Decimator D4 RF Spectrum and Signal Analyzer
Advanced Spectrum Monitoring & Signal Analysis
The Decimator D4 spectrum and signal analyzer is designed for users with advanced spectrum monitoring and signal analysis requirements. Decimator D4 remotely monitors RF communications and detects signal issues.
Decimator D4 is a wideband spectrum analyzer with carrier monitoring that can be used for L-band, C-band, Ka-band, Ku-band, and Q/V-band frequency satellite signals, and is available in multiport, PCIe card and portable form factors.
It’s
ideal for
monitoring RF feeds and carriers in satellite, wired and terrestrial wireless
networks.
Decimator D4 Highlights Video
Decimator D4 includes a wide frequency range, DVB-S/S2/S2X signal digital demodulation with a constellation display, signal analysis, advanced carrier monitoring and more. Watch the video to see these features in action.
Decimator D4 Highlights
Decimator D4 is our newest generation spectrum and signal analyzer and has built-in carrier monitoring.
- Secure web browser user interface can be run on all devices
- Analysis frequency range 5 MHz to 6.5 GHz
- Carrier monitoring, cross-pol isolation measurement
- DVB-S/S2/S2X demodulation and signal analysis
- Constellation display and waterfall display
- For operators who have critical measurements to monitor, Decimator D4 offers programmable email & SNMP alarms that can be set up to notify multiple people immediately if a signal is out of pre-set thresholds
- Up to 10 concurrent remote users can connect to the Decimator D4 and perform ad-hoc measurements, a separate independent connection from your Network Management System (NMS) via the publicly available API can also be performing background measurements
Built-In Spectrum Monitoring
D4 is ideal for unattended monitoring of carriers in case of signal problems, satellite transponder compression or ground station equipment failure.
You can monitor up to 100 carriers within defined limits for power in a carrier and presence of a carrier. Any anomalies notify interested parties via email or SNMP when a signal is out of limits.
For enhanced spectrum monitoring, view the Spectator add-on option.

Cross-Pol Isolation Measurements
D4 measures and displays the cross-pol isolation of remote satcom and VSAT terminals.
Both co-pol and cross-pol signals are displayed at once, making it easy to see the measured isolation. The measured results can be exported and stored to provide a record of cross-pol performance during regular operation or carrier line-up.
This feature is only available for the multiport Decimator.

Spectator Add-On—Advanced Spectrum Monitoring
The Spectator software add-on license offers advanced spectrum monitoring capabilities for Decimator D4.
Spectator allows you to view up to 100 carriers at a glance in a single window, play back individual carrier traces, view trend plots and more.

API—Remote Management Protocol
Decimator includes an application program interface (API) for remote management, configuration, monitoring and automated measurements.
This API allows easy integration of Decimator into customer-furnished systems or products, such as satcom terminals, antenna control units, VSAT hubs and other similar systems.
The Decimator software includes an SNMP status interface for unit health monitoring.

Detector Add-On—Advanced Signal Monitoring
The Detector software add-on license allows users to display multiple signal constellation displays on a single screen.
Detector helps you monitor constellation diagrams from up to 100 carriers at a time for analyzing demodulated signal characteristics. The display also includes a historical view and trend plots.

Waterfall Display
Built into Decimator D4, Waterfall Display shows a heat map over time of the trace power values. All the current settings from the Spectrum view are loaded into the Waterfall view, such as center frequency, span and RBW for easy configuration.
This display makes it easy to see signal variation over time with a wide frequency range. Intermittent interference signals are easily spotted on the waterfall display.

Multiport Decimator D4
The multiport Decimator D4 is ideal for local or remote monitoring of multiple communications or broadcast carriers within a frequency range of 5 MHz to 6.5 GHz. The multiport unit installs in a 1RU 19” rack mount chassis and is available with either four or eight input ports.
PCIe Card Decimator D4
The PCIe card Decimator D4 is designed for integration in your own enclosure or in a computer PCIe slot.
Portable Decimator D4
The portable Decimator D4 fits into a standard laptop case and is useful for technicians to investigate problems in the field. The portable D4 is easy to set up and connects to a laptop for signal investigation on the go.
Web-Based User Interface
Decimator includes a built-in user interface that’s accessible using a standard web connection. All common spectrum analyzer settings and functions are available, including:
Save and recall configurations for quick repeat measurements
Export measurement results into reports for sharing or into spreadsheets or other applications for detailed analysis
Multiple markers make power level measurements easy to perform
Custom Versions Available
