20 | Keysight | E1963A W-CDMA Mobile Test Application - Technical Overview
W-CDMA RF analyzer (measurements only)
Real-time demodulation of: Uplink DPCH
W-CDMA Tx measurements
Thermal power measurement
Measurement bandwidth: > 5 MHz; if other signals are present outside of this frequency
range, reduced measurement accuracy will result
Measurement data capture period: 10 ms
Measurement range: –10 to +28 dBm; usable to –20 dBm with degraded accuracy
Measurement level ranging: Auto
Auto zero function: Measurement automatically zeros the thermal power meter (no user control)
Measurement accuracy: (With 10 internal averages)
–– 375 to 500 MHz < ±6.6%, typically < ±3.0%
–– 698 to 1000 MHz < ±6.0%, typically < ±3.0%
–– 1400 to 1500 MHz < ±7.2%, typically < ±3.7%
–– 1700 to 2000 MHz < ±7.2%, typically < ±3.7%
–– 2480 to 2580 MHz < ±8.7%, typically < ±3.7%
Temperature range: +20 to +55 °C

Channel power measurement
Measurement bandwidth
RRC filter off: Measured with a bandwidth greater than (1 + a) x chip rate,
where a = 0.22 and chip rate = 3.84 Mcps
RRC filter on: Measured with a filter that has a root-raised cosine (RRC) filter response
with roll-off a = 0.22 and a bandwidth equal to the chip rate (3.84 MHz bandwidth centered
on the active uplink channel)
Measurement range: –61 to +28 dBm/3.84 MHz
Measurement interval: Settable from 0.01 to 12 ms
Measurement triggers: Auto, immediate, protocol, external, and RF rise
Measurement accuracy
(at +10 °C from the calibration temperature):
–– < ±1.0 dB (typically < ±0.5 dB) for measurement intervals of 333 μs to 12 ms over
698 to 1024 MHz, 1400 to 1500 MHz, and 1700 to 2000 MHz
–– < ±1.0 dB (typically < ±0.55 dB) for measurement intervals of 333 μs to 12 ms over
2480 to 2580 MHz
–– < ±1.0 dB (typically < ±0.55 dB) for measurement intervals of 67 to < 333 μs over
698 to 1024 MHz, 1400 to 1500 MHz, and 1700 to 2000 MHz
Temperature range: +20 to +55 °C
Temperature drift: Typically 0.1 dB per 10 °C temperature change
