--- Quote from: robca on May 18, 2020, 10:40:05 pm ---I might be able to buy a used DS2072A. Currently asking $600 for it, but has not been sold for a long time, so might be open to a lower offer. Considering the age, what would be a fair price for a DS2072A these days? I doubt I'll ever need more than 100MHz, so a DS1054Z (hacked to 100MHz) would work equally well and have 4 channels. But, then again, I rarely need more than 2 channels, and in cases where a lot of digital signals are needed, a logic probe works usually as well. So my main alternative would be a DS1054Z or an even cheaper used 2 channels Rigol I see that once hacked, the DS2072A maintains the features. Is there a version of the firmware that does not allow hacking anymore? I'm sure it's in the thread, but I haven't had time to read thru the 113 pages yet, sorry --- End quote --- I've had a few of the models in this range (1054Z, 1074Z, DS2072A, and MSO2072A). Given what you describe as your options (used and new) and your requirements/interests I'd say go for a new 1054Z (get a slight discount from tequipment.net and a warranty). It can't hurt to have the extra two channels (you might come up with some reasons to use more than 2). When I bought the 2000 series (and I'm still happy with the one I have) I was slightly smitten by the big Nav knob but I haven't used it nearly as much as I expected. It's still a great scope but it's hard to beat a new 1054Z in terms of price/features & performance. If you really want to spend more the next step up is probably a Siglent 1104X-E. Just depends on your budget and preferences. You could start with the 1054Z and sell it in 2-3 years for maybe half or more of what you paid for it and then look at what's the latest and greatest at that time, or your first scope might be all you need if you don't get TEA. |

I currently have a decent dual trace analog 100MHz scope, which works well for pretty much everything I need, but it's huge and takes up way too much space. That and a logic probe, and I can do pretty much everything. The main reason to get a DSO is the small footprint. And less so some of the memory features. But it's hard to justify ~$350 for just a smaller footprint (and, yes, i was aware of the eevblog discount, but thanks for mentioning it) That DS2072A used was tempting because I might be able to get it relatively cheap for the type of instrument and with the 300MHz bandwidth would at least offer a real upgrade over my analog one, in case I need more bandwidth in the future. What price would you consider a DS2072A to be a "too good to turn down"? Would paying close to a DS1054Z be a good price? |

It's a thinker. If I needed to replace my existing MSO2072A and I had to choose between a used 300 MHz DSO272A and a 1054Z for the same price, I guess I'd go with the 300 MHz DSO2072A. Really depends on how much I thought I was going to use/need want the extra bandwidth. It's kinda on the edge because as much as the bandwidth is attractive so are the four channels - especially for digital (SPI in particular) - although a lot of folks are very happy with a $10-15 eBay logic analyzer that runs Sikgrok PulseView. The LA won't let you see the analog and digital signals at the same tjme on the same screen, but that might not be important (depends on what you will be doing), and you can add the LA no matter what scope you go with. If I couldn't see some fairly specific use for the extra bandwidth then somewhere around a $50-$100 lower price plus new, plus a warranty I'd probably go for the 1054Z. Might depend on how pristine the 2072A is, does it come with the probes, or are their some issues known or TBD on the used scope. I like Rigol a lot but given what I hear you saying and asking about, I think you might be a candidate for a Siglent 1104X-E with a discount from Saelig. I'm pretty sure if I was buying now in this general range I'd go for the 1104X-E but it really comes down to how bad you want the bandwidth and in what package you want to get the bandwidth. Either way, you are going to enjoy a smaller footprint and the ability to digitally capture and manage signals. (It's great that you have the analog scope - you will never wonder again what you might be missing with ether analog or digital. Plus, it's nice having two of anything as a backup and to check the sanity of your measurements once in awhile when you have a head scratcher.) If you think this might be your last scope, then maybe the maximum bandwidth you can get is the driver. If you want to experience digital and see what you learn and need for your next scope, I'd go for the 1054Z or 1104X-E. It's possible that with any of the scopes you are considering plus your analog scope you will be all set. |

Plus 1 for the DS1054Z route; you can use Riglol to make it into a DS1104Z (it says so on the System Info) and real world -3dB bandwidth is in the 130 - 150 MHz area after applying the upgrade. |

Hi, I've been enjoying reading the threads here. what would it mean if my DS2072 refuses to upgrade firmware? it's at 00.01.00.00.03 hardware 1.0.1 In diagnostic mode i wait a moment with SINGLE illuminated, stick in the stick, and all the lights come up, no blinky CH1. tried all these different .GEL files. I'm following the usual guide as far as I know. https://www.eevblog.com/forum/testgear/first-impressions-and-review-of-the-rigol-ds2072-ds2000-series-dso/msg158684/#msg158684 connected it to ultrasigma last week. not cynical to think that'd be the cause is it?! Edit: I found this regarding formatting the USB stick correctly: https://www.eevblog.com/forum/testgear/rigol-ds1074z-not-recognising-usb-flash-drives/ I used Rufus. UPDATED. |
