I am posting this for an EE engineer friend, need suggestions/link(s) to a USB Spectrum Analyzer. The more compact the better...
Thanks in advance...

waht said:Hi Rhody, Picoscopes could be a good option:

But it all depends on the application the scope is to be used for. If your friend wants to fork out more than $400 bucks, than consider getting a Rigol normal scope which is ten-fold better than any usb scope at that price range:

Topher925 said:The USB based scopes are borderline worthless for most applications other than learning about electronics. The Rigol and Instek scopes are very good if you are on a budget or a hobbyist. If you don't mind buying second hand, ebay is a good source for DSOs as well. I got my Agilent DSO3102A with cal certificate for under $500 shipped from ebay.
If you are looking for a analyer that does more than FFT with basic windowing you're going to have to start shelling out some serious cash. If you have a scope with a decent sampling rate and memory depth you can export data to a PC and analyze it. I've done this using an old Tek TDS210 and matlab. Its not the most elegant solution but it works.

he says he is now considering building his own
waht said:What frequency range is he trying to analyze?
If it's audio, there are programs that utilize your computer's sound card as an audio spectrum analyzer. There are also nice iphone spectrum analyzer apps too.
A USB spectrum analyzer/oscilloscope is a device that allows you to measure and analyze electronic signals, frequencies, and waveforms. It connects to a computer via USB and uses specialized software to display the data in a user-friendly manner.
A low cost USB spectrum analyzer/oscilloscope is needed because traditional spectrum analyzers and oscilloscopes can be expensive and out of reach for many individuals or small research laboratories. A low cost option allows for more accessibility and affordability for those who need these tools for their work.
A USB spectrum analyzer/oscilloscope has a variety of uses, including troubleshooting and testing electronic circuits, measuring signals in telecommunications, analyzing audio signals, and even scientific research in fields such as physics and astronomy.
Most USB spectrum analyzers/oscilloscopes require a computer with a certain operating system and minimum hardware specifications for optimal performance. It is important to check the device's compatibility before purchasing.
While a low cost USB spectrum analyzer/oscilloscope can be a useful and affordable option, it may have some limitations in terms of frequency range, bandwidth, and accuracy compared to more expensive models. It is important to carefully research and consider your specific needs before purchasing a device.
