Re: Best inexpensive electronic testing programs/equipment using PC

From one Rick to another...

Here are the Aps. that I use and recommend. The price/performance is excellent as they are all free.

Visual Analyser 8:
An integrated suite from Italy. This is probably the sort of thing that you are thinking of. I usually use the FFT analyzer, but it's got most everything. There is a learning curve as the UI is a bit idiosyncratic, but logical in it's own way once you figure it out. I have experienced memory leakage on some machines so keep an eye on RAM usage when you start and stop it. I just relaunch the program if it bogs down. The only other problem I've had (unless you count my preamp putting out over a kilovolt per it's voltmeter) is with 24 bit A/D support. The author is apparently working on that issue but I don't know if it will get resolved for USB devices. I just downloaded a new update while writing this so perhaps it will magically work. This program has available the longest FFT's of this batch and is my first choice for seeing close in spurs.

DaqGen 1.4:
Is a nice, standalone generator.

WaveTools:
By Paul Kellett is an older, but quite usable set of tools for 16/44. I often use the level meter and that's good as the spectrum analyzer works better when the level meter is running!

Spectrogram 5:
This is a surprisingly capable FFT analyzer once you figure out how to set it up. It updates very rapidly so you can watch what's happening spectrally in real time. It's also very easy to capture screen shots. I use it frequently.

That's about the crop, in general they have three things in common:
1. The price.
2. FFT performance suitable for electronic design and validation.
3. Idiosyncratic user interfaces.

I've come to appreciate the performance of these applications and now think of the UI's as charming and unique...
