MICHAEL LOHRER is right on the money about Programmed Test Sources and their synthesizers ("Survey Omission," Feedback, May 2007, p. 13). We love them here at CEC and use them as essential components of many of our transmitters. They're about the most reliable units we've seen over the years. And we've never had a case where a PTS unit didn't live up to its specifications. The phase noise is always within specifications as is the accuracy. Another great thing about PTS is that they deliver on time. And if we need a legacy function, they provide us with it. PTS is just a wonderful, reliable source whose products are both economical and dependable. I recommend them, I can rely on them, and I use them.
