Title: Rigol DS2072A vs DS2072A-S
Post by: mrpackethead on October 25, 2015, 07:38:31 am
Is there any difference in the hardware of the 2072A vs the 2072A-s Version... It seems there is, but I was'tn 100% certain..

From Rigol website:

The Rigol DS2072A is a multi-functional high performance digital oscilloscope. Standard features include - Sensitivity down to 500μV/div, record, replay & analysis functions, selectable 50Ω input impedance and 8" WVGA display with 256 grading levels. Furthermore, it possesses a variety of trigger functions, decoding functions, connectivity options, mathematical operations including FFT, automatic waveform measurement parameters with statistics, a pass / fail test and a built-in help system. A two channel 25MHz function / arbitrary waveform generator is included on '-S' models. The Rigol DS2072A is a versatile instrument that offers useful performance and features at a very competitive price.

I wonder if it's just a software-configurable feature...

like everything else in Rigol Land. One unit, with software features.

Does a 2072A have the output connectors on the back?

I've got the -s version. I don't think the standard version has the extra 2 BNC connectors on the back or the source button to the left of the jog dial.

Isn't the only difference being that the '-S' model has a built in sig. gen.? Hence, same hardware...

Check the teardown
https://www.youtube.com/watch?v=BWZXGzAVkD8 (https://www.youtube.com/watch?v=BWZXGzAVkD8)
There's no sig gen output connectors and obviously no sig gen board.

Not sure if there's any difference, but the one in the teardown is a DS2202 and not a DS2072...

It's only a bandwidth difference. 200meg vs 70meg

Okay, so that means that it's most likely software-enabled.
Which means that the DS2202 is the same as the DS2072
And the DS2202 doesn't have a signal analyser
Therefore, there is a difference in the hardware between the DS2072A and the DS2072A-S  :-+

DS2202 and DS2072 are hardware identical
DS2072A has 50om termination on inputs (small hardware change)

I think there's no software key to turn on signal gen or logic analyzer on DS2072A model, I think the firmware checks if hardware is present, and than uses it and shows additional menus.
