Change log:

2017-05-30: Added "Wait" parameter, which allows to set a pause between capturing each sample

Minimum hardware requirements:

The bottleneck is the SMA device itself! The software works well on any fairly modern computer, laptop or tablet. No matter if Intel Atom or Intel Core i7, expect a good performance. No special graphics card is needed.

You do need to have one free USB port to connect the SMA device! 

Operating System requirements:

The software only runs on Windows 7, Windows 8/8.1 and Windows 10.
No installer is used - just uncompress the archive to a folder and run the executable.

Licencing:

The software is closed source and requires a license. There are two types of licenses:
  1. Free temporary license - exiry date always set for the closest of these dates:
    1. March, 31st,
    2. June, 30th,
    3. September, 30th
    4. December, 31st
  2. Permanent license, provided to donators (10€, 10£ or 10US$ - instructions inside the software and in the manual)
New temporary licenses can be requested for free after expiry for free.

One user can request several personal licenses (free or permanent) within a reasonable amount, to allow running the software on PC, laptop and tablet.

Supported SMA devices:

  • 138MHz-4.4GHz USB SMA Signal Source Signal Generator Simple Spectrum Analyzer
  • 35MHz-4.4GHz USB SMA Signal Source Signal Generator Simple Spectrum Analyzer
  • 23.5MHz-6GHz USB SMA Signal Source Signal Generator Simple Spectrum Analyzer
  • NWT4000-1 138MHz-4.4GHz Sweep Simple Spectrum Analyzer Signal Generator
  • NWT4000-2 35MHz-4.4GHz Sweep Simple Spectrum Analyzer Signal Generator
  • NWT4000-3 50KHz-4.4GHz Sweep Simple Spectrum Analyzer Signal Generator
  • NWT6000 25MHz-6GHz Sweep Simple Spectrum Analyzer Signal Generator
The first two are low-cost models (60-70 Euro) featuring only one ADF4350 or ADF4351 synthesizer chip.
The third one is a low-cost model (110-130 Euro) featuring only one MAX2870 synthesizer chip.
The NWT4000 models (160-350 Euro) have two  ADF4350 or ADF4351 synthesizer chips.
The NWT6000 model (300-350 Euro) has two MAX2870 sythesizer chips

These devices can be purchased on eBay - search for "SMA Source/Signal Generator/Simple Spectrum Analyzer", "NWT4000" or "NWT6000".

Note: Currently the software only supports a maximum frequency range of 23.5MHz to 6GHz.

  2. Dear Zeljko: of course the software works on Windows 10. Please read the manual and the onscreen instructions. If you have any problem or question, please send me an email instead of commenting on the posts. My email can be found in the manual and is shown inside the software, too.
