9.8.4 The BTS Scanner
If you equip the R&S FSH with option R&S FSH-K50E or -K51E, the BTS scanner
becomes available.
If you are measuring over-the-air (OTA) signals, you can use the BTS scanner to
identify base stations in the area. Every base station is identified by its Cell ID. The
BTS Scanner shows the Cell ID for every base station it has detected. For every base
station it also shows the power graphically (each yellow bar represents an active and
detected base station) and numerically in a table above the diagram. The table also
shows the power of the S-SYNC or P-SYNC of the basestation.
Trace modes
Note that the BTS Scanner supports several trace modes.
If you are using a trace mode other than Clear / Write, the bars depicting the Cell ID
may turn grey. A grey bar is shown in case of base stations that have been detected in
the past but are not currently detected.
For more information on the trace modes see "Selecting the Trace Mode" on page 111.
