Amplitude
Composite Signal Output Level Range
• RF In/Out:
−
109 dBm/1.23 MHz to
−
21.5 dBm/1.23 MHz.
Usable to
−
127 dBm/1.23 MHz with reduced level accuracy.
• Duplex Out:
−
109 dBm/1.23 MHz to
−
7.5 dBm/1.23 MHz.
Usable to
−
127 dBm/1.23 MHz with reduced level accuracy.
Composite Signal Output Level Accuracy (using the IS-98 sensitivity setup)
• RF In/Out:
AWGN Off:
±1.5
dB.
AWGN On:
±2.0
dB.
• Duplex Out: .
AWGN Off:
±1.5
dB.
AWGN On:
±2.0
dB.
Composite Signal Output Power
• Equal to the sum of the individually settable power levels for AWGN, Sector A, and
Sector B.
Maximum Individual Signal Dynamic Range
• The maximum dynamic range of any CDMA channel (AWGN, Sector A: Pilot, Sync,
Paging, Traffic, or OCNS, Sector B: Pilot, Traffic, or OCNS) is from 0 dB to
−
30 dB
relative to the total composite output power. The dynamic range of the Paging and
Traffic channels will vary depending on the data rate in use.
AWGN Bandwidth
• Typically > 1.8 MHz bandwidth. Because the reported total composite power and
AWGN power is in terms of dBm in a 1.23 MHz bandwidth, the actual broadband
output power as seen by a power meter on the front panel will be higher than reported
on the front panel.
Sector A OCNS Channel Relative Level Range
• Automatically calculated from other Sector A channel relative levels to provide the set
Sector A total power.
Sector B OCNS Channel Relative Level Range (HP 8924C Only)
• Automatically calculated from other Sector B channel relative levels to provide the set
Sector B total power.
