Measurement input level range: −20 to +30 dBm
Measurement averaging: default of 100, selectable
Marker relative level accuracy (averages > 25):
+5 to −22 dB: <±0.4 dB + 0.1 dB for signal fall times less than
2 µs, typically < ±0.30 dB
−22 to −25 dB: < ±0.7 dB + 0.2 dB for signal fall times less than
2 µs, typically < ±0.55 dB
Marker level resolution: 0.01 dB
Measurement limits: time domain mask per IS-98D
Graphical results: zoom view
Full trace: displays a time window of 1277 µs centered on the
burst; grey bar indicates which section of the full trace appears
in the zoomed trace
Time display range: −15 to +1262 µs
Level display range: −35 to +5 dB
Zoom position: 0 to 13
Zoomed trace: displays a zoomed section of the full graph
Zoomed time display resolution:
Zoom views 0, 13: 68 ns
Zoom views 1 to 12: 276 ns
Time display range:
Zoom view 0: −15.06 to +10.04 µs
Zoom view 1: +10.21 to +112.21 µs
Zoom view 2: +112.47 to +214.47 µs
Zoom view 3: +214.74 to +316.74 µs
Zoom view 4: +317.00 to +419.01 µs
Zoom view 5: +419.28 to +521.27 µs
Zoom view 6: +521.55 to +623.54 µs
Zoom view 7: +623.81 to +725.54 µs
Zoom view 8: +725.81 to +827.81 µs
Zoom view 9: +828.08 to +930.07 µs
Zoom view 10: +930.35 to +1032.34 µs
Zoom view 11: +1032.61 to +1134.61 µs
Zoom view 12: +1134.88 to +1236.88 µs
Zoom view 13: +1237.05 to +1262.14 µs
Level display range: −35 to +5 dB
Graphical results: rise/fall view
Rise trace:
Time display range: −15 to +1262 µs
Time display resolution: 68 ns
Level display range: −35 to +5 dB
Fall trace:
Time display range: −15 to +1262 µs
Time display resolution: 68 ns
Level display range: −35 to +5 dB
Other measurement results: pass/fail indicator, first all point time
and level, and mask shift (indicates the time shift required to
center IS-98D mask on the burst); full trace is available via
GPIB
Concurrency capabilities: none
Frame error rate measurement
FER measurement method: data loopback in service options 002,
009, and 055 with confidence limits
FER input level measurement range: −65 dBm/1.23 MHz to
+30 dBm/1.23 MHz
FER measurement residual error rate: < 1 x 10^-6 for input levels in
the specified input level range and within ±9 dB of the
expected input power
Confidence limit range: definable from 80.0 to 99.9% and off
FER reported parameters:
Intermediate results: measured FER, number of errors, and
number of frames tested (updated every 25 frames)
Final results: measured FER, number of errors, number of
frames tested, and one of the following: passed confidence
limit, failed confidence limit, or max frames
Concurrency capabilities: FER measurements can be made
concurrently with all CDMA measurements that support
concurrency
Conditions for terminating FER test:
Max frames: maximum number of frames to test completed –
indeterminate test result
Failed: measured FER failed the specified FER limit with
specified confidence
Passed: measured FER passed the specified FER limit with
specified confidence
FER measurement indicators: testing, passed, failed, and max
frames all are available over GPIB
