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
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 !
SOME EXEMPLARY APPLICATIONS:
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.
