Attach a performer, device, service, or other description to each monitored frequency or band.

Watch what matters.Catch what changes.
Signal Watchdog monitors a defined list of frequencies or bands and reports whether each is clear or occupied—now and across recent history—without requiring someone to stare at a full spectrum trace.
Included with Wireless ToolboxChoose the RF Explorer or RTL-SDR edition, build the watch list, set a threshold, and leave the appliance observing.

Focused RF supervision
A full spectrum is often more information than the job requires.
Reduce a wide sweep to the assignments, links, or bands that must remain healthy.
Signal Watchdog sweeps a defined span, extracts the strongest measurement for each selected row, and compares it with the threshold you establish. The table presents the current amplitude and a rolling clear-or-occupied history for every entry.
Use it for wireless microphones, broadcast channels, repeaters, control links, telemetry, or any known allocation where an unexpected signal—or the disappearance of an expected one—deserves attention.
Diagnostic capabilities
Convert spectrum data into operational status.
The underlying sweep remains visible, but the watch list translates it into the named frequencies and bands that people actually manage.
02
Immediate threshold state
Amplitude bars show current strength and change color when a row crosses the configured level.
03
Rolling event history
Recent green and red samples reveal whether occupancy is isolated, intermittent, or persistent.
Field workflow
Define the watch list once, then supervise continuously.
Monitor specific frequencies or the strongest signal anywhere within defined bands.
Establish the swept range and the dividing line between clear and occupied.
Build a watch list that reflects the channels, people, or systems being managed.
Use current amplitude and the last 100 sweeps to identify changes and their persistence.
The instrument view
A spectrum sweep translated into a watch list.
Frequency and band modes let the same instrument serve narrow channel assignments and broader allocations.
General RF Spectrum Analysis
Know when a critical signal appears, disappears, or changes.
Signal Watchdog keeps attention on the frequencies that matter while preserving enough history to understand the event.
