5.
Select Forward Link.
6. Tap the Channel box and enter a valid channel number for the
current standard.
Table 3--14 describes the GSM/EDGE RF Power measurement fields.
Table 3- 14: GSM/EDGE Power vs. Time fields
Field Description
BCCH The slot 0 signal source. Valid signal sources are
None, On Meas Chan/Freq, On Channel xxx, and On
Freq xx.xxx, where xxx and xx.xxx are the numeric
values for a channel or frequency, respectively. See
page 3--78 for information on setting the BCCH signal
source (frame sync mode).
BCCH Slot 0 Pwr The BCCH slot 0 average power value. The BCCH
slot 0 power measurement value is always in dBm
(absolute).
Note that the BCCH Slot 0 Power value is displayed
only if the BCCH Frame Sync control is not set to
OFF, a valid BCCH channel is present, and frame
sync is acquired.
Restart Clears all multi-slot averaged measurement and count
values and then restarts the averaging process.
Limit Test Shows whether any measurements are outside the
defined limit test values. See page 3--138 for
information on enabling limit testing.
Current column The current power value and modulation type for each
slot.
GMSK column The average power reading and number of
acquisitions averaged (count) for GMSK signals for
each slot. See page 3--80 for information on setting
the number of acquisitions to average.
8-PSK column The average power reading and count (number of
acquisitions) averaged (count) for 8-PSK signals for
each slot. See page 3--80 for information on setting
the number of acquisitions to average.
