content: As the second part of my instrument-purchase list, I'm looking for a cost-effective digital scope.I had CRT-based ones at my home (from Tek and others) but not anymore. I want to forget that time spending too much time at the buttons of the scope. I like very much the option of "auto-adjust" of the Agilent scope I use at work and I need something similar for my personal-home scope.Frequency is critical because I observed that certain signal details are only properly captured at scope freq. >3x the basic freq. of the signal.Therefore, for my research, 50-100MHz is my initial goal. I want to have the easy operation of saving the screen data directly into a USB stick.Finally, and OPTIONAL, I'd like to have the option of having a PC software (I can program it by myself if necessary or use LabView) that regularly take ssnapshots of the signals that are being captured by the scope.My initial choice is the RIGOL DS1102E for multiple reasons, in particular its low price and high performance.Can you give me comments that let me take a proper decision?Thanks a lot!!

content: You definately do not want the DS1102E. It is physically identical to the DS1052E which you can hack to become a DS1102E.I personally would not buy either one anymore, I would get a Rigol DS2072. The new 2k series totally blow out the 1k series out of the water. And the best part is that you can hack the DS2072 as well to have more bandwidth and have all the software options like bus decoders and what not.

content: Quote from: Dago on November 12, 2013, 09:11:57 amThe new 1000Z is a very good low cost option, not too far off the 2000, and 4 channels.Yes, the old 1052E/1102E now has a very narrow market space.

content: @EEVblog: Hi, I did not fond references for Rigol 1000Z. Is the model correct?@Dago: the problem is the cost of DS2072: ~3 times $DS1102E@Dago: the cost of DS1052E is pretty similar to DS1102E. Waht are the advantages of the former?

content: 1000Z refers to theDS1000Z series, which includes for example the DS1074Z 70 MHz model. There is no advantage to the DS1052E over the DS1102E except price. The DS1102E has the advantage of having a guaranteed 100 MHz bandwidth out of the box without hacking and possibly voiding the warranty.

content: If DS1052 and DS1102 are not the best options, what are the other options for a $400 scope?Is Siglent SDS1102CML a proper choice?

content: I recommend you to buy DS1052E and then hack to 100MHZ bandwidth, but first makesuer it can be hacked(the newer version may not be hacked),then it's function is the same as DS1102Elow cost and high performentsthe best chioce

content: I bought a 1052E a while back, it appears to be decent, but that was a while ago.Cough up the money for a DS1000Z series at all costs at minimum if you need to buy now, or a DS2000 series if you're absolutely sure you'll never want 4 channels.However, unless you need it right now, wait for the verdict on the MSO/SDS2000 from Siglent.

content: IMHO the Rigol DS1000Z series is very good value for money since it has 4 channels. I think I'll buy one to have at least a more portable scope to take to customers.
