CDMA analyzer (continued)
Maximum/minimum power measurement
Input frequency ranges 411 to 420 MHz
450 to 484 MHz
824 to 934 MHz
1700 to 1980 MHz
Measurement method
Performs this sequence:
–– Sets the test set source to a user-specified
value for the maximum power measure-
ment
–– Ranges the receiver to the expected
power
–– Sends all up power control bits
–– Uses the average power meter to measure
the maximum power
–– Sets the test set source to a user-specified
value for the minimum power measure-
ment
–– Ranges the receiver to the expected
power
–– Sends all down power control bits
–– Uses the channel power meter to measure
the minimum power
–– Returns the test set to the same state
before the measurement was initiated
Measurement data
capture period
1.25 ms
Maximum input level +37 dBm/1.23 MHz peak (5 W peak)
Measurement range
Maximum power measurement: −10 to
+30 dBm; usable from −10 to −20 dBm with
reduced accuracy (peak detector only)
Minimum power measurement: −61 to
+30 dBm; usable to < −69 dBm/1.23 MHz with
reduced accuracy
Measurement level
ranging:
Auto for the maximum power measurement,
and either auto or manual for the minimum
power measurement
