🧩 🧩 Detailed description of RTSA-Suite PRO software blocks
RTSA-Suite PRO software is built on a modular Drag&Drop system – the user connects coloured blocks using the mouse. Each block performs a different function. Below is an overview of key blocks:
🔷 ComboView
A complex block that combines three graphs into one window (classic graph, waterfall and histogram). Cursors and markers are mirrored, showing the same position in all views at once for maximum ease of analysis.
📊 Histogram (Persistence)
A clear graph showing the percentage occurrence and density of signals over time using colours. It is key for detecting hidden or extremely short transmission pulses (bursts).
🌊 Waterfall 3D
Displays the history and evolution of the frequency spectrum over time in a clear three-dimensional space. Old signals flow away like a waterfall.
📈 IQ Power Spectrum
A very important basic block. Converts raw I/Q data into spectral graphs using a highly optimized FFT algorithm, significantly saving processor (CPU) computing power.
🔊 AM/FM Demodulator
Converts radio waves into sound, allowing direct listening to radio transmission (e.g. classic commercial radio or aviation communication).
💻 Script
A block in which you can write your own JavaScript code and program specific functions as needed.
🌐 HTTP Server / HTTP Client (basic package)
Allow free sending of live measurements from the spectrometer over the internet anywhere in the world (one channel is completely free).
📶 Automatic Wi-Fi traffic control
To prevent corporate phones or laptops from triggering false alarms, the IQ WiFi Interaction Mapper block is deployed. This block reads MAC addresses, hardware vendors, SSIDs and protocols of all Wi-Fi devices in range in real time. The system compares them with the list of approved corporate devices. If it detects Wi-Fi communication from an unknown device, it immediately marks it as a threat.
⚙️ 24/7 detection principle
Differential measurement (two-antenna method)
Thanks to two independent receivers, the system compares inside and outside. The internal antenna is in the protected room, the external one outside. Normal external signals are captured by both antennas and subtracted. If a local source appears, the internal antenna detects a power increase and the system immediately raises an alarm.
Automatic database comparison
The system compares the captured signal with an extensive database of known protocols (Bluetooth, Wi-Fi, GSM, LTE, etc.). If the signal matches a known protocol, it displays its type. If not, it marks it as "Unknown threat / RF anomaly".
Learning the clean state (spectral mask)
In the initial phase, the system stores a reference mask of the normal radio background. If a new transmitter appears above this line, the system immediately evaluates it as suspicious.
🚨 Automatic system response, alarms and signalling
🔌 Physical activation of external devices (relay)
On alarm, the system closes the electrical circuit and activates a beacon, siren, signal jammer or electromagnetic door locks.
🌐 Intelligent network notifications
HTTP, MQTT and TCP commands for integration with camera system, BMS, or sending SMS/email to the security manager.

🛠️ 🛠️ Appendix: Operating instructions and troubleshooting
For smooth 24/7 operation of the system, we present official service procedures and solutions for non-standard states directly from the manufacturer's technical manual:
⚠️ Error "USB underflow" (Insufficient bus speed)
Occurs when the USB port cannot transfer data fast enough. Make sure the device is connected to a USB 3.x SuperSpeed port. Since the system will use synchronous measurement from both receivers (Rx1 and Rx2 simultaneously), for bandwidths above 122 MHz it is necessary to connect, in addition to the main data cable, an additional boost cable marked "BOOST".
⚠️ Error "DSP buffer overflow"
The computer cannot process data in real time. The solution is to slightly reduce the load – e.g. reduce the FFT size (graph resolution) in the IQ Power Spectrum block settings, or switch the data stream to Spectra format instead of IQ.
⚠️ Yellow "Power" indicator or red "Critical state" after start
Indicates that the computer's USB port does not supply enough power. The computer port must strictly comply with the USB-C 3.1 standard with Power Delivery (USB PD 3.0) support.
⚠️ Random disconnection of the device during 24/7 operation
Caused by power-saving modes of the Windows operating system. Set the PC power plan to "High performance". In Device Manager, open the properties for USB Root Hub / Generic USB Hub items and on the "Power Management" tab, uncheck the box "Allow the computer to turn off this device to save power".
⚠️ Automatic gain control (Amp / Preamp) in the ECO model
The device controls its sensitivity fully automatically according to the set Reference Level. At levels of -13 dBm and above, it protects the inputs by attenuation. From -14 dBm and below, it turns on the main amplifier, and from -33 dBm and below, it activates the preamplifier for maximum sensitivity to capture even the weakest bugs.
⚠️ Recovery of distorted data or calibration error
If the device shows anomalies in measurement, disconnect it from USB. Run the empty software, go to the top menu Extras -> Data -> Open Datafolder Global. In the opened explorer window, go to blocks/resources/ and completely delete the entire folder named after your Spectran V6 device. After restart, the device will download completely clean factory calibration data.
