USB Oscilliscopes
|
Don Bowen
I am looking at USB oscilloscopes for various projects and to maintain the club repeater. There are several on the market around $100 and under. Some are rated for 40MHz and have logic analyzer, spectrum analyzer, and other functions available. Has anyone experience and recommendations? I have an HP 200MHz scope but it is a pain to haul to the repeater to make audio adjustments.

USB means you need to haul a lap top. For audio work-
I have a smartphone sized scope.. I bought from Seeed studio's.. I have the DSO nano and the DSO quad... Actually I like the DSO nano better... I also use the $48 digital storage scope for monitoring SSB HF output in my shack..(I sample RF with a diode) I however bought that from china and found it for $35 a year ago. It's a hobbiest scope in china.. seeed0 studios DOES have 3 E's in the name...
? I did find a beautiful Tektronic TAS465- US coast guard surplus (with PMEL calibration tags) on ebay from a company in silver springs, md. (just outside of Washington DC) last month.That is sitting on my test bench..I was sole bidder on Labor Day- $119 I got it for...ebay member- telnetliquid-llc... he has an ebay store.. Finally, my DSO quad is for sale.. Used 2-3 times. looks new in the box.. It's going to the ENID OK hamfest next weekend. Regards to all... Larry W8LM....

I too am curious as I have been thinking of making such a purchase myself for radio work around the shack. ?I dont have any scopes anymore, and want to try something that takes up less real estate on the desk!

开云体育I haven't seen much in the advertisements that indicate what frequencies these devices cover.? For the cheap ones I've heard they will not cover many of the ham frequencies. 73, Alan - W6ARH ? ? From: Raspberry_Pi_4-Ham_RADIO@... [mailto:Raspberry_Pi_4-Ham_RADIO@...]

开云体育I would be interested if one of them went at least to 100MHz, 200MHz would be ideal. ?They all seem to be low frequency, e.g. 1MHz or less. ?Chuck

In its day (not all that long ago) it was a very expensive high quality item. I bought it got less than $200 but ut does take up a lot of real estate on the bench. -- Don Bowen AD0NB "A man must keep a little back shop where he can be himself without reserve.

I have noticed 20MHz and 40MHz.? Well more than good enough for audio but marginal for HF unless you are playing wound with the IF section. -- Don Bowen AD0NB "A man must keep a little back shop where he can be himself without reserve.
