Measurements Technical Specifications
Transmitter measurements continued
Measurement accuracy (at +10 °C from the calibration temperature):
RMS EVM:
TD-SCDMA and TD-HSDPA, < 2%,
TD-HSUPA: < 3%, typically< 2%
Frequency error:
TD-SCDMA and TD-HSDPA: < ±10Hz + timebase accuracy
TD-HSUPA: < ±15Hz + timebase accuracy, typically < ±10Hz
Peak code domain error:
< ±0.2 dB (typically < ±0.15 dB) for Bands 34 and 39
< ±0.25 dB (typically < ±0.2 dB) for Bands 40 and 41
Measurement triggers: Auto, immediate, protocol, external, and RF rise Other reported
parameters:
–– Magnitude error
–– Phase error
–– Origin offset
–– Timing error
Temperature range: +15 to +55 °C
Adjacent channel leakage ratio (ACLR)
Measurement method: The ratio of the RRC filtered mean power centered on the adjacent
channel frequency to the RRC filtered mean power centered on the assigned channel
frequency. The adjacent channels are located at ±1.6 MHz and ±3.2 MHz offsets
Measurement level range: +5 to +28 dBm/1.28 MHz; measured signal level is expected
within ±9 dB of the expected power and has a < 10.0 dB crest factor
Frequency capture range: –20 to +20 kHz from the expected measurement receiver
frequency
Timing capture range: –25 to +25 chips from the measurement trigger
Measurement accuracy (at ±10 °C from the calibration temperature): ±0.8 dB (typically
±0.5 dB) for measurements at –33 dBc at ±1.6 MHz offsets and
–43 dBc at ±3.2 MHz offsets
Residual ACLR floor: < –55 dBc for ±1.6 MHz offsets, < –60 dBc for ±3.2 MHz offsets
Measurement interval: 1 timeslot excluding the guard period, 662.5 µs
Measurement triggers: Auto, RF rise, protocol, immediate, and external
Temperature range: +15 to +55 °C
Transmit on/off power (TOOP)
Measurement method: Check whether the RRC filtered mean power versus time meets
the specified mask. The test set measures three timeslots excluding the leading and
the lagging guard period
Measurement level range: –65 to +28 dBm/1.28 MHz; measured signal level is expected
within ±9 dB of the expected power and has < 10.0 dB crest factor
Frequency capture range: –20 to +20 kHz from the expected measurement receiver
frequency for TD-SCDMA channel type; –2 to +2 kHz from the expected measurement
receiver frequency for HSDPA channel type
Timing capture range: –25 to +25 chips from the measurement trigger
TOOP noise floor: < ±0.2 dB (typically < ±0.15 dB) for Bands 34 and 39
< ±0.25 dB (typically < ±0.2 dB) for Bands 40 and 41
Measurement interval: 3 timeslots excluding the leading and the lagging guard period
Measurement triggers: Auto, RF rise, protocol, immediate, and external
Temperature range: +15 to +55 °C
