content: 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..

content: From Rigol website:The Rigol DS2072A is a multi-functional high performance digital oscilloscope. Standard features include - Sensitivity down to 500Î¼V/div, record, replay & analysis functions, selectable 50â„¦ 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.

content: 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.

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

content: Check the teardownThere's no sig gen output connectors and obviously no sig gen board.

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

content: Quote from: tec5c on October 27, 2015, 10:07:00 amOkay, so that means that it's most likely software-enabled.Which means that the DS2202 is the same as the DS2072And the DS2202 doesn't have a signal analyserTherefore, there is a difference in the hardware between the DS2072A and the DS2072A-S
