If you want to talk about specific pieces of test equipment, maybe you should post a somewhat different question in the Test Equipment forum.  Reword it so it doesn't look like a duplicate post.

There aren't all that many handheld scopes around.  It's kind of a niche deal for industrial electricians - think radio bridge crane controls where 4 lift units are slaved to move the fuselage of a DC-10 down the assembly line.  Been there, done that...  We didn't have those nice Fluke scopes but they sure would have been handy - way up there!

What is probably better is a bench scope with as large a screen as you can get.  Then with a built in web server, you can read the scope on a 27" display.

Read the thread before considering the title.  Sometimes people get confused...

If you are considering the older Analog Discovery, the only functional difference is an added variable supply with a 5 volt max. The AD1 can actually do the same thing from the wavegen outputs, though you do tie up one of the outputs in the process. The case of course has been redesigned to be eye catchy, but in an operational sense they are pretty much the same unit. Add an inexpensive power supply and you are back to square one. I bought a couple of the older HP 6216A single output power supply's on ebay and I have a much more functional setup than using the AD2's built in supply.

Actually, the AD2 power supply can make use of an external wall wart to drive more power output than you can get with the USB connection.  The original AD is very limited on current output while the AD2 can go quite a bit higher


--- Quote ---Two programmable power supplies (0…+5V , 0…-5V). The maximum available output current and power depend on the Analog Discovery 2 powering choice:
250mW max for each supply or 500mW total when powered through USB
2.1W max for each supply when powered by an auxiliary supply
700mA maximum current for each supply

The original Analog Discovery was limited to 50 mA from each supply.  This USB limit is where the 250 mW number comes from above.  Being able to get to 2.1W is pretty nice!

Once you’re adding an external wall wart to the AD2, you’ve lost any added value IMO. A very cheap and small regulated supply could just as easily be added that would provide much wider voltage and current capability.

Some folks around here are very fond of Picoscopes - apparently their software is quite good.

At a price within your range, and suitable for analog audio and some limited digital debugging, are two eBay listings:
Picoscope 2202 (2 channels, 2MHz@20MSPS) - new with warranty
Picoscope 2203 (2 channels, 5MHz@40MSPS) - used with warranty
