Notes:
1. Only when Call Process state is “Stop”, this item can be set.
2. The items of Using Specification, Band, and Channel determine this item
uniquely.
3. <Reference Level, Auto Set>
Reference Level sets the TX level of mobile station (input level to
MT8801C).
For the burst signal, it indicates the average power in burst.
When Auto Set is On, Reference Level is automatically changed depending
on the BS Output Level.
Normally, set Auto Set to On.
When Auto Set is On and Reference Level is set, Reference Level is set to
the specified value.
When the BS Output Level is changed, the Reference Level is also changed
to the corresponding value.
Reference Level = – BS Output Level [dBm]
+ K
+ NOM_PWR [dB]
+ INIT_PWR [dB]
(IS-95A, TSB74, ARIB-T53: K=-73, J-STD-008, KOREA-PCS: K=-76)
4. <BS Output Level (Total)>
BS Output Level (Total) sets the TX level of the base station (Forward
channel output level from the MT8801C).
It indicates the summed power of the Pilot, Sync, Paging, Traffic, Power
Control, and OCNS channels., where AWGN power is not included.
5. <AWGN Level>
The MT8801C has a AWGN (additive white Gaussian noise) generator to
add the AWGN to the TX signal of the base station (Forward channel out-
put signal from the MT8801C).
Set to ON to perform RX measurement under AWGN.
AWGN Level sets the AWGN (AWGN generator of the MT8801C) level
within the 1.23 MHz bandwidth.
It sets the relative value to the TX level (BS Output Level) of the base
station, and displays AWGN absolute power within 1.23 MHz bandwidth.
6. <Access Parameter NOM_PWR, INIT_PWR>
These parameters are specified from the MT8801C to the mobile station to
be set at the access parameter message in the Paging channel.
NOM_PWR and INIT_PWR are the nominal TX power offset and initial
power offset for access, respectively.
