Measuring the RSSI
Measure the RSSI value with a multimeter connected to the RSSI test port on the front of the terminal
(see "
Front panel connections and indicators" on page 27).
1. Insert the positive probe of the multimeter into the RSSI test port, and clip the negative probe to
the chassis of the terminal (earth).
2. Pan and tilt the antenna until you get the highest VDC reading. The values shown in the table
below relate the measured VDC to the actual received signal level in dBm regardless of bandwidth
and frequency.
