The 1 GS/s Real Time Sampling Rate of Instek GDS-2102 DSO

[max0412]

I am purchasing a DSO I found this Instek GDS-2102.

http://www.signaltestinc.com/ProductDetails.asp?ProductCode=GDS-2102

Which seems very comparable to TEKS TDS2012B (Only $300 cheaper).

What I find odd is that I also found this (DSO Comparison chart)

http://www.wittig-technologies.com/english/start_engl.htm

Which states that GDS-2102 which claims a 1 GS/s Real Time Sampling Rate, has only a 100MSa/s per channel; on a two channel scope this equates to only 200MSa/s. How can they claim the 1 GS/s Real Time Sampling Rate?

If someone could enlighten me I would appreciate it. I already tried there techs as well as the manufacturers web site. Either no answer or they couldn’t explain it. Read the manual online still no explanation.

DSO Question

I received an email from Instek saying

"The information on your link is wrong. GDS-2102 has real time sampling rate 500 MS/s per channel."

With interleaving this results in 1GSa/s.

So the question has been answered. I post it here for anyone else looking for a scope.
