RSSI is a multisignal tracking metric that is particularly
useful for measuring power-level variations over time.
The RSSI measurement lets you assign a power limit line
for audible alarms and increase alarm counters every time a
signal exceeds a defined limit line.
For long-term analysis, the Spectrogram and RSSI mea-
surements can be automatically saved into an external USB
memory. Post-analysis can be performed with JDViewer
application software.
Interference Finder is an automatic triangulation algorithm
that uses GPS coordinates to locate possible interference
sources based on three measurements.
The interference finder calculates possible interference loca-
tions using its inscribed circle or circumscribed circle based
on measured intersection points.
Spectrum Replayer lets users retrieve and replay recorded
spectrum analyzer traces in interference analysis mode.
These traces can be played back in the Spectrogram or RSSI.
Users can configure the limit line to create failure points
when signals exceed it. The failure points are clearly displayed
on the trace timeline for quick access during playback.
Dual Spectrogram* captures the spectral activities for two
different bands over time to identify periodic or intermittent
band signals.
