Advanced Power Designs introduces the Model
VXI150 Programmable PrecisionResistor Moddule. The VXI150 is a high accuracy programmable ladderpackaged on a single slot C-size VXIbus
card
The VXI150 provides any resistance value
between 0.5 ohms and 1.5M ohmsin 0.1 ohm increments
through the use of high power/high precision powerresistors.
The maximum current is 0.5 Amps and is power limited to 5W.
The VXI150 is designed
In addition to
these applications, many ATE designers find it much lesscostly
to use the VXI150 in place of fixed resistors which previouslyhad
to be housed in interface test adapters (fixtures). In many cases,the use of the VXI150 can lead to a reduction in the
number of uniquefixtures required and can reduce
fixture complexity and cost.
