Calian PCIe Card Decimator D4 Spectrum & Signal Analyzer

The Decimator D4 Spectrum & Signal Analyzer is a fourth generation spectrum measurement and analysis card, providing high-end performance at a low price. It can function as either an independent spectrum analyzer in a satellite, cable or terrestrial network or can easily be integrated into a satellite terminal, equipment enclosure or as part of a larger measurement network.

Decimator D4 uses state of the art digital technology and Fast Fourier Transformations to make fast and accurate measurements.

With a very low noise floor and large dynamic range, it is well-suited to measure any type satellite, cable or terrestrial wireless carrier, including very small carriers, beacon signals and for carrier monitoring applications. Decimator accepts all signals from 5 MHz to 6.5 GHz and input power levels ranging from –110 to +5 dBm. RBW varies from 1 Hz to 15 MHz. The Decimator can be connected to an external 10 MHz reference for improved frequency accuracy and stability. All data communications with the Decimator occurs via the built-in Ethernet port.

The signal analysis engine demodulates and decodes the MPEG transport stream based DVB-S/S2/S2X signal and provides signal characteristics, modulation accuracy, power measurements and constellation display to view the digital modulation quality.
