(R) RSSI Trigger Level
The RSSI Trigger Level is selected with the ‘R’ key. The Received Signal Strength Indicator (RSSI) trigger
sets the signal level required before the Crescendo-series RFI-150 will respond. RSSI is measured in
dBm (usually negative values). A value of –60dBm is a stronger signal than –80dBm.
The default value is –110 dBm
. This value should be increased in noisy RF environments to prevent false
triggering.
When selecting this option, the following instruction is presented on the screen:
Enter RSSI trigger level as dBm (-140 to -40): -110
