Band Power 2 –3 Tuning (BPOW2 – BPOW3)
Description of Tuning
For this step the AGC_REF PDM is adjusted to provide an additional 10
dB of attenuation from the AT–109. The CDMA TX output bandpower will
then be approximately 1.0 dBm, 10 dB off from the 11 dBm set in the
previous tuning step. This bandpower position is referred to as BPOW3.
This 10 dB attenuation is the dynamic range that the AT–109 will operate
from.
– Use the Up, Dn, PgUp or PgDn keys to adjust the BPOW3 power level
to the target range.
– Enter the actual measured TX Power into the dialog box and press
<Enter>.
– Press <continue> for the next screen or <cancel> to exit without sav-
ing.
Band Power 3 Tuning (BPOW3)
Description of Tuning
This tuning step simply reports the BPOW3 bandpower position tuned in
during the previous step. This is the level of attenuation that the AT–109
will maintain when the phone transmitting below the Switch Point (15
dBm) while in CDMA operation power
– Use the Up, Dn, PgUp or PgDn keys to adjust a reference power level
into the target range and press <continue>.
TX Offset Tuning
Definition of Tuning
This tuning adjusts the mid–point of the TxDac register to correspond to
–8 dBm of TX output power, the mid–point of the TX output dynamic
range.
– Use the Up, Dn, PgUp or PgDn keys to adjust BPOW1 power level into
the target range and press <Enter>.
