GSM and EDGE Analyzer
Metrics Provided by the GSM and EDGE Analyzer
Measurement
This section contains descriptions of the individual GSM transmit parameters in the
metrics display of the screen. The “Interpretation of GSM Tx Analyzer
Measurement Results” section contains expected result values and possible causes
of error if the expected results are not met.
Frequency
Frequency of the channel indicated by the vertical yellow line on the Channel
Scanner display. The position of this yellow line can be adjusted by using the
[Display], [Position] menu keys. For further details, see “Setting the Display
Position” on page 349.
Frequency Error
Frequency error is the frequency difference between your transmitter's actual center
frequency and the frequency (or channel) you entered.
BSIC (Base Station Identification Code)
A two digit number that identifies the base station for the indicated channel. It
consists of the PLMN color code with a range from 0 to 7, and the S color code with
a range from 0 to 7. The BSIC is shown in Decimal format (8 * NCC) + BCC. For
example, if the NCC is 4, BCC is 3, the BSIC will be 35 (4*8+3 = 35). BSIC is
transmitted on a synchronization channel and is used to identify a cell and to
indicate the timing sequence being used.
• BCC = Base station Color Code
• BSIC = Base Station Identity Code
• NCC = Network Color Code
• PLMN = Public Land Mobile Network
TSC
TSC (Training Sequence Code) is a single digit integer from 0 to 7, “n/a (Sync)” if
the demodulated slot is a GMSK Sync burst. The training Sequence is in the center
of every burst, and is used to determine the start and stop of the useful part of the
burst.
