The power available from the tester depends on the connector in use. When using the RF IN/RF OUT connector, the
power range, assuming no external attenuation or gain, is –133.0 dBm to –70.0 dBm to –19.0 dBm. When using the RF
OUT 2 connector under the same conditions, the power range is –113.0 dBm to –70.0 dBm to +1.0 dBm.
132
If external gain or attenuation is used (through the command tree ”SOURce:CORRection: LOSS:...”), the internal power of
the tester is adjusted to maintain the commanded power after the attenuation or gain. However the limits will change. For
example, if there is 10 dB of external loss (attenuation), the output range for the RF IN/RF OUT connector will be –143.0
dBm to –70.0 dBm to –29.0 dBm. Note that the default power remains the same provided that the tester can output the
required power, given the external attenuation or gain.
133
If the tester is in the IDLE state, the power range accepted as defined by the MAXimum and MINimum arguments, or as
returned in response to the MAXimum or MINimim queries, is the widest range which can ever be obtained using either
RF output and the full range of attenuation and gain values accepted by the ”SOURce:CORRection:LOSS...” command
tree (–183.0 dBm to –70.0 dBm to 41.0 dBm). If the output power is set outside the limits that the tester can produce, when
the instrument leaves the IDLE state the power will be set to the closest end of the range for the output connector and
external attenuation (or gain) in use.
134
Value must be changed using the BS configuration command.
135
The secondary PN Offset can only be set if there is no power in the secondary sector. It cannot have the same value as
the primary sector PN Offset. If the primary sector PN Offset is changed to the value of the secondary sector, the
secondary sector will be adjusted to the next higher value to avoid conflict. If the next higher value is out of range, the
next lower value will be used instead.
136
The secondary traffic channel can only be set if there is no power in the secondary sector.
137
This is the same as “FER Interval” in the Softer Handoff Configuration menu. Changes via the remote interface will appear
in the menu, and vice–versa.
