Time response of open loop power control measurement
Input frequency ranges:
411 to 420 MHz
450 to 484 MHz
824 to 934 MHz
1700 to 1980 MHz
Measurement method: measures the open loop power versus
time response of a mobile to a 20 dB step in the test set’s cell
power
Measurement data capture period: 100 ms
Measurement trigger: user initiated
Maximum input level: +37 dBm/1.23 MHz peak (5 W peak)
Measurement range: −46 to +30 dBm (final level after ±20 dB
step in cell power)
Measurement level ranging: auto
Measurement cell power step size: +20 dB, −20 dB
Marker relative level accuracy: ±0.5 dB
Marker time accuracy: ±540 µs
Measurement limits: time versus amplitude mask per IS-98D
Graphical results:
Graph: single trace with IS-98D standard limit lines
Time display resolution: 270 µs
Time display range: 0 to +100 ms
Amplitude range: −5 to +30 dB
Available results: pass or fail result and trace of 371 data points
available via GPIB
Concurrency capabilities: none; selecting this measurement
automatically closes all other active measurements
Tx spurious emissions
Input frequency ranges:
411 to 420 MHz
450 to 484 MHz
824 to 934 MHz
1700 to 1980 MHz
Measurement method: measures the active carrier power in a
1.23 MHz bandwidth, then measures the power in a 30 kHz
bandwidth at two offsets above and below the active carrier
and displays the ratio of the offset powers to the active carrier
power in dBc; measurement returns valid results for full rate
only in R-RC1 or R-RC2; all rates are supported in R-RC3 and
R-RC4
Measurement data capture period: 5 ms
Measurement offsets:
Frequencies < 1000 MHz: ±885 kHz, ±1.98 MHz
Frequencies > 1000 MHz: ±1.25 MHz, ±1.98 MHz
Measurement bandwidth:
Active carrier: 1.23 MHz
Offsets: 30 kHz synchronously tuned, five pole filter with
approximately Gaussian shape
Measurement trigger: 20 ms frame clock
Maximum input level: +37 dBm/1.23 MHz peak (5 W peak)
Measurement range: 0 to +30 dBm
Measurement level ranging: auto
Marker relative level accuracy:
±885 kHz, ±1.25 MHz offets: < ±0.4 dB, typically < ±0.2 dB
±1.98 MHz offsets: < ±0.8 dB, typically < ±0.5 dB
Measurement residual relative power:
±885 kHz, ±1.25 MHz offets: < −62 dBc/30 kHz BW
±1.98 MHz offsets: < −66 dBc/30 kHz BW
Mobile pass/fail limits (per IS-98D):
Auto mode:
Frequencies < 1000 MHz:
−42 dBc/30 kHz for ±885 kHz offsets
−54 dBc/30 kHz for ±1.98 MHz offsets
Frequencies > 1000 MHz:
−42 dBc/30 kHz for ±1.25 MHz offsets
−50 dBc/30 kHz for ±1.98 MHz offsets
Manual mode: settable from −10 to −65 dBc with 0.01 dB
resolution
Numeric results: relative power in dBc/30 kHz for each of the
four offset frequencies
Graphical results:
Graph: single trace with IS-98D standard limit lines and one bar
representing the channel power and four bars representing the
relative power at the four offset frequencies
Amplitude range: 0 to −80 dB
Concurrency capabilities: Tx spurious emissions measurements
can be made concurrently with all CDMA measurements that
support concurrency
