iPIMMS in Penang

About this Article
This article by Gayatri Choudhury and Ian Instone explains how and why Agilent's standards lab in Penang is using a network analyzer that is linked via the internet to the British national metrology institute.

Abstract

Measurements made using Vector Network Analysers are as complex as they are fascinating. The internet-enabled Primary Impedance Measurement System (iPIMMS), which was launched in 2001 by the National Physical Laboratory (NPL) in the United Kingdom, allows microwave network analyser users to achieve uncertainties which are equivalent to those of measurements performed at NPL.

The iPIMMS development took into account many key preferences for any calibration laboratory; namely traceability to National Standards, a very short traceability chain, low uncertainties and reduced cost of calibration. These aspects easily justified the need for an iPIMMS at Agilent’s largest manufacturing site; in Penang, Malaysia.
