IET 1413 precision capacity decade
IET continues to produce the 1413 series capacity decadent to exactly the same specifications as GenRad. The GenRad IET 1413 precision capacity decade is a standard with a wide range of high quality and a reliable component for systems. It can be used as a tabletop model for versatile use or mounted in a system rack.
This six-capacity deccade features fine adjustment over a wide range of capacities, with excellent accuracy. Any value in the range from 0 to 1.111 11 uF can be set at a resolution of 1 pF, with an accuracy of 0.05% + 0.5pF.
For a wider range of up to 10,000 uF with comparable performance, the HASC-Z capacity decadence can be considered.
The GenRad 1413 uses air capacitors for the two lower decades. Mechanically stabilized sealed India Ruby mica capacitors are used for the rest.
Air trimmers are used for trimming the two lowest silver plated mica decades.
