Base Station Test

Field inspection and feeder link in one workflow

The core challenge in base station scenarios is that bench instruments can't be carried out, while cheap handhelds lack noise floor and excitation capability. HTOOL's solution uses SA8T/SA8/SV6301A as main tools, covering interference locating, feeder testing and link power adjustment.

1Spectrum scanning and interference location

SA8T (13.5MHz–8.2GHz) or SA8 (35MHz–6.2GHz) for quick RF environment analysis, cellular repeater status check, and repeater/filter maintenance. SA8T reaches -105dBm noise floor with 0.75s full-span sweep, plus spectrogram for intermittent interference. Pair with HT8 log-periodic antenna (100MHz–12GHz, 7–12dBi gain) for outdoor antenna deployment and direction finding.

2Feeder link fault diagnosis

VNA6 VNA (1MHz–6.3GHz) TDR time-domain reflectometry locates feeder cable breaks, crush damage or impedance discontinuities directly, no need to disassemble sections, significantly reducing outdoor O&M time. SA8T's S21 transmission measurement also tests filters, duplexers and power dividers for insertion/return loss.

3Fine power adjustment on the RF link

DA08 RF attenuator (9KHz–8GHz, 0–31.5dB adjustable, ≤±0.2dB step accuracy) features compact design for direct integration into base station RF modules, wide-temperature design for outdoor deployment, used for 4G/5G base station RF link power stabilization.
