A broad range of laboratory grade programmable capacitance decade boxes for applications requiring a programmable impedance unit controlled manually and by a computer via an IEEE-488, RS-232 interface.
The PCS Series is a broad line of high precision programmable decade capacitors. They provide straight capacitance in a wide selection of ranges, tolerances and ratings. IET Labs also supplies custom combination substituters for capacitance and resistance as well as sources for voltage and current.
The PCS Series is a precision substituter with excellent characteristics of stability, temperature coefficient, and power coefficient. High dynamic ranges are available, starting as low as 1 pF and extending for as many as 10 decades. These features combined with a low virtually constant residual impedance make for very versatile instruments.
The PCS Series features two optional special settings, an “open circuit” and a “short circuit”. These modes are useful for obtaining reproducible transitions between settings, i.e. break-before-make or to short between settings. The “short circuit” setting also provides a reduced zero setting impedance.
