5 Using Load Cards and Loads
Load Card Capabilities
• The Agilent E6175A 8-Channel High Current Load Card, with
integral current sensing, is intended to be used with loads
mounted on the card. A 9-inch by 4-inch area of sheet metal
is open on the front of the card for mounting loads. The card
is two slots wide to allow mounting of larger loads.
• The Agilent E6176A 16-Channel High Current Load Card is a
single-slot design, requiring externally mounted loads. This
load card offers high load density for high current loads
where current transducers and bridge drive configuration
are not required.
• The Agilent E6177A 24-Channel Medium Current Load Card
(for non-inductive loads) is intended to be used with loads
mounted on the card. A 9-inch by 4-inch area of sheet metal
is open on the front of the card for mounting small loads.
This card is one slot wide and capable of up to 2A continuous
carry current.
