FAQ 2012-01-20

The Keysight 8761B SPDT Coaxial Switches are not listed in the "Keysight 34945A, L4445A and L4490A/L4491A Configuration Guide". Why?
Due to the 8761B’s internal design the RF path selection is achieved via DC polarity reversal across the coil control terminals. The Keysight 34945A, L4445A and L4490A/L4491A Control Units do not provide a polarity reversal mode. Thus the 8761B cannot be controlled by the 34945A, L4445A and L4490A/L4491A Control Units.
