Figure 4 Example of an RF History Strip
Received Signal Strength
The RF History Strip Recording shows two graphs of the
received signal. The upper graph, channel 1, shows the
received signal strength for each receiver over time. The
received signal strength, or RSSI count, is a value that
corresponds to the power of the signal in decibel
milliwatts (dBm). Table 4 shows the relationship
between the RSSI count and the actual power received
for M2603A receivers with firmware revision 2 installed.
The RSSI count on the strip is the same value that
appears in the RF INOP. The signal strength graph uses
the top four large boxes on the recording strip.
Note
Received signal strength values from M1402A receivers
and M2603A receivers with firmware Revision 1 are not
calibrated.
