Making good things better ?
Sure !

Basing on the reliable standard model we introduce with the DX version a new model
with extended hardware and software capabilities.

Many suggestions are originated by our customers:

• Additional DX mode for higher sensitivity
• Four programmable converter LO frequencies
• Higher frequency zooming resolution including zero-scan (0MHz/DIV)
• Visible basic noise level
• Higher dynamic range

SAT Spectrum Analyzer DX

Satisfying highest demands ...

The additional DX mode is a high-light, that makes weakest signals visible, which otherwise would be burried in the noise.
Therefore the minimum sensitivity improvement is typically 5-10dB compared to the standard version.

This is possible due a refined calibration procedure in combination with extended
internal memory capacitity.

It is also possible to upgrade the SpectraBox standard version, but this requires a new calibration. More details on request !


  • Spectrum monitoring, surveillance & signal identification

  • Measurement of cross polarity separation & C/N

  • Detection of radiation leakage & interference and signal sources

  • Broadband measurement of insertion gain or loss

  • Antenna adjustment & satellite searching e.g. VSAT

Test Report:

Christian Mass: NTi SpectraBox SAT - TELE-satellite International 10-11/2002

A test report of our Satellite Spectrum Analyzer SpectraBox is available in issue 10-11/2002 of the world`s largest satellite magazine TELE-satellite International (pages 93&94).

Some equotations:

" ... This device is more than just a spectrum analyzer. If it is used only for setup of an antenna, many of its features wouldn`t even be used. ... The logical menu arrangement and its excellent signal processing deserve high praise."

OPTION Auto Resume:

The AUTO RESUME version stores automatically all selected parameter settings for reference level, DX-mode (on/off), measurement range (L/H), amplitude scaling, center frequency and frequency scaling.

This firmware is also available for former models of the SpectraBox SAT DX, but therefore the device needs a new factory calibration.
