This is an old question that may have been resolved, this input is to help others that may have this inquiry. The ESA E4407B as well as all ESA family, has been discontinued. When an instrument is discontinued, options are also generally discontinue for specific models or family. Support generally last 5 years post obsolescence. However, there are still some universal options which are used across model families, that can still be obtained. Contacting your sales rep would be the ideal way to locate current options such as PathWave Software. (89600 VSA platform)
