Attention! We have switched to a new store engine!
Our online store switched to a new IT infrastucture on February 23, 2023. Old accounts created before 23.02.2023 still work and you can easily log in using your old access data. However, your purchase history from before 23.02.2023 is no longer visible in your accounts. If, as an old customer, you need your data for previous orders (placed before 23.02.2023), please contact us by email.
This category gathers professional spectrum analysers, field-strength meters and broadband RF detectors designed for teams who must understand—rather than guess—what is happening in the radio domain. From corporate TSCM sweeps and broadcast engineering to drone-defence zoning and police counter-intercept work, these instruments transform invisible signals into actionable insight, showing frequency, power, modulation and source direction in real time.

RF Survey – The Foundation of Technical Security
Every transmitter leaves a spectral fingerprint. A spectrum analyser scans wide swathes of bandwidth, measures amplitude over frequency and displays anomalies that betray hidden bugs, rogue base stations or malfunctioning equipment. Unlike simple “RF sniffers,” professional tools log peak, average and burst power, decode modulation hints and time-stamp events so reports stand up in court or compliance audit.
Core Measurement Capabilities
Wide dynamic range — cleanly resolves low-power covert bugs alongside high-power cellular carriers. Real-time persistence — captures µs bursts that vanish on slower sweepers. Waterfall recording — stores hours of spectral history for post-mission playback. Signal classification — built-in libraries tag Wi-Fi, Bluetooth, LTE, TETRA and analog FM at a glance. Direction-finding interface — vector outputs feed handheld or vehicle antennas to pinpoint emitters within metres.
Typical Field Workflow
A survey starts with a panoramic sweep—often 10 kHz to 12 GHz—establishing the ambient “noise baseline.” Operators mark licensed services, then focus on unexplained peaks. Real-time persistence reveals burst transmitters; demodulation tools listen for hidden audio. If suspicion remains, a calibrated antenna grid or a drone-mounted receiver triangulates the source. The final log exports as an encrypted dataset with GPS, UTC and device-health metadata, satisfying evidentiary rules.
Representative Use Cases
TSCM sweeps — locate GSM, Wi-Fi or DECT bugs buried in office ceilings. Drone-defence perimeters — monitor 2.4 GHz and 5.8 GHz ISM bands for controller links and trigger jamming only on threat signatures. Critical-infrastructure audits — verify that plant radios, LTE routers and telemetry links stay within licensed masks. Broadcast engineering — align STL hops, measure spurious emissions and document compliance for regulators. Law-enforcement stings — capture suspect pager or push-to-talk traffic before serving a warrant.
Frequently Asked Questions
How sensitive are these instruments? Professional receivers reach –160 dBm Hz-1 noise floor, sufficient to spot sub-milliwatt bugs across a boardroom.
Can they decode encrypted content? They reveal carrier parameters and burst timing; payload decryption requires lawful-intercept tools or access to the endpoint.
Are external antennas required? A telescopic whip handles 30 MHz–3 GHz; directional log-periodic or spiral antennas improve gain and DF precision.
Do multiple analysers interfere? Receivers are passive; several can run simultaneously without mutual impact.
Regulatory & Calibration Notes
High-speed spectrum analysers fall under EU Dual-Use 5A001.b when bandwidth exceeds 500 MHz; export or cross-border use demands an end-user certificate. Yearly calibration against a traceable signal generator keeps amplitude and frequency error within spec, ensuring measurements remain admissible in legal or compliance proceedings.
