I'm not sure how to find out how old it is other than to look at the date codes on the main chips in the digital sections. I did this on mine many years ago and the youngest date codes I could find were from late 1986. The analyser was donated to the company some time around 1990/1 and I was the first to use it.

It didn't look new at the time so mine was probably made in 1987. I bought it from the company well over 15 years ago and for many years it was my main spectrum analyser here at home.

I'm not sure about Advantest serial numbers. It might be possible to decode the date from the serial number but I don't know how. I think the TR4172 dates back to 1981 but I'm not sure when Advantest stopped making them.
