CATS-01
Scanner
Scanner is intended to monitor RF communication with respect to RF channels. See IQRF OS User's guide for more
information about displayed parameters.
Scanner main screen
Activity in individual channels and parameters of RF signal in selected channel are monitored. All 62 channels (0 to 61) of
868 MHz band can be monitored at the same time but 186 channels of the 916 MHz band must be separated to three
groups and the user selects just one of them to be scanned and currently displayed.
Additionally, selected group can be reduced by the user. Channels are scanned one by one. Scanning of one channel
takes about 0.4 ms. Thus, to get higher resolution, number of scanned channels can be reduced by Low/High channel
limits. See
Scanner settings
.
The screen is separated to following parts:
•
RF activity in individual channels (1). The following information is displayed:
•
Whether a communication is running in individual channels. Active channels are displayed by bars.
•
Signal strength (current as well as the maximal detected one). Heights of bars are proportional to signal strengths.
•
Dark blue
Current RSSI in the channel
•
Light blue
Max. RSSI detected in the channel
•
Dark red
Current RSSI in currently selected channel
•
Light red
Max. RSSI detected in currently selected channel
•
Black horizontal line
RF level defining minimal incoming signal strength to be detected. See RF filter.
•
Red vertical line
Currently selected channel
•
Details about currently selected channel (2).
•
RF Band
Selected RF band
•
Channel
Selected RF channel
•
RF Filter
Specified RF level to filter incoming signal.
•
RSSI
Current RSSI value in selected channel.
•
Max. RSSI
Maximal RSSI value detected in selected channel
•
Scan CH
Selected group of scanned channels (3)
•
Area with four control buttons (4):
•
"<" and ">"
Channel selection (to display details)
•
Clr
To clear Max. RSSI values scanned and displayed up to now. The same can be achieved
by double click to the field (1).
•
Set
Switch to the
Scanner settings
screen for setting of scanning parameters.
