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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
