ST 165 Wireless protocol detector

ST 165 is designed for detection and identification of mobile radio transmitters of cellular communications standards:

• Cell phones and modems of GSM 900/1800 and 3G standards;
• Wi-Fi devices and wireless 2,4 GHz video cameras;
• Bluetooth devices;
• Cordless phones (DECT).

ST 165 allows user to set the UMTC frequency according to local standards.

Product Description

ST 165 is a direct conversion receiver with digital control and a color OLED display for data output. In order to detect signals the ST 165 scans a series of frequency ranges of the known transmission standards. The user can set up the detection threshold and the number of desired frequency bands. Signals identification is performed on basis of analysis of detected signals time parameters.

Additionally indication of base stations power signal strength and data exchange intensity is provided.

ST 165 has 3 operation modes:
Automatic mode is used for signal detection recording events in the event log. The device provides scheduled operation.
Manual mode is used for localization of detected radio devices and set the threshold levels for further operation in Automatic mode.
Event log view mode is used for viewing the recorded events. The device has 30 databanks; each bank contains memory for 999 events.

Special software (comes with the device) allows doing the following:
• Display graphic of real-time of operation and event log results
• Manage the events database
• Control the operation of the device directly from PC using the USB connection or via ETHERNET
