LTE Base Station Transmitter (Tx) Comprehensive Test Workflow (3.5GHz Band)
Connection: MS2830A (6GHz model) connects to LTE base station Tx port via RF cable. Enables built-in vector signal generator (as calibration stimulus). LAN port connects to control PC (running LTE test software)
Configuration:
- Band & Signal: 3.5GHz (Band 42), LTE FDD signal (100MHz bandwidth, 64QAM)
- Measurements:
- Output Power: Target +43dBm (±0.5dB), utilizes ±0.3dB accuracy to ensure ≤0.3dB error
- ACLR: Adjacent Channel Leakage Ratio (Requirement ≥-45dBc@±10MHz offset)
- EVM: Error Vector Magnitude (Requirement ≤3%@64QAM)
- Noise Figure: Base station receive chain (Tested with external attenuator, requirement ≤6dB)Test Execution:
- Closed-loop testing:
- Stimulus generation: Built-in signal generator outputs -50dBm LTE calibration signal to base station receiver
- Transmission measurement: Analyzer receives base station transmit signal, measures power 43.2dBm (Pass), ACLR -47dBc (Pass), EVM=2.5% (Pass)
- Noise figure: Switch to noise figure test mode, measures 5.8dB (≤6dB → Pass)Optimization Verification: If a batch of base stations shows ACLR of -44dB (slightly out-of-spec), adjust power amplifier bias voltage (from 28V to 29V). Retest ACLR improves to -46dB (Pass), power fluctuation 0.1dB (Within tolerance)
Usage Precautions
1. For mmWave band testing (>13.5GHz), use low-loss mmWave cables (e.g., WR-28 waveguide, loss ≤0.5dB/m) and perform port calibration (via built-in calibration kit) to avoid >1dB power measurement error from connector mismatch
2. Before modulation analysis, load corresponding standard test software (e.g., LTE R15) to ensure demodulation algorithm match. Otherwise EVM measurement may be inaccurate (e.g., missing WLAN software causes 802.11ac signal EVM misjudgment)
3. In low-power mode (110VA), ensure adequate cooling (ambient temperature ≤30°C) to avoid temperature drift (≤0.1dB/°C) affecting accuracy during prolonged high-power testing (>20dBm)
