 RF Analyzer
The RF Analyzer displays detailed information from communication diagnostic on a web browser. You
can easily check to see how stable communications are and troubleshoot problems.
You can browse a list of diagnostic information and periodically confirm the leeway quantitatively on
graphs. You can download a log file that contains the diagnostic information stored in the Reader/
Writer to a computer for your usage.

The Reader/Writer operating time when it communicated with the RF Tag
The name of the query in the communication with the RF Tag
The diagnostic result (stable, unstable, or error)
The cause when a communication was unstable
The communications signal level between the Reader/Writer and RF Tag is displayed in 10
levels on a vertical bar graph.
The higher the value, the more stable the communications. A value of 10 means that
communications are stable, and the bar is displayed in blue. A value of 1 to 9 means that
communications are unstable, and the bar is displayed in yellow. A value of 0 indicates a
communications error. Adjust the installation conditions to get the values as close to 10 as
possible.
The ambient noise level around the Reader/Writer that was detected in communications with
RF Tags is displayed in 10 levels on a broken-line graph. The higher the value, the less stable
the communications.
