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.
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.
@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?
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.
I had not heard of that logging multimeter till you posted this blog. That one will be an interesting one to watch here in the future. Also thanks for the mention of my recent blog post on the Red Pitaya. I am excited to get some more time to play with it here in the near future.
