2 Starting in June 2010, the current interrupt function (formerly Option
403) is a standard feature for these switches. The serial number
information below shows which switch units have the current interrupt
function included as standard.
N1810UL: Serial numbers MY07244672 and later
N1810TL: Serial numbers MY07247927 and later
N1811TL: Serial numbers MY07244660 and later
N1812UL: Serial numbers MY07240668 and later
3 Bracket kits apply to the L4490A and L4491A. These kits include
pre-assembled control cables and hardware for mounting switches/
attenuators to the brackets and the bracket assemblies to the L4490A
and L4491A RF Switch Platforms. Each bracket kit supports multiple
switches (Table 2). The Cable-only kits are primarily used with the
34945A and L4445A, but can also be used with the L4490A and L4491A.
These cables must be assembled and each kit contains material to
build multiple cables (Table 2).
4 Information on these attenuators plus additional information on
other attenuators can be found in the latest version of the ‘RF and
Microwave Test Accessories Catalog.’
