Quick request!


I have a small request for you Guys:

When asking for an activation code, please mention which software version you want to activate (ADF/MAX or Siglent SSA3000X). If you just send me the system code, I cannot distinguish which version you need and the system code/activation code differ for both versions.

Also, please send me an e-mail, rather than using the blog's comment section or PM on different forums I use. My e-mail is stated in the user manual of the ADF/MAX version (when I have time, I will do a Siglent specific manual), but here it is: "v m a" without spaces in between at "norcam" dot "pt".

VMA Simple Spectrum Analyser for SSA3000X - Different visualization modes and measurements


Today I upload a new version of my "VMA Simple Spectrum Analyser for SSA3000X" software. The major new feature is the updated 3D rendering engine, as well as, a bug fix that makes the software run with either configuration of the decimal symbol under Windows (point or comma).

Take a look at the following screen shots of the local DVB-T transponder at 754MHz:

3D Spectrum view in shaded mode

3D Spectrum view in wireframe mode

Bandwidth measurement: -3dB and -6dB

Bandwidth measurment: -6dB

Live spectrum with MIN/MAX hold in shaded mode

Live spectrum against AVG trace in line mode

"FADE" visualization mode

3D spectrum in shaded mode - view can be rotated!

Same 3D spectrum in different view

Hope you find this interesting! If so, why not download the software and try it yourself?

  • The software *should* work fine without any installation: just unpack and start executable. You need to enter the IP of your Siglent SSA3000X.
  • The SSA3000X needs to be running on the latest FW 8.2. Older FW releases do not support SCPI over Telnet.
  • Currently you need to be running Windows 10 or Windows 8.1.
  • Please make sure you have Microsoft .NET 4.5 Framwork installed!
