Key facts
R&S®GSACSM communication system monitoring is a SATMON software solution for remote spectrum monitoring and signal analysis. R&S®GSACSM comes with classic spectrum analyzer functions, trapping systems and advanced signal detection and identification algorithms.
Autonomous spectrum scanning and SATCOM carrier identification
The R&S®GSACSM classification feature enables autonomous scanning of spectrum signals and carrier identification. Carriers are visualized in color-coded charts and lists. The chart and list elements make identifying each carrier easy. The sniper tool can add new areas to select a specific carrier for further processing. All collected signal parameters and constellation diagrams are displayed.
Software-based signal demodulation
Can identify a huge variety of modulation standards and types (DVB-S, DVB-S2, IESS, GSM, etc.)
Identifying of underlying signals with carrier-in-carrier detection
PCMA detection and signal identification systems that use R&S®GSACSM can detect and identify paired carrier multiple access signals (two carriers with the same carrier frequency and baud rate). Identification of suspicious interferers with undercarrier detection to identify unwanted asymmetric signal sources beneath a useful signal.
Software-based carrier cancellation
The SATCOM carrier is canceled in order to identify the under-carrier signal.
Continuous spectrum scanning and demodulation of DVB-CID signals
Modern satellite communications need to efficiently avoid frequent signal interference. The Digital Video Broadcasting organization specifies a carrier ID (CID) that identifies the host carrier to effectively reduce interference between satellite signals. R&S®GSACSM can handle CID signals, meaning it can detect and demodulate them. The CID-specific “global unique ID”, the GPS coordinates and the telephone number are extracted.
DVB-CID demodulation
The demodulation is repeated until all CID parameters are captured.
Easy carrier monitoring with multichannel service tables
R&S®GSACSM monitors signal parameters with multichannel service tables. R&S®GSACSM can set alarm thresholds to inform users of unwanted signals. Users can define spectrum signal masks to immediately identify every suspicious carrier.
Signal monitoring with service tables
Various monitoring objectives can be set: C/N, signal power, signal bandwidth, modulation, FEC rate etc.
Scalable client/server architecture
In a scalable client/server architecture, R&S®GSACSM allows remote spectrum analysis in distributed systems. Operators can manage their instruments (RF components, e.g. R&S®NRQ6) in different locations. R&S®GSACSM supports the following Rohde & Schwarz sensor instruments:
