Calian Multiport Decimator D4 Spectrum & Signal Analyzer, 8 port 5Mhz-6.5Mhz, 50 ohm

The Multi-Port Decimator D4 is a fourth generation spectrum measurement and signal analyzer unit with several built-in features like carrier monitoring, cross-pol measurements and DVB S/S2/S2X signal demodulation and signal analysis.

The HTML5-based user interface allows the D4 to be operated from all browsers and on all platforms. With a powerful internal dual-core processor, D4 uses state-ofthe-art digital technology and  Fast Fourier transformations to perform fast and accurate measurements.

Decimator has a very low noise floor and a large dynamic range that’s ideal for measuring any type of satellite, cable or terrestrial wireless carrier in a teleport, cable headend, wireless or broadcast facility. It accepts all signals from 5 MHz to 6.5 GHz, and input power levels can range from -110 to +5 dBm, making the D4 ideal for measuring both high and low power signals in carrier monitoring applications.

The Multi-Port D4 comes with an integrated 8-port RF switching capability and is available with either a 4-port deployment to an 8-port license via a software license key. The powerful Graphical User Interface (GUI) is available using any HTML5 standard web browser, no additional software is required.

The GUI is easy to use and operates like a traditional spectrum analyzer. It provides user-selectable colors for markers and traces, allows storage of multiple traces and provides measurement reporting. The Carrier Monitoring function provides notification via email or SNMP of carrier measurements that exceed user‑defined thresholds, offering peace of mind that carriers are operating as expected.

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.

The Cross-Pol Isolation measurement function allows display of Co-Pol and Cross-Pol signals simultaneously, along with the isolation value. All data communications from the user interface occurs securely via the built-in Ethernet port using HTTPS. The D4 provides network access to all staff connected to the facility network or a corporate wide area network. Staff can monitor feeds and carriers at any time and from any location in the world using only a web browser. For integration into a larger measurement or carrier monitoring system, the Decimator can be operated via its built-in GUI or the user can create a separate user interface using the publicly available API.
