$320 DSO. 100Ms/s

[Sceadwian]

Software doesn't matter if the capture buffer is too small. If it's only 1k at the full sampling rate of 100mhz you're only going to have a capture window of 10 micro seconds. If the capture buffer is 32k or so it might be useable, but I somehow doubt it, they have another scope on the site that advertises 32k sample buffer per channel but it's 80mhz and is 420 dollars so I'm gonna hazzard a guess the capture buffer is pretty tiny, especially if it's not listed.

Maybe a design flaw and they are unloading this. But it says it is a sale.

I will email them for the buffer size, but I am starting to think I will pass on it. And I have an portable analog DSO. Just thought I could take it to work a lot easier.

What do you suppose this means? (see area highlighted in yellow)

 

[Sceadwian]

Means absolutely nothing as far as the DSO's features go.
It's the PC's software limit for storage of received information.
Every cell in my being says don't buy this thing =) Especially for 300+ bucks. You can get better for less used.

I'll agree there. The advertisements/website/etc look rather poorly made, and the device looks like it could be very cheaply made as well. And, the software looks like it's probably pretty crappy also. $320 is a bit too good to be true for what they are advertising, so chances are it's really not very good.

At $100 it would probably be a decent buy, but not at $320!.

Where is better for less found? Used does not bother me on solidstate. Ebay? I have the itch now..

Before Christmas I was shopping scopes all over Ebay. Outbid everytime as I was not 100% needing one. But there was a Tek DS2024 or something like that.. It was something. Darn thing went for like $1500. But it was awesume.

If you have the itch for a decent scope and have limited funds you can spend hours and hours on e-bay hunting an pecking individual bargains. The first thing you need to know is exactly what you need a scope for =) I bid on the first hunk of junk that came up on my screen and (including shipping and handling) got a 500khz dual trace scope for 30 bucks. Best purchase I ever made =)

In case I missed it, what's your current scope, and what do you use it for? I think the only mention you made your your scope was it was 20mhz? If it's analog it will probably out perform that digital jobbie by 10 to 1 for usefulness. 100 M/s's is nice. But Divide by four is barely human readable, Divide by 8 or 16 is better for human viewing, in which case the scope is only good for around 6mhz, if you need real signal resolution it's more like 1mhz or less.

I have a 20Mhz storage scope. I like it. I was thinking portable with my laptop. Budget is my problem.. I will go look on Ebay some more. Maybe get a nice 100Mhz for home and that the 20Mhz to the office and leave it there might be a better answer. Cost wise.

I got a reply from World Educational Services regarding the probes. The probes are switchable between 1X and 10X.
