After a 1 month trial, SPS has gone ahead with purchasing a combined frequency response and wide bandwidth impedance analyser (PSM1735 + IAI fixture) manufactured by UK company Newton’s 4^th Limited. Having access to this piece of equipment will allow more accurate and reliable characterisation of the frequency response of the significant range of complex control systems that SPS develops.

The previous piece of equipment SPS used for this was limited in its ability and was reaching the end of its life. The Impedance Analysis Interface module will also assist SPS with assessing the performance of both standard and custom designed components all the way up to 35 MHz which is an essential part of switched-mode power conversion and Electromagnetic Compatibility development work.
