[NLRS] Low-cost oscilloscope

[Glen Overby]

Donn suggested that this product would have some interest within the NLRS.
This was from the softrock mailing list.

I don't own one (I'm considering it) and have no pecuniary interest in the
product.

To add to what Jose said, I would suggest you take a look at the
DSO-2250 line of USB Oscilloscope (e.g.
http://shop.ebay.com/i.html?_nkw=usb+oscilloscope+DSO-2250&_sacat=0&_trksid=p328
6.m270.l1313&_odkw=usb+oscilloscope&_osacat=0
 
I have the DSO-2150 scope (150MSPS).  The newer 2250 is 250MSPS and
the price point seems to be around $300 (before shipping costs).
The seller (taomore) has a 99.4% rating on ebay.
 
These are connected to the PC with and powered by USB cable.  They
come with two probes.  The software runs under all of the Windows
OS's.  The software implements both an Oscilloscope and a simple
Spectrum Analyzer.
Some of the specifications are:
 - Impedance  1MOhm 25pF
 - Vertical resolution  8Bit
 - Gain range  10mV-5V, 9Steps
 - Timebase range  4ns-1h, 38 Steps
 - X-Y  Yes
 - EXT. input  Yes
 - Trigger Mode  Auto, Normal and Single
 - Trigger level adjustable  Yes
 - Trigger Type  Rising edge, falling edge
 - Trigger Source  CH1, CH2, EXT
 - Shot bandwidth  DC to 100MHz
 - Max. Sample rate  250MS/s
 - Vertical mode  CH1, CH2, Dual, ADD
 - Cursor measurement  Yes
 - Spectrum analyzer
 - Channel  2 Channels
 - Bandwidth  100MHz

It's not lab-quality, but is fine for hobbiest work.
