A stable, near reflection-less load is a key component in any Semiconductor or ISM industry test setup seeking to characterize a device or system with the greatest possible repeatability and accuracy.  The new 9700 S Series water loads have been specifically designed to address these goals with a guaranteed Max VSWR of ≤1.05 and upper frequency response of 100 MHz to give customers the assurance they can rely on the lowest reflection loads possible to meet their test system requirements.  By utilizing Power Film System’s* low TCR proprietary resistors along with Altronic’s water-cooled load designs, these loads provide superior results.  The 9700 S Series is available in power ratings of 5kW, 15kW, 25kW and 50kW.
