LTSpice is not portable software, as it requires an install on a PC or Mac. But yes it is a very good test tool from LT.
But by the way the tools listed here are very nice collection at a stretch, among them Red Pitaya seems to be of trande setter potential being a open source. Also it is nice of Gabotronics that they have revealed the schematic diagram of the product they are yet to commercially available.
@Sanjib - I am hoping to get an Analog Discovery next year and if I do I will try and let you know how it goes. Everything I have heard about them has been good. Anyone else have hands-on experience with them?
Great to learn about "Analog Discovery" from Digilent. Thanks!! Looks to be a professional product for low speed lab work and handy for debugging as it is multipurpose: oscilloscope cum logic analyzer cum multimeter. Ease of portability makes it good to place the tool on the desk instead the requirement for a lab space. Requesting your comments after you get a chance to try that.
I think any list like this ought to mention two more items:
1. The National Instruments MyDAQ
NI gear is usually pretty expensive (as is the LabView software needed to drive it) but if you are a student you can get their MyDAQ, which is intended for student use and is cheap ($99 for students with a copy of LabView), but it is only 200 KSPS / 20KHz bandwidth which I find woefully inadequate - even the low range items above do 2 MSPS and 200 KHz Bandwidth. Nevertheless it is a versatile goodie - has digital I/O and a DMM built in - and quite good value if you're a student.
2. Digilent Analog Discovery
Digilent make the Analog Discovery which is $99 if you can get the student price, a bit more otherwise. 100 MSPS 14-bit channels and they claim effective 5 MHz bandwidth - plus digital I/O. I'd like to get one of these - streets ahead of the MyDaq.
Both of these are USB/PC based, so no good if you want something standalone.Both are intended for the educational area, but still useful for low speed lab work.
