If you require programmable decade box equipment in your Automated Test Equip
ment (ATE) design, our PZS Series should be your first choice. A broad range of laboratory grade decade substituters for applications requiring a cost effective programmable impedance unit controlled manually and by a computer.
Our HARS Series of Resistance Decade Boxes offer high stability and an accuracy of up to ±(0.01% + 2 mΩ).This decade box series is the best choice when you need a laboratory grade, tight tolerance, high performance resistance decade box that is also cost effective.
The HACS Series of Capacitance Decade Boxes offer high accuracy
of up to 0.05% and Excellent TC - as low as 20 ppm/°C. The HACS-Z provides a wide range of capacitance in increments as low as 1 pF and a total capacitance of up to 10,000 μF. With its high quality, tight tolerance capacitors, it is an ideal part of a test or calibration system.
The 1491 Series of Inductance Decade Boxes offer shielded toroidal cores for small mutual inductance and minimal effect from external fields and a high-Q (200
and above). The 1491 Decade Inductance Box is an assembly of several 940 Decade-Inductor Units in a single metal cabinet. The units have no electrical connection to the panel, but a separate ground terminal is provided, which can be connected to the adjacent low terminal, leading to the smallest decade.
IET also offers a full line of R-L-C standards, refer to our Standards Selection Guide.
