Post by thread:[EE]: Which DSO to choose !

Javier, IMHO, any scope is better than none at all. But realsitically, all the scopes you mention are worthy of consideration. My best advice is get the one with the most that you can afford. The first criteria I would look at is what I plan on using the scope for, and what bandwidth I would need for that use. And here, generally more is better. The second thing I would look for is features. Such as memory depth and the ability to add more memory in the future if possible. Triggered sweep on more than on channel (rather common today). Sweep magnification to get a better look at glitches, etc. The next thing I would look at is extras. Such as do probes come with the unit, or do I have to buy them seperately. Communication cable for connecting and controlling the unit from a computer to enable simple ATE setups, etc. The forth thing I would look at is price versus the criteria mentioned above. You should look at all the things that are important to you, study the specs of the different scopes you are looking at, and then weigh the importance of each of the criteria you decide to look at, and then choose the one that best fits your criteria. It takes some time to go over the criteria and decide, but if you do it this way, you'll be able to get many years of service out of your scope before you outgrow it, or it needs to be replaced. Anyway, that's my take on the subject, and my opinions on how to decide which is best for you. One last thing, if you have unlimited funding, things get significantly easier. Hope this helps.

I have a tek tds210, and it's great. Sits atop the desk in a spot that isn't nearly big enough for a "regular" scope, and throws into a closet if I need it even further out of the way. I haven't used it a lot yet (thus the inability to justify a tds220, even to myself), but so far it's done everything I've wanted it to do. Nice automatic measurement features, too.

Hi Javier, I bought an HP 54622D (DSO) last year and it has REALLY worked out well for me. It has 2 channels of analog (100 MHz) and 16 channels of digital, can trigger on I2C, as well as other methods, is fairly small, has a floppy or can connect to a PC for remote control, etc. Great for PIC work. The horizontal can go down to 5 nS/cm but even at higher values has a REALLY wide buffer so you can really expand the signal nicely. I first saw the scope at a MicroChip conference here in Silicon Valley and, after drooling over it for a couple of months, decided to buy it. They also have lower speed (60 MHz) versions available with and without the digital (logic analyzer) section. I really like having both pieces in one package.

I would like to enthusiastically second the recommendation of this scope. The 16 digital channels to go with the 2 analog channels increases the usefulness tremendously (and I've never used all 16 channels - just being able to show 4 or so digital signals along with the a/d inputs is extremely useful). Plus the ability to trigger on i2c has already also proven useful. I don't know what the scopes originally mentioned cost - we paid approx. $4500 for the 54622D. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

I don't know if to buy it refurbished or new, the price difference is $400, any hints? I don't know. What would be the HP replacement for the TDS210 (DSO 60Mhz 1G sampling, 2channels)?? Unless I misunderstand things, the TDS210 is NOT a DSO (Digital Storage Oscilliscope.) It's a Digital REAL TIME Oscilliscope. Not having used a real DSO, I'm not quite sure what all the differences are. The TEK will catch a single one-time waveform, though, which is nice and one of the big things a DSO will do (I thought), but I don't think it has nearly as much memory or as many options for looking at memory as a real DSO. (I'm not sure it has any memory at all in the DSO sense. What it has is memory in the DISPLAY, I think.) BillW -- http://www.piclist.com hint: The PICList is archived three different ways.

Hi I treated my self to a TDS210. They are excellent scopes for the money. Very compact. All the controls and set-up are pretty easy and as easy as any other scope I've used (easier than some). Display is nice. I have not had any problems with it at all. I recently added the expansion module this is ok for taking captures to the PC or direct to the printer but I have not used this very often. The biggest criteria is budget!. For the home hobbyist the TDS210 is usually the first reachable price bracket. If affordable, some higher end DSO's are worth going for, The TDS210 has only the basic's (for DSO's that is). Its worth finding people / distributors who may have some of the DSO's as demo's, get and play with them you'll get an idea of how they interface with the user (you). For > £800 I should think rep's are willing to demo the products. Best of luck.

My boss bought me a THS720A. This is a great portable general purpose scope. It's LCD display, got good triggering options and dual isolated input channels, so no worries about grounding or shorting signal sources. It's easy to use, and battery powered. Also, it's small on my bench. I don't know about you guys, but sometimes I could misplace a Volkswagon on my bench....
