About the Instrument Recommended Accessories
Table 1-1. L4490A and L4491A Instrument Input Power Specifications.
The L4490A/L4491A should be operated in an indoor environment where
temperature and humidity are controlled. Condensation can pose a potential
shock hazard. Condensation can occur when the modules are moved from a cold
to a warm environment, or if the temperature and/or humidity of the environment
changes quickly.
Recommended Accessories
Switches and attenuators interface to the L4490A/L4491A through distribution
boards. The Y1150A - Y1155A distribution boards are ordered separately based
on the switches/attenuators used in your application. Similarly, recommended
cables are included with the Y1170A-Y1175A series of mounting bracket kits,
and are available individually in the Y1157A - Y1159A cable kits. Like the
distribution boards, the bracket kits and cable kits are ordered separately.
Table 1-2 lists some of the common Keysight switches/attenuators and the
distribution boards, bracket kits, and/or cable kits they require. Review Table 1-2
carefully to ensure that you have the appropriate accessories for your switches
and attenuators. This will save you time and frustration!
