I use AUDio MEasurement System with USB-Audio 2.0 adaptor - HD USB Audio AS372N 192 kHz 24 bit mode is great! I can use it to output 80 kHz signal all right. I use oscilloscope to check the output waveform. I think, it is possible to make VNA - Vector Network Analyzer with it. Just add series current sense resistor and output 60 kHz sine wave and measure the source voltage and voltage between device under test, you can get both voltage and current. You can get impedance of the device under test.

Nice and small! BUT... would like to have sweeps available.

Hi uniguy What is your use case for sweeps? Have you noticed that you can use white noise and get an instant frequency plot in the spectrum?

Generates signals OK, but quit responding when [File] was selected on Windows 10 Home 64-bit 10.0.18362. No installation required! Yay!! Does not generate arbitrary frequencies (e.g. exactly 400Hz), but is a nice simple utility for testing with constant tones. Pink and/or white noise would be nice to have..

White noise has been added recently. Please give it a try.
