agilent microwave switches and attenuators. The table below shows the
distribution boards available and lists the supported switches and
attenuators.
Specific information for each distribution board and the supported switch
types is given in the following sections.
Distribution boards are specialized terminal boards and hold no active
electronic components. The distribution boards can be identified by the
system (refer to the
SYSTem:CTYPe:RMODule?
and
SYSTem:CDEScription:RMODule?
commands description in the
Programmers Reference Help file).
Channel drive attributes for each distribution board will be set to the
