If I had to take a bet, I would say the SR620 will be supported longer. Stanford Research seem to be selling the same products they have for decades. I started my Ph.D. in about 1994, and bought what was a very new product - the SR830 lock in amplifier. http://www.thinksrs.com/products/SR810830.htm 23 years later, it is still a current product. Stanford Research also sell a couple of LCR meters http://www.thinksrs.com/products/SR715720.htm The SR720 looks remarkably like the long obsolete HP E4925A LCR meter. There's no doubt in my mind that Stanford Research sell their products much longer than HP/Agilent/Keysight. Of course, that does mean Stanford Research are using older technology. I would add, when I have contacted Keysight about obsolete products they have always been helpful. When I contacted Stanford Research to ask what was the latest firmware for an SR620, I was ignored. They also ignored some other email I sent them. So their support does not seem as good as Keysight, but I assume, with persistence, one could get support on a current product.
