RF and Microwave Switching
A variety of RF and microwave switch modules are also available for the
34980A. This includes RF multiplexers (34941A, 34942A), SPDT switching
from dc to 20 GHz (34946A, 34947A), and a switch/attenuator driver
module (34945A) that allows you to control switches or attenuators
external to the 34980A mainframe.
For more information, see “Introduction to the Plug- In Modules for the
34980A” on page 163.
CAUTION
The 34946A and 34947A support only 24 VDC coil options for the
N1810 switches. If the proper voltage option (Opt. 124) is not used,
the switches could be damaged. N1810 switches also require option
201 “D” subminiature connectors and option 402 Position
Indicators.
