Cassandra TM9

Purpose
The Cassandra TM9 radio monitoring and digital signal analysis system is designed for 24/7 continuous RF surveillance of facilities, detecting unauthorized transmissions—including those using complex concealment algorithms—and analyzing digital communication standards. The system can also function as an IQ recorder with a capture bandwidth of up to 40 MHz.
Functionality

Conducts real-time spectrum monitoring across its operational frequency range
Saves spectrum panoramas, individual signal spectra, and key RF parameters of detected signals to a computer
Supports signal recording and post-processing

Network Operation

Multi-system integration: Two or more units can form a unified monitoring network with a central control station
Centralized management: Operational data from all units is aggregated on the control PC via I_RemoteCheck software, displaying:
Signal detections
System status (power on/off alerts)
Comparative spectrum analysis between units

Design Specifications

Integrated design: Built-in RF processing unit (RPU) with ADC module, controlled via 1 GbE LAN
Compact form factor:
45mm ultra-low-profile monoblock
Dual mounting options:
19-inch rack installation
Flexible placement (ceiling voids, wall cabinets, etc.)
24/7 operational readiness
