1 Platform Migration 8510 to PNA Graham Payne Application Engineer Agilent Technologies

2 We set the standard When we introduced the 8510, we changed the way S-parameter measurements were made!

3 and today, we raised the standard! 2000 to 2003 By introducing the PNA Series, we are changing the way people view network analysis (because it is more than just S-parameters!)

4 Why is Agilent discontinuing the 8510? PNA sales have replaced the majority of 8510 sales New PNA solutions are focused on replacing remaining 8510 applications (mmw, antenna and pulse) 8510 is 20 yrs old: 8510 sources are being discontinued obsolete parts require continual re-design lower sales volume = higher costs & lower profitability
