Unidentified transmission
A signal appears in or near a band used by your equipment and its origin is unknown.
An unwanted or unknown signal is only useful to identify if you can determine where it is coming from. We combine spectrum analysis with on-site comparative measurements and direction finding to narrow down the source.
Source location is most useful when the interfering transmission is present long enough to measure and distinguish from normal site activity.
A signal appears in or near a band used by your equipment and its origin is unknown.
A measurable signal correlates with loss of service or reduced performance.
Measurements indicate the problem is generated on or close to the affected site.
Electrical or electronic equipment may be radiating energy unintentionally.
The signal appears and disappears as equipment, vehicles or processes move.
You need measurements that support a practical engineering conclusion rather than speculation.
The exact technique depends on frequency, signal behaviour, site access and whether the source is continuous or intermittent.
Record frequency, bandwidth, level, timing and other distinguishing behaviour.
Measure how the signal changes across the site and relative to the affected equipment.
Use appropriate directional techniques where the signal and environment allow.
Reduce the search area and, where possible, verify by correlation, isolation or controlled switching.
Describe the symptoms. We’ll tell you whether an on-site RF investigation is likely to help.
